• Grégoire de Jabrun OBB Collision Detection getting it to work

  I have some source for OBB (Orientated Bounding Box) Collision Detection. I'm certain the code is working correctly. However under only certain position will the two boxes collide correctly together. I'm sure i'm putting the rotation and translation data into the matrices wrongly. Though for the life of me i cannot see how the data was ment to be put into the algorithm in the first place. Both boxes are rotated (so both should have ...Show All

• Parag_Dave Using Hardware with DirectX

  This is a bit of a sticky one and I don't know how this happened. I recently upgraded my DirectX SDK to the Dec 2005 release. Prior to this the samples and other applicatons that I have compiled ran very fast and were using my hardwares capabilities. I have a 64MB NVIDIA GeForce2 MX. After the upgrade the samples want to switch into Reference. And of course everything runs slow. I have search all around the web and other forums for similar pr ...Show All

• Ben - ECM Question on ID3DXEffect::SetArrayRange

  Hi, I'm currently adding shader instancing to our engine. After I changed the single world matrix in the effect file to a matrix array, I noticed a heavy performance drop. The fps went down by almost 30%. After some investigation I found that the fps changes with the size of the matrix array, so the effect framework seems to always copy all elements of the array, not only those that were actually set. I then wanted to optimize this using the ID3 ...Show All

  Hi! I've made a game as a school project using VB and DirectX 8. The game is a side-scrolling platform game and it has some very confusing (for me) problems. When I tested the game on some of the computers at my school, they rebooted (instantly) at a particular point of the game. This problem occurs only on some computers. A similar problem came up a while ago, but that time the similarity was all computers with the problem had ATI grap ...Show All
