• How to create projection/view matrix for hole in the monitor effect

  - by Mr Bell

  Lets say I have my XNA app window that is sized at 640 x 480 pixels. Now lets say I have a cube model with its poly's facing in to make a room. This cube is sized 640 units wide by 480 units high by 480 units deep. Lets say the camera is somewhere in front of the box looking at it. How can I set up the view and projection matrices such that the front edge of the box lines up exactly with the edges of the application window? It seems like this should probably involve the Matrix.CreatePerspectiveOffCenter method, but I don't fully understand how the parameters translate on to the screen. For reference, the end result will be something like Johhny Lee's wii head tracking demo: http://www.youtube.com/watch?v=Jd3-eiid-Uw&feature=player_embedded P.S. I realize that his source code is available, but I am afraid I haven't been able to make heads or tails out of it.

• What are best practices when giving a presentation to programmers?

  - by blunders

  I've watched 50 plus presentations on programming topics, although most have been online; example, Google Tech Talks -- and have ad-hoc experience on what formats work for programmers, or practices to take into account when presenting to a group of programmers. That said, I'm open to any suggestions, but here's some topic of the top of my head: Programming Jokes, Images, etc. Posting Code for download Contact Info Collecting feedback Presenting Code on Screen If it matters, in this case -- I'm giving a presentation on using a scripting language to extract, transform and load data to a local user group who's focus is the scripting language; Ruby in this case. Questions, feedback, requests -- just comment, thanks!!

• Efficient skeletal animation

  - by Will

  I am looking at adopting a skeletal animation format (as prompted here) for an RTS game. The individual representation of each model on-screen will be small but there will be lots of them! In skeletal animation e.g. MD5 files, each individual vertex can be attached to an arbitrary number of joints. How can you efficiently support this whilst doing the interpolation in GLSL? Or do engines do their animation on the CPU? Or do engines set arbitrary limits on maximum joints per vertex and invoke nop multiplies for those joints that don't use the maximum number? Are there games that use skeletal animation in an RTS-like setting thus proving that on integrated graphics cards I have nothing to worry about in going the bones route?

• A glitch after Ubuntu Installation. Cannot boot Ubuntu

  - by Starx

  I am trying to create a dual boot of Ubuntu 10.10 with Windows 7. My hard disk allocation were as follows: Windows 7 NTFS 100 GB /boot EXT4 200 MB SWAP LINUX SWAP 4 GB / EXT4 46 GB After installation is complete, instead of getting the boot screen of Ubuntu, it directly boots from windows 7 without asking anything. What is wrong? I run the Live Cd again using USB drive and I see that the \boot, and \ are occupied with most likely Ubuntu data. Now How do i point my Laptop to point to Ubuntu Boot instead of Windows Boot

• Scene Graph Traversing Techniques

  - by Bunkai.Satori

  Scene Graph seems to be the most effective way of representing the game world. The game world usually tends to be as large as the memory and device can handle. In contrast, the screen of the device captures only a fraction of the Game World/Scene Graph. Ideally, I wish to process(update and render) only the visible game objects/nodes on per-frame basis. My question therefore is, how to traverse the scene graph so, that I will focus only on the game notes that are in the camera frustum? How to organize data so that I can easily focus only on the scene graph nodes visible to me? What are techniques to minimize scenegraph traversal time? Is there such way as more effective traversal, or do I have to traverse whole scene graph on per-frame basis?

• Xubuntu dual monitor broke display

  - by Arman yaraee

  After I used Settings Display to enable my second monitor, my first display is not working anymore either. So I enabled both, then clicked save configuration since it was working and boom it crashed. Now when I start up, I can see the screen which I type my password but it goes black after that! When I boot into recovery mode it works fine but in Settings Display I don't see HDMI at all to disable it. Is there anyway to restore all display setting to default? (I can Ctrl+ALT+F1 and type commands but xrandr returns no results over there) EDIT I should clarify that system bios is set to laptop display

• Fan always spinning on Maverick

  - by jb

  I use Dell Studio 1555, after update to maverick my fan started spinning full speed allways. I use xserver-xorg-video-ati/radeon drivers because fglrx messes with my desktop resolution when connecting external screen. Processor is mostly idle. U use some desktop effects. On the same configuration on Lucid my fan worked slower. It eats lots of battery time :( Bug filed: https://bugs.launchpad.net/ubuntu/+source/xserver-xorg-video-ati/+bug/675156 Any insights how to solve/debug it or work around it?

• Accept keyboard input when game is not in focus?

  - by Corey Ogburn

  I want to be able to control the game via keyboard while the game does not have focus... How can I do this in XNA? EDIT: I bought a tablet. I want to write a separate app to overly the screen with controls that will send keyboard input to the game. Although, it's not sending the input DIRECT to the game, it's using the method discussed in this SO question: http://stackoverflow.com/questions/6446085/emulate-held-down-key-on-keyboard To my understanding, my test app is working the way it should be but the game is not responding to this input. I originally thought that Keyboard.GetState() would get the state regardless that the game is not in focus, but that doesn't appear to be the case.

I thought this a unity bug in asus kxxvd series! is there any solution for this problem?

• Font rendering in Firefox is blurry

  - by Mehrdad

  A picture is worth a thousand words... so does anyone know how to fix this font blurriness in Firefox? (You'll need to right-click the picture below go to View Image to view it full-size; it's too small to see anything here.) Note: My other applications (and the Firefox non-client area, as you can see in the screen) are completely fine, so obviously going to System-Appearance and changing the font settings isn't fixing the situation. Edit: Not letting web pages to use their own fonts also doesn't help: See how the upper one is still sharper? Also, Firefox's own menu bar doesn't render the same way as the page content (menu bar below, page content above). They're both Segoe UI:

• How to make a battle system in a mobile indie game more fun and engaging

  - by Matt Beckman

  I'm developing an indie game for mobile platforms, and part of the game involves a PvP battle system (where the target player is passive). My vision is simple: the active player can select a weapon/item, then attack/use, and display the calculated outcome. I have a concept for battle modifiers that affect stats to make it more interesting, but I'm not convinced the vision is complete. I've received some inspiration from the game engine that powers Modern War/Kingdom Age/Crime City, but I want more control to make it more fun. In those games, you don't have the option to select weapons or use items, and the "battling" screen is simply 3D eye candy. Since this will be an indie game, I won't be spending $$$ on a team of professional 3D artists/animators, so my edge needs to be different. How would you make a battle system like this more fun and engaging?

• How to code a 4x shader/filter which emulates arcade crt display behavior?

  - by Arthur Wulf White

  I want to write a shader/filer probably in adobe Pixel Bender that will do the best job possible in emulating the fill of an oldskul monochromatic arcade CRT screen. Much like this here: http://filthypants.blogspot.com/2012/07/customizing-cgwgs-crt-pixel-shader.html Here are some attributes I know will exist in this filter: It will take in a low res image 160 x 120 and return a medium res image 640 x 480. It will add scanlines It will blur the color channels to create that color bleeding effect It will distort the shape of the image from a perfect rectangle into a rounder shape. The question is, could you please provide any other attributes that are beneficial to emulating an arcade CRT feel and links and resources on coding these effects. Thanks

• Chmod 777 to a folder and all contents on Apache web server

  - by Ryan Murphy

  I have just got new hosting for my website and I have a directory /www which I put all my website files within and a folder in that directory called 'store'. Within 'store' is several files and folders, I want to give the folder 'store' and all files and folders within the 'store' folder all permissions. How do I do this? I am guessing via .htaccess. I have tried inserting chmod 777 -R /store Into the .htaccess file but didn't work. Threw a big on screen error at me. I want to make all the files and folders within /store writable.

• as3 3D camera lookat

  - by Johannes Jensen

  I'm making a 3D camera scene in Flash, draw using drawTriangles() and rotated and translated using a Matrix3D. I've got the camera to look after a specific point, but only on the Y-axis, using the x and z coordinates, here is my code so far: var dx:Number = camera.x - lookAt.x; var dy:Number = camera.y - lookAt.y; var dz:Number = camera.z - lookAt.z; camera.rotationY = Math.atan2(dz, dx) * (180 / Math.PI) + 270; so no matter the x or z position, the point is always on the mid of the screen, IF and only if y matches with the camera. So what I need is to calculate the rotationX (which are measured in degrees not radians), and I was wondering how I would do this?

• usb devices unacessible

  - by Dustin

  I have a funny thing happening with my USB devices. They are detected and show up as they should but I cannot write to them, I can read the files in them. I cannot change the Group folder access. It keeps reverting to none when I try change it. However when I start a guest session and copy a screen shot to the USB I can, but cannot in my regular administration session. Why cannot I change the option and why does it behave properly in a guest session but not normally? Anyone know how to help me out here? I am using Ubuntu 12.04, 32-bit.

• Web application Project management methodologie

  - by dutchiexl

  I am looking to streamline my company's web development process. Including analysis. I myself am specialized in XP and Scrum. But we are building web application with a process cycle of 3-4 weeks and a lifetime of 1-4 months. When a project is sold, only then the project managers (= people who do analysis but know nothing about it = a small flow chart and some screen shots as analysis) What is happening is: A LOT of change requests Minimal development time Minimal analysis time NOW: the main question :) can you recommend me some methodologies and books to read for the entire project management ? Thanks in advance @Edit, I myself was looking at a combination of SCRUM for the management with flowcharts, + RAD/LD for development, and trying to distilate something from that.

• How do I log into bash shell only?

  - by Tom D

  On my home desktop I want to use Ubuntu Unity sometimes and just the bash shell (without any gui) other times. Is it possible to set up a login option where I can choose between using the Unity GUI or just the shell? For example, on the Ubuntu login screen I can choose among Unity, Gnome Shell, XFCE, etc. An option there for just the Bash shell command line would be ideal. I'm not trying to invite "why would you do that" debate here. I have my reasons. Thanks.

• DIY Internet Radio Maintains Controls and Interface of Vintage Case

  - by Jason Fitzpatrick

  Updating an old radio for modern inputs/streaming audio isn’t a new trick but this DIY mod stands out by maintaining the original controls and interface style. Rather than replace the needle-style selector window with a modern text-readout or cover-flow style interface, modder Florian Amrhein opted to replace the old rectangular station selector with an LCD screen that emulates the same red-needle layout. Using the same knob that previously moved the needle on the analog interface, you can slide the digital selector back and forth to select Internet radio stations.

• Bastion unexpectedly exits when I move my cursor

  - by user69358

  I downloaded the Humble Indie Bundle V, mostly because my friend told me about how great Bastion was. When I first installed it, I was getting the seemingly common "black screen" error that most people got (fixed that half with this http://ubuntuforums.org/showthread.php?p=11992661). But I also have an error where every time I move my cursor, in any direction, any amount, the game closes instantly. I can use the keyboard no problem, but without fail, every time I move my mouse, it crashes. Does anyone know what might be causing this? Has anyone encountered anything like this before? I am worried it may be a hardware issue, but hoping someone might be able to help me out. I'm running Ubuntu 12.04 on a Dell Studio 1558. Graphics card is the stock Intel graphics card, running on 4 GB of RAM.
