  • Surface RT: To Be Or Not To Be (Part 1)

    - by smehaffie
    So the Surface RT has been out for 9 months and Microsoft just declared a $900 million dollar write-down. So how did this happen and what does it mean for Microsoft’s efforts to break into the tablet market? I have been thinking a lot about most of the information below since the Surface product line was released. If you are looking for a “Microsoft Is Dead” story, then don’t read any further. But if you want an honest look at what I think led Microsoft to this point and what I think can be done to make Surface RT devices better, then please continue reading. What Led Microsoft To The $900 Million Write-Down Surface Unveiling:Microsoft totally missed the boat when they unveiled the Surface product line on June 18th, 2012. Microsoft should’ve been ready to post the specifications of both devices that night. Microsoft should’ve had a site up and running right after the event so people could pre-order the devices. This would have given them a good idea what the interest was in each device.  They could also have used this data to make a better estimate for the number of units to to have available for the launch and beyond.  They also lost out on taking advantage of the excitement generated by the Surface RT and Surface Pro announcement. They could have thrown in a free touch keyboard to anyone who pre-ordered. The advertising should have started right after the announcement and gotten bigger as launch day approached. Push for as many pre-order as possible and build excitement for the launch. Actual Launch (Surface RT): By this time all excitement was gone from the initial announcement, except for the Micorsoft faithful. Microsoft should have been ready to sell the Surface in as many markets as possible at launch. The limited market release was a real letdown for a lot of people.  A limited release right after the initial announce is understandable, but not at the official launch of the product. Microsoft overpriced the device and now they are lowering it to what it should have been to start with. The $349 price is within the range I suggested it should be at before pricing was announced. (Surface Tablets: The Price Must Be Right). Limited ordering options online was also a killer. User should have been able to buy the base unit of each device and then add on whatever keyboard they wanted to (this applies more to the Surface Pro).  There should have also been a place where users could order any additional add-ins that they wanted to buy (covers, extra power supplies, etc.) Marketing was better and the dancing “Click In” commercial was cool, but the ads comparing the iPad with Siri should have been on the air from day one of the announcement (or at least the launch).  Consumers want to know why you tablet is better, not just that is has a clickable keyboard and built-in kickstand. They could have also compared it to some of the other mid-range tablets if they had not overprices it to begin with. Stock Applications (Mail, People, Calendar, Music, Video, Reader and IE): This is where Microsoft really blew it. They had all the time in the world to make these applications the best of breed and instead we got applications that seemed thrown together.  Some updates have made these application better, but they are all still lacking in features that should have been there from day one. This did not help to enhance a new users experience any. ** I will admit that the applications that were data driven were first class citizen’s and that makes it even more perplexing why MS could knock it out of the park with the Weather, Travel, Finance, Bing, etc.) and fail so miserably on the core applications users would use the most on a tablet. Desktop on Tablet: The desktop just is so out of place on the tablet  I understand it was needed for Office but think it would have been better to not have the desktop in Windows RT, but instead open up the Office applications in full screen mode, in a desktop shell (same goes for  IE11).That way the user wouldn’t realize they are leaving Metro and going to the desktop. The other option would have been to just not include Office on Windows RT devices. Instead they could have made awesome Widows Store Apps for Word, Excel, OneNote and PowerPoint. In addition, they could have made the stock Mail, People, and Calendar applications contain all the functions that Outlook gives desktop users. Having some of the settings in desktop mode and others under “Change PC Settings” made Windows RT seemed unfinished and rushed to market. What Can Be Done To Make Windows RT Based Tablets Better (At least in my opinion) Either eliminate the desktop all together from Windows RT or at least make the user experience better by hiding the fact the user is running Office/IE in the desktop. Personally I ‘d like them to totally get rid of it and just make awesome Windows Store Application version of Word, Excel PowerPoint & OneNote.  This might also make the OS smaller and give the user more available disk space. I doubt there will ever be a Windows Store App versions of Office, but I still think it is a good idea. Make is so users can easily direct their documents, picture, videos and music to their extra storage and can access these files from the standard libraries.  A user should not have to create a VM on their microSD card or create symbolic links to get this to work properly. Most consumers would not be able to do this. Then users get frustrated when they run out or room on their main storage because nothing is automatically save to their microSD card when saved to libraries.  This is a major bug that needs to be fixed, otherwise Microsoft’s selling point of having a microSD slot is worthless. Allows users to uninstall and re-install any of the Office product that come with the Surface. That way people can free up storage space by uninstalling the Office applications they do not need. Everyone’s needs are different, so make the options flexible. Don’t take up storage space for applications the user will not use. Make the Core applications the “Cream of the Crop” Windows App Store applications. The should set the bar for all other Store applications. Improve performance as much as possible, if it seems to be sluggish on a tablet consumer will not buy it. They need to price the next line of Surface product very aggressive to undercut not only iPad but also Android low end tablets (Nook, Kindle Fire, and Nexus, etc.) Give developers incentives to write quality applications for the devices. Don’t reward developers for cranking out cookie cutter, low quality applications. I’d even suggest Microsoft consider implementing some new store certification guideline to stop these type of applications being published. Allow users to easily move the recover disk “partition between their microSD card and main storage. My Predictions for the Surface RT and Windows RT I honestly think even with all the missteps MS has made since the announcement  about the Surface product line, that they are on the right path. I was excited the Surface tablets when they were announced, and I still am. The truth be told, Windows 8 on a tablet (aka: Windows RT) is better than both iOS and Android. My nephew who is an Apple fan boy told me after he saw and used Windows 8 (he got the beta running on his iPad), that Windows 8 kicked Apples butt as a tablet OS. So there is hope for all Windows RT based tablets. I agree with my nephew and that is why whenever anyone asks me about my Surface, I love showing it off and recommend it. The 6 keys to gaining market share in the tablet market are; Aggressive pricing by both Microsoft and their OEM’s Good quality devices put out by Microsoft and their OEM’s (there are some out there, but not enough) Marketing, Marketing, Marketing from both Microsoft and their OEM’s (Need more ads showing why windows based tablets are better than iPads and Android tablets) Getting Widows tablets in retails stores all over, and giving sales people incentive to sell them. Consumers like to try electronics out before they buy them, and most will listen to what the sales person suggest. Microsoft needs sales people in retail stores directing people to buy windows based tablets over iPads and Android tablets. I think the Microsoft Stores within Best Buy is a good start, but they also need to get prominent displays in Walmart, Target, etc.. Release a smaller form factor Surface, Hopefully the 8”-10” next generation Surface is not a rumor. Make “Surface” the brand name for all Microsoft tablets and hybrid devices that they come out with. They cannot change the name with each new release.  Make Surface synonymous with quality, the same way that iPad  is for Apple. Well, that is my 2 cents on the subject. Let me know your thoughts by leaving a comment below. Soon to follow will be my thought on the Surface Pro, so keep an eye out for it. var addthis_pub="smehaffie"; var addthis_options="email, print, digg, slashdot, delicious, twitter, live, myspace, facebook, google, stumbleupon, newsvine";

  • Why isn't our c# graphics code working any more?

    - by Jared
    Here's the situation: We have some generic graphics code that we use for one of our projects. After doing some clean-up of the code, it seems like something isn't working anymore (The graphics output looks completely wrong). I ran a diff against the last version of the code that gave the correct output, and it looks like we changed one of our functions as follows: static public Rectangle FitRectangleOld(Rectangle rect, Size targetSize) { if (rect.Width <= 0 || rect.Height <= 0) { rect.Width = targetSize.Width; rect.Height = targetSize.Height; } else if (targetSize.Width * rect.Height > rect.Width * targetSize.Height) { rect.Width = rect.Width * targetSize.Height / rect.Height; rect.Height = targetSize.Height; } else { rect.Height = rect.Height * targetSize.Width / rect.Width; rect.Width = targetSize.Width; } return rect; } to static public Rectangle FitRectangle(Rectangle rect, Size targetSize) { if (rect.Width <= 0 || rect.Height <= 0) { rect.Width = targetSize.Width; rect.Height = targetSize.Height; } else if (targetSize.Width * rect.Height > rect.Width * targetSize.Height) { rect.Width *= targetSize.Height / rect.Height; rect.Height = targetSize.Height; } else { rect.Height *= targetSize.Width / rect.Width; rect.Width = targetSize.Width; } return rect; } All of our unit tests are all passing, and nothing in the code has changed except for some syntactic shortcuts. But like I said, the output is wrong. We'll probably just revert back to the old code, but I'm curious if anyone has any idea what's going on here. Thanks.

  • Connecting PC to TV via HDMI/DVI: Windows XP doesn't allow the appropriate screen resolution

    - by Jørgen
    I have a computer that is connected to the living room TV (a Panasonic) via HDMI. There is no other monitor connected. My problem is that the computer, which is running Windows XP, does not allow me to set the proper resolution for the TV. Both the graphics adapter and the TV should support the 1280x720 resolution, but it cannot be selected - the only available options are 1280x600 and 800x600, both in the "native" Windows dialog box and the custom Intel graphics options dialog box. Do anyone have a suggestion for a solution for this? Things I've thought of: Setting the resolution directly in the registry (where?) Installing some "custom" monitor driver (the TV manufacturer does not appear to provide any, currently the "generic" one is used) Details on the setup: Connection: DVI output on the computer via a passive DVI-HDMI adapter to the HDMI input on the TV, audio is run on a separate link, the TV is able to combine video and audio without any problem, the problem is there regardless of whether or not the audio is connected. The connection is several meters long through some walls, for this reason using a VGA cable instead is not an option. Note that the report explicitly says that the TV supports 1280x720. Still, I am not allowed to select it in Graphics Options, only 1280x600 and 800x600 is available. For 800x600, there's a lot of black around the edges; for 1280x600, the screen is "zoomed" so the edges of the monitor image (like the taskbar) is not visible. Other: The computer is running Windows XP. More recent versions of Windows are not an option (I have no licence). Linux is probably not an option (some of the video streaming sites I plan to use do not support it, I think) I wrote the rest of the details below. Thanks for any help!! TV: Panasonic TX-L32X10Y, European version; a 720p 32" quite "regular" LCD TV. Allowed resolutions according to manual: Signal name: 640x480 @60HZ Horizontal frequency: 31.47 kHz Vertical frequency: 60Hz Signal name: 750/720) /60p Horizontal frequency: 45.00 kHz Vertical frequency: 60Hz Signal name: 1,125 (1,080) / 60p Horizontal frequency: 67.50 kHz Vertical frequency: 60Hz (this is exactly how the manual presents it. PC via D-SUB (VGA cable) and "regular" HDMI have more alternatives.) Messing with the "zoom" settings on the TV does not affect the available resolution options on the computer. Computer: The following is a printout from one of the graphics adapter option pages. I think it covers most of it. The computer is a Dell. INTEL(R) EXTREME GRAPHICS 2 REPORT Report Date: 04/17/2011 Report Time[hr:mm:ss]: 20:18:02 Driver Version: 6.14.10.4396 Operating System: Windows XP* Professional, Service Pack 3 (5.1.2600) Default Language: English DirectX* Version: 9.0 Physical Memory: 1021 MB Minimum Graphics Memory: 1 MB Maximum Graphics Memory: 96 MB Graphics Memory in Use: 6 MB Processor: x86 Processor Speed: 2593 MHZ Vendor ID: 8086 Device ID: 2572 Device Revision: 02 * Accelerator Information * Accelerator in Use: Intel(R) 82865G Graphics Controller Video BIOS: 2972 Current Graphics Mode: 1280 by 600 True Color (60 Hz) * Devices Connected to the Graphics Accelerator * Active Digital Displays: 1 * Digital Display * Monitor Name: Plug and Play Monitor Display Type: Digital Gamma Value: 2.20 DDC2 Protocol: Supported Maximum Image Size: Horizontal: Not Available Vertical: Not Available Monitor Supported Modes: 1280 by 720 (50 Hz) 1280 by 720 (60 Hz) Display Power Management Support: Standby Mode: Not Supported Suspend Mode: Not Supported Active Off Mode: Not Supported (disclaimer: this question was also asked at the Wikipedia Reference Desk some time ago and might show up in a Google search.

  • How do I do JavaScript Array Animation

    - by Henry
    I'm making a game but don't know how to do Array Animation with the png Array and game Surface that I made below. I'm trying to make it so that when the Right arrow key is pressed, the character animates as if it is walking to the right and when the Left arrow key is pressed it animates as if it is walking to the left (kind of like Mario). I put everything on a surface instead of the canvas. Everything is explained in the code below. I couldn't find help on this anywhere. I hope what I got below makes sense. I'm basically a beginner with JavaScript. I'll be back if more is needed: <!doctype html5> <html> <head></head> <script src="graphics.js"></script> <script src="object.js"></script> <body onkeydown ="keyDown(event)" onkeyup ="keyUp(event)" ></body> <script> //"Surface" is where I want to display my animation. It's like the HTML // canvas but it's not that. It's just the surface to where everything in the //game and the game itself will be displayed. var Surface = new Graphics(600, 400, "skyblue"); //here's the array that I want to use for animation var player = new Array("StandsRight.png", "WalksRight.png", "StandsLeft.png","WalksLeft.png" ); //Here is the X coordinate, Y coordinate, the beginning png for the animation, //and the object's name "player." I also turned the array into an object (but //I don't know if I was supposed to do that or not). var player = new Object(50, 100, 40, 115, "StandsRight.png","player"); //When doing animation I know that it requires a "loop", but I don't // know how to connect it so that it works with the arrays so that //it could animate. var loop = 0; //this actually puts "player" on screen. It makes player visible and //it is where I would like the animation to occur. Surface.drawObject(player); //this would be the key that makes "player" animation in the righward direction function keyDown(e) { if (e.keyCode == 39); } //this would be the key that makes "player" animation in the leftward direction function keyUp(e){ if (e.keyCode == 39); } //this is the Mainloop where the game will function MainLoop(); //the mainloop functionized function MainLoop(){ //this is how fast or slow I could want the entire game to go setTimeout(MainLoop, 10); } </script> </html> From here, are the "graphic.js" and the "object.js" files below. In this section is the graphics.js file. This graphics.js part below is linked to the: script src="graphics.js" html script section that I wrote above. Basically, below is a seperate file that I used for Graphics, and to run the code above, make this graphics.js code that I post below here, a separate filed called: graphics.js function Graphics(w,h,c) { document.body.innerHTML += "<table style='position:absolute;font- size:0;top:0;left:0;border-spacing:0;border- width:0;width:"+w+";height:"+h+";background-color:"+c+";' border=1><tr><td> </table>\n"; this.drawRectangle = function(x,y,w,h,c,n) { document.body.innerHTML += "<div style='position:absolute;font-size:0;left:" + x + ";top:" + y + ";width:" + w + ";height:" + h + ";background-color:" + c + ";' id='" + n + "'></div>\n"; } this.drawTexture = function(x,y,w,h,t,n) { document.body.innerHTML += "<img style='position:absolute;font-size:0;left:" + x + ";top:" + y + ";width:" + w + ";height:" + h + ";' id='" + n + "' src='" + t + "'> </img>\n"; } this.drawObject = function(o) { document.body.innerHTML += "<img style='position:absolute;font-size:0;left:" + o.X + ";top:" + o.Y + ";width:" + o.Width + ";height:" + o.Height + ";' id='" + o.Name + "' src='" + o.Sprite + "'></img>\n"; } this.moveGraphic = function(x,y,n) { document.getElementById(n).style.left = x; document.getElementById(n).style.top = y; } this.removeGraphic = function(n){ document.getElementById(n).parentNode.removeChild(document.getElementById(n)); } } Finally, is the object.js file linked to the script src="object.js"" in the html game file above the graphics.js part I just wrote. Basically, this is a separate file too, so thus, in order to run or test the html game code in the very first section I wrote, a person has to also make this code below a separate file called: object.js I hope this helps: function Object(x,y,w,h,t,n) { this.X = x; this.Y = y; this.Velocity_X = 0; this.Velocity_Y = 0; this.Previous_X = 0; this.Previous_Y = 0; this.Width = w; this.Height = h; this.Sprite = t; this.Name = n; this.Exists = true; } In all, this game is made based on a tutorial on youtube at: http://www.youtube.com/watch?v=t2kUzgFM4lY&feature=relmfu I'm just trying to learn how to add animations with it now. I hope the above helps. If not, let me know. Thanks

  • Will Apple abandon OpenCL?

    - by John
    I am developing OpenCL applications, amongst others for MacOS. The new Macbook pro 13 inch comes with an Intel HD Graphics 3000 card so it seams reasonable to assume all their mainstream computers like Macbook and Mac mini will also come out with this Intel graphics card soon. OpenCL is not available for Intel graphics cards. Intel having a terrible reputation in developing graphics drivers and Apple knowing this makes me wonder Apple is abandoning OpenCL already again. Especially considering OpenCL should run anywhere, not only on high end systems. Developing applications only for the high end Macs with dedicated graphics hardware or for previous generation hardware with the Geforce 320M would not be a feasible option for me. Does anybody have any thoughts on this?

  • Limiting Row Selection in JTable

    - by Pat
    Is there an easy way to limit the total selection of rows in a JTable? I mean I'd like to allow the user to use shift and ctrl to select a maximum of X rows. If he clicks again on a row it would cancel out all the selections. Sort of how it currently behaves, but while limiting the total amount of selected rows. Here's my current implementation, I'm kind of clueless on how to limit the selection graphically. public class RoomsListView extends AbstractViewPanel { public RoomsListView(DefaultController controller) { this.controller = controller; initUI(); } private void initUI() { tableT = new JTable(RoomsModel.getInstance()); sorter = new TableRowSorter<RoomsModel>(RoomsModel.getInstance()); tableT.setRowSorter(sorter); tableT.setPreferredScrollableViewportSize(new Dimension(CUSTOM_TABLE_WIDTH, CUSTOM_TABLE_HEIGHT)); tableT.addMouseListener(new MouseAdapter() { public void mouseClicked(MouseEvent e) { rowClickedPerformed(e); } }); } private void rowClickedPerformed(MouseEvent e) { } public void modelPropertyChange(PropertyChangeEvent evt) { } public JTable getTable() { return tableT; } private final int CUSTOM_TABLE_WIDTH = -1; private final int CUSTOM_TABLE_HEIGHT = 150; private JTable tableT; private DefaultController controller; private TableRowSorter<RoomsModel> sorter; }

  • How can I make a game like doodlejump XNA c#

    - by Ramy
    I wanted to know how can I make the background scroll down like doodlejump. I have a game made and I have to transform it so it's like doodle jump, but I'm wonder how or where to look so I can make he background keep moving as in progressing through the background till let's say the character dies. namespace IFM20884 { using System; using System.Collections.Generic; using System.Linq; using System.Text; using Microsoft.Xna.Framework; using Microsoft.Xna.Framework.Content; using Microsoft.Xna.Framework.Graphics; public abstract class BackgroundScroll : Sprite { private float speedOfBackground = 0.2f; // speed that the background moves public BackgroundScroll (GraphicsDeviceManager graphics) : base(graphics.GraphicsDevice.Viewport.Width / 2f, graphics.GraphicsDevice.Viewport.Height / 2f) { } //Getter public float speedOfBackground { get { return this.speedOfBackground ; } set { this.speedOfBackground = value; } } public override void Update(GameTime gameTime, GraphicsDeviceManager graphics) { //Makes background go down. ForcePosition(Position.X, Position.Y + (gameTime.ElapsedGameTime.Milliseconds * this.speedOfBackground )); if (Position.Y - (Height / 2) > graphics.GraphicsDevice.Viewport.Height) { ForcePosition(Position.X, Position.Y - this.Height); } } public override void Draw(SpriteBatch spriteBatch) { ForcePosition(Position.X, Position.Y - this.Height); base.Draw(spriteBatch); ForcerPosition(Position.X, Position.Y + this.Height); base.Draw(spriteBatch); } } }

  • Android: 2D. OpenGl or android.graphics?

    - by DroidIn.net
    I'm working with my friend on our first Android game. Basic idea is that every frame the whole surface is redrawn (1 large bitmap) which then sprinkled all over with large number of particles which produces effect of soapy bubbles where there's a pool of about 20 bitmaps which randomly gets picked to produce illusion that all bubbles (between 200 - 300) are all different. The math engine is in C (JNI) and currently all drawing is done using android.graphics package very similar (since that was the example I was using) to Lunar Lander. It works but animation is somewhat jerky and I can feel by temperature of my phone that it is very busy. Will we benefit from switching to OpenGL? And as a bonus question: what would be a good way to optimize the drawing mechanism (Lunar Lander like) we have now?

  • Why does installing NVidia 9600GT graphics card, take 1GB of RAM away from Windows?

    - by Nick G
    Hi, I've changed graphics cards in my PC and now Windows 7 (32bit) is reporting that I have a whole gigabyte less physical RAM in my PC. Why is this? Firstly, the machine has 4GB of physical RAM. The old card was an ATI 2600XT with 256MB and the new card is an NVidia 9600GT with 512MB. With the ATI card windows sees 3326MB. With the NVidia card, windows sees 2558MB. I realise that due to address space restrictions I will not see all 4GB with 32bit windows, but why is there such a massive loss of RAM when simply changing cards (bearing in mind BOTH cards have their own RAM and borrow no main memory like some built on chipsets do). Would using 64 bit windows solve this? Thanks Nick.

  • Get graphics information from font file. How to develop font parser similar to PDFView's font parser

    - by HBA
    Hi, I am trying to convert text into graphics using c#. My input is character string and output is bitmap with the input text. After lot of search I found some ways to do it, I found some techiques which uses this kind of techinque. For Example While creating Captcha, we have to print the character in the bitmap. But for that I should have the font installed in my windows. I can not perform such operation without installing the font. I have .ttf file with me but I dont want to install it because my work for that font is temporary only. Is there any way where I can extract out the Font's graphical information by providing the Character? I have also found font parser code http://swinglabs.java.sun.com/hudson/job/PDFRenderer%20Weekly%20Build/javadoc/com/sun/pdfview/font/package-summary.html Can anyone please provide me how to develpo similar thing using c#.Net? Or From where can I get the algorithm to parce font?

  • OpenGL ES 1.1 vs 2.0 for 2D Graphics, with rotated sprites?

    - by Lee Olayvar
    I am having trouble finding information related to which i should choose, OpenGL ES 1.1 or 2.0 for 2D graphics. OpenGL ES 1.1 on Android is a bit limited to my knowledge, and based purely on sprite count the only useful renderer is draw_texture() (as far as i know). However, that does not have rotation and rotation is very important to me. Now with the NDK adding support for OpenGL ES 2.0, i am trying to figure out if there is anything that preforms as well as draw_texture(), but can handle rotation. Anyone have any information on if 2.0 can help me in this area?

  • C# 2D Vector Graphics Game using DirectX or OpenGL?

    - by Brian
    Hey Guys, So it has been a while since I have done any game programming in C#, but I have had a recent bug to get back into it, and I wanted some opinions on what configuration I should use. I wanted to use C# as that is what I use for work, and have become vary familiar with. I have worked with both DirectX and OpenGL in the past, but mostly in 3D, but now I am interested in writing a 2D game with all vector graphics, something that resembles the look of Geometry Wars or the old Star Wars arcade game. Key points I am interested in: • Ease of use/implementation. • Easy on memory. (I plan on having a lot going on at once) • Looks good, I don't want curve to look pixelated. • Maybe some nice effects like glow or particle. I am open to any and all suggestions, maybe even something I have not thought of... Thanks in advance!

  • What's the best graphics library for node.js for image cropping?

    - by Travis
    I'm creating a website using node.js. I have seen many libraries mentioned that piggy back on top of imagemagick etc. There is a list here: https://github.com/ry/node/wiki/modules#graphics What I'm trying to do is take the image that a user uploads, crop it/size it to certain dimensions the site requires. What is the best/most active script to do this? I'd like one with npm support. Does anyone have actual experience using some of these?

  • Make graphics on left and right side of text change width depending on the amount of text?

    - by Dustin McGrew
    I need to have an H1 tag centered between two graphics on the left and right of the text. The H1 text will be various widths depending on what page you are on. The dot on the left should stay on the left edge of the site and the line should extend until it reaches the edge of the text. Same for the right side. Is there a way to accomplish this by using CSS or even some jquery/javascript? In the attached graphic, if the text was just "WHO YOU ARE" I'd need the bars on the left and right to grow wider to bump up against the edges of the text.

  • Why do I get this file loading exception when trying to draw sprites with libgdx?

    - by BluFire
    I'm having trouble with the "Drawing Images" section on the libgdx tutorial. I set up the documents completely and I typed the code as follows: public class Game implements ApplicationListener { public static final String LOG = Game.class.getSimpleName(); private FPSLogger fpsLogger; private SpriteBatch batch; private Texture texture; private Sprite sprite; private TextureRegion region; //removed irrelevant code for this question... @Override public void render() { texture = new Texture(Gdx.files.internal("android.png")); region = new TextureRegion(texture, 20, 20, 50, 50); sprite = new Sprite(texture, 20, 20, 50, 50); sprite.setPosition(10, 10); sprite.setRotation(45); Gdx.gl.glClearColor(0f, 1f, 0f, 1f); Gdx.gl.glClear(GL20.GL_COLOR_BUFFER_BIT); batch.begin(); batch.draw(texture,10,10); batch.draw(region,10,10); sprite.draw(batch); batch.end(); // output the current FPS fpsLogger.log(); } } I went through the tutorial on the website but when I run the code I get errors: Exception in thread "LWJGL Application" com.badlogic.gdx.utils.GdxRuntimeException: Couldn't load file: android.png at com.badlogic.gdx.graphics.Pixmap.<init>(Pixmap.java:137) at com.badlogic.gdx.graphics.glutils.FileTextureData.prepare(FileTextureData.java:55) at com.badlogic.gdx.graphics.Texture.load(Texture.java:175) at com.badlogic.gdx.graphics.Texture.create(Texture.java:159) at com.badlogic.gdx.graphics.Texture.<init>(Texture.java:133) at com.badlogic.gdx.graphics.Texture.<init>(Texture.java:122) at com.game.Game.render(Game.java:46) at com.badlogic.gdx.backends.lwjgl.LwjglApplication.mainLoop (LwjglApplication.java:163) at com.badlogic.gdx.backends.lwjgl.LwjglApplication$1.run(LwjglApplication.java:113) Caused by: com.badlogic.gdx.utils.GdxRuntimeException: File not found: android.png (Internal) at com.badlogic.gdx.files.FileHandle.read(FileHandle.java:108) at com.badlogic.gdx.files.FileHandle.length(FileHandle.java:364) at com.badlogic.gdx.files.FileHandle.readBytes(FileHandle.java:156) at com.badlogic.gdx.graphics.Pixmap.<init>(Pixmap.java:134) ... 8 more I set the android.png in my assests folder in my android project linking it to the desktop one, I don't understand what I'm doing wrong. What is making these errors? FIX. Weird ending.this was the plus where the sprite is suppose to look like. The top right corner of the next image should look like, the bottom left is what turned out in the code. I'm think it was because of the texture region but I'm not 100%. Can somebody explain why it is really warped? I thought the changes I made in the coding will just change position/rotation, rather then a change in the image.

  • Looking at desktop virtualization, but some users need 3D support. Is HP Remote Graphics a viable solution?

    - by Ryan Thompson
    My company is looking at desktop virtualization, and are planning to move all of the desktop compute resources into the server room or data center, and provide users with thin clients for access. In most cases, a simple VNC or Remote Desktop solution is adequate, but some users are running visualizations that require 3D capability--something that VNC and Remote Desktop cannot support. Rather than making an exception and providing desktop machines for these users, complicating out rollout and future operations, we are considering adding servers with GPUs, and using HP's Remote Graphics to provide access from the thin client. The demo version appears to work acceptably, but there is a bit of a learning curve, it's not clear how well it would work for multiple simultaneous sessions, and it's not clear if it would be a good solution to apply to non-3D sessions. If possible, as with the hardware, we want to deploy a single software solution instead of a mishmash. If anyone has had experience managing a large installation of HP Remote Graphics, I would appreciate any feedback you can provide.
