  • Render graphics using Doubles in Graphics2D

    - by thedeadlybutter
    Currently, I have a JFrame for my game to render in, and I'm using Graphics2D for drawing (The games graphics are fairly simple 2D sprites). However, my delta variable is a double, and all of the Graphics 2D methods (And Grpahics) use int. I tried to type cast the delta to an int, but it just rounds down to 0. So my question is, how can I render graphics using Graphics2D in Java with coordinates that are doubles. Can I convert it to work with Graphics2D if there is no built in way? Or, is there a graphics library that can support doubles for coordinates?

  • Should I get integrated graphics if I already have a dedicated GPU?

    - by Ivo Flipse
    I want to upgrade my computer to the new Sandy Bridge CPU's, which features integrated graphics. However, you have to choose between two types of chipsets: H67 or P67. Now since I already own a GTX 460, so is there any added value to using the integrated graphics? Would there be a way of 'disabling' my GPU when I don't need it's additional power or would the integrated graphics simply allow me to add another screen?

  • How can I use my built-in AMD Radeon 7670m instead of Intel HD 4000 Graphics?

    - by gururaj
    i recently bought a DELL Inspiron 15R 2012m Series Laptop. It comes with a built-in AMD Radeon 7670m graphics card. I installed PES 2012, when I checked the system specification (an option in that PES 2012 game ). I came to know that game runs with Intel HD4000 Graphics and not with my AMD card. I also changed the swithchable graphics and assigned High Performance to PES2012, but the game still runs on Intel HD4000.

  • Tracking graphics tablet input in C#

    - by Martin
    I'm writing an XNA application with C#, and I want to be able to control the application with a graphics tablet. All I need to be able to do is track the position and pressure of the pen on the tablet, it would be nice to have some built in gesture recognition but I'm willing to build that myself if needed. My first attempt at this was to use the vbtablet library. However, when I sent this to a friend it failed to work. It seems that the underlying technology is quite old and not supported by some tablets. My second attempt is to play with the Microsoft.Ink system. This looks promising, but I know very little about this subject and I'm struggling to make it work properly - for example I can't find how to read the raw tablet input and disable mouse pointer mode on the tablet when using an InkOverlay. What's the best system to use and what good documentation is there for a beginner in this field?

  • Graphics.RotateTransform works on localhost, but not on remote server

    - by harriyott
    It works on my machine... I'm combining two map pins into a single image. I load an empty pin image and write a number on top of it. I then combine two of these, having rotated one 15 degrees and the other -15 degrees. It looks fine running through my localhost web server: I upload this to my shared server, and I get this instead: I load the image thus: var g = Graphics.FromImage(image); The line to rotate the image is: g.RotateTransform(angle); I'm sure this must be a setting somewhere, but I've had no luck finding it.

  • Display On-Screen Television Graphics During Live Broadcasts

    - by ServAce85
    How and with what software do major television companies display on-screen graphics during their programs? For example: On ESPN, how do they produce the news ticker on the bottom (both graphically and from a source code point of view), create and display the scores of sports, and update and show selected stats on the fly? I've looked everywhere I can think of to find the answer, but I am at a loss. That's where you guys (and girls) come in. I hope you can help shed some light on this subject for me. Thanks in advance.

  • What are good resources for computer graphics basics?

    - by Hanno Fietz
    During Flex programming, I recently ran into several questions (about box models, ways to join lines and misaligning pixels [on doctype]) regarding computer graphics and layout, where I felt that I lacked some basic background on things like concepts like the box model approaches mapping real numbers to a pixel raster (like font anti-aliasing) conventions found across drawing engines, like do you count y coordinates from top or bottom, and why I feel that reading some basic Wikipedia articles, books or tutorials on these subjects might help in phrasing my questions more specifically and debugging my code more systematically. I have repeatedly found myself writing tiny test apps in Flex, just to find out how the APIs do very basic stuff. My assumption would be that if I knew the right vocabulary and some general concepts, I could solve these questions much faster.

  • Draw rectangle using Core Graphics with live preview

    - by mikawber
    I'm creating a simple drawing application and would like some help with drawing rectangles based on the user's touch events. I'm able to draw a rectangle using Core Graphics from the point in touchesBegan to the point in touchesEnded. This rectangle is then displayed once the touchesEnded event is fired. However, I would like to be able to do this in a 'live' fashion. Meaning, the rectangle is updated as the user drags their finger. Is this possible? Any help would be greatly appreciated, thank you!

  • Profiling and Graphics.updateDisplay0()

    - by AD
    I am profiling my BlackBerry application (a game) with the options 'In method only' and 'Time including native method'. Under the 'All methods' node (after a decent run of the game) the single most time consuming function is Graphics.updateDisplay0() with over 50% of the run time spent there. I don't quite know what is the purpose of that function or if I can do anything to reduce its processing time, so if anyone can shed some light on the matter, I would be grateful. Because from what I understand with the 'In method only' option, it means there is some processing within that function. ps. there is no information on that function in the documentation.

  • Ubuntu hangs at the '_' prompt for 15' when booting. Do I need another driver for my Intel G31/G33 integrated graphics?

    - by Doctoa
    I have an ASROCK which uses Intel G31 graphics. Ubuntu says my graphics chipset is G33. Should I look for another driver or are they from the same family? I am also having problems booting and that purple screen stuck so for this I asked this question. I have partially fixed the purple screen stuck by enabling (uncommenting) this line in grub: GRUB_TERMINAL=console But Ubuntu still hangs at start up for about 15 minutes with a black screen and only the '_' prompt. Here is a link for an overview of my ASROCK G31M-S

  • How do graphics programmers deal with rendering vertices that don't change the image?

    - by canisrufus
    So, the title is a little awkward. I'll give some background, and then ask my question. Background: I work as a web GIS application developer, but in my spare time I've been playing with map rendering and improving data interchange formats. I work only in 2D space. One interesting issue I've encountered is that when you're rendering a polygon at a small scale (zoomed way out), many of the vertices are redundant. An extreme case would be that you have a polygon with 500,000 vertices that only takes up a single pixel. If you're sending this data to the browser, it would make sense to omit ~499,999 of those vertices. One way we achieve that is by rendering an image on a server and and sending it as a PNG: voila, it's a point. Sometimes, though, we want data sent to the browser where it can be rendered with SVG (or canvas, or webgl) so that it can be interactive. The problem: It turns out that, using modern geographic data sets, it's very easy to overload SVG's rendering abilities. In an effort to cope with those limitations, I'm trying to figure out how to visually losslessly reduce a data set for a given scale and map extent (and, if necessary, for a known map pixel width and height). I got a great reduction in data size just using the Douglas-Peucker algorithm, and I believe I was able to get it to keep the polygons true to within one pixel. Unfortunately, Douglas-Peucker doesn't preserve topology, so it changed how borders between polygons got rendered. I couldn't readily find other algorithms to try out and adapt to the purpose, but I don't have much CS/algorithm background and might not recognize them if I saw them.

  • What's the best way to install the GD graphics library for Nagios?

    - by user1196
    While trying to install Nagios 3.2.3, I ran their ./configure script and got these errors: checking for main in -liconv... no checking for gdImagePng in -lgd (order 1)... no checking for gdImagePng in -lgd (order 2)... no checking for gdImagePng in -lgd (order 3)... no checking for gdImagePng in -lgd (order 4)... no *** GD, PNG, and/or JPEG libraries could not be located... ********* Boutell's GD library is required to compile the statusmap, trends and histogram CGIs. Get it from http://www.boutell.com/gd/, compile it, and use the --with-gd-lib and --with-gd-inc arguments to specify the locations of the GD library and include files. NOTE: In addition to the gd-devel library, you'll also need to make sure you have the png-devel and jpeg-devel libraries installed on your system. NOTE: After you install the necessary libraries on your system: 1. Make sure /etc/ld.so.conf has an entry for the directory in which the GD, PNG, and JPEG libraries are installed. 2. Run 'ldconfig' to update the run-time linker options. 3. Run 'make clean' in the Nagios distribution to clean out any old references to your previous compile. 4. Rerun the configure script. NOTE: If you can't get the configure script to recognize the GD libs on your system, get over it and move on to other things. The CGIs that use the GD libs are just a small part of the entire Nagios package. Get everything else working first and then revisit the problem. Make sure to check the nagios-users mailing list archives for possible solutions to GD library problems when you resume your troubleshooting. ******************************************************************** Which package do I want? libgd2-xpm-dev? libgd2-noxpm-dev? php5-gd? I'm not looking to do any image processing myself - I just want to get Nagios working.

  • How to review the current state of open source vs. closed source graphics drivers?

    - by Bucic
    How to know whether it's worth it to replace open source drivers installed by default with proprietary ones. Are there any benchmarks? Major known issues summaries. I don't mean 'at the time of writing this post'. I mean an up-to-date status on how the drivers compare. This page https://help.ubuntu.com/community/BinaryDriverHowto/ certainly doesn't do much on the matter, nor it even mentions Intel. EDIT: I've just learned there is no Intel proprietary driver because they made their drivers open source http://askubuntu.com/a/17395/29347

  • Choice of Input / music / graphics libraries for an indie game - what factors should I consider?

    - by RusselMeMan
    I was wondering which tools (grapics-sound-input libraries, game engine libraries) that the following indie games used: Braid Superbrothers: S&S Super Meat Boy Limbo Fez (I know this one is XNA) Also, what is in common use in production games? My guess for game development in C++ is: -DirectX is most common for  Windows games -SDL or SDL+OpenGL is most common for  Linux games -OpenGL + Apple APIs are most common for OSX development What do most indie game projects use? If I wanted to casually build my own game for fun in C++ with the idea of possibly releasing it to Steam or something someday, is there anything I should be concerned about if I make it with DirectX for music/sound/input and build my own game engine? Thanks!

  • Why doesn't 12.04 recognize my ATI Radeon X300SE graphics card?

    - by Nomad Zero
    So far everything including the BCM4321 card is working, however, the OEM ATI Radeon X300SE (RV370) is not recognized. When I go into system details the card comes up as unknown. When I run lspci the card shows up as: 01:00.0 VGA compatible controller: Advanced Micro Devices [AMD] nee ATI RV370 5B60 [Radeon X300 (PCIE)] 01:00.1 Display controller: Advanced Micro Devices [AMD] nee ATI RV370 [Radeon X300SE] I have attempted check Additional Drivers but the card does not show up as needing a driver. So far this is causing the system to run warmer as the processor is doing a bit of the work to run Unity and any full screen videos tend to be rather choppy. Is there an available driver that will fix my issue and what is the install method? I am not scared to run a terminal so no worries there, as long as I have instructions, I can find my way. I am running under 12.04 LTS Kernel 3.2.0-25-generic-pae

  • How can I create animated card graphics like in Hearthstone?

    - by Appeltaart
    In the game Hearthstone, there are cards with animated images on them. A few examples: http://www.hearthhead.com/card=281/argent-commander http://www.hearthhead.com/card=469/blood-imp The animations seem to be composed of multiple effects: Particle systems. Fading sprites in and out/rotating them Simple scrolling textures A distortion effect, very evident in the cape and hair of example 1. Swirling smoke effects, the light in example 1 and the green/purple glow in example 2. The first three elements are trivial, what I'd like to know is how the last two could be done. Can this even be done realtime in a game, or are they pre-rendered animations?

  • Does a laptop with a GPU also use IGP?

    - by blee
    I have a Thinkpad T60 with dual screen setup: The laptop's LCD: Is normal looking. VGA external monitor: Looks "wavy," but I hooked it up to another computer and it looked fine. Does this imply my GPU is connected to the VGA-out and the built-in LCD is driven by IGP? Is this typically how a laptop with one GPU works? Thanks.
