• SincerePrayer Converting a ray into object space

  Hello, I have been stuck on trying to convert a ray into object space, for simple collision detection, I have tried multiplying the coordinates of the ray with the objects inverse matrix ( x = x*_11 + y*_12 + z*_13, y = etc..) but that does not seem to work. There should not be any problems with detecting the collision as I am usuing the D3DXIntersect() function with this ray and the objects mesh. The current code I am using is: D3DXVECTOR ...Show All

• BramSWA XNA Installation Problems?

  Hi there, I've gone ahead and installed the XNA package, following the instructions in the download. The prerequisite's, Visual Studio Partner Edt, and the XNA installer. I've however not downloaded the MechCommander2 package yet. I wanted to see if this was any bit usable without it. I fire up Visual Studio and attempt to make one of it's "content build", and am greeted with a number of exciting errors. Of note, the content build proj ...Show All

• JoeM setting position of sphere

  Hi! I am using DirectX 9.0 and VC++ .NET. I am trying to create a sphere (for collsion detection) but the application crashes on a particular line.

Please somebody help me. I am attaching the code and the line is marked in green. Following is the functi ...Show All

• Tan Silliksaar Direct3D and DXVA

  I'm using DirectShow and VMR9 in renderless mode to draw video into a texture which I can then composite via Direct3D. However, I can't seem to figure out how to get it to work with DXVA. I can allocate DXVA format _surfaces_ in my allocator/presenter, but I can't seem to create DXVA _textures_. Does anyone know how to either create DXVA textures, or render DXVA surfaces via Direct3D    Thanks in advance for any help,    ...Show All

• Ralph Scowden Unit size

  Hi, I don't understand how to define units in my model and world space. I have loaded a mesh, and if I don't scale it down it is very large. When I modeled it in a 3d modeler i modeled it to be about 50cm X 50cm X 70cm. When I load in the mesh it is very big. I want to define it so that 1 unit = 50 cm. And the screen is about 10x10 units. How can I do this I you don't understand my question, please tell me and I will try to explain my problem in ...Show All

• jr78 Sprite size changes when the window size changes!!

  Hello,       There is a problem which I suffers from a lot. When I draw a sprite with scaling 1:1 in a windowed mode it draws perfect with the same size as it's power of 2. When I resize the window I found all the sprites sizes changes and I can't get it's new size for purposes such picking it and know if the mouse cursor position intersect with this region.

• Alex Paterson Confused about transformation pipeline...

  Hi, I'm writing a simple 3D engine. It's my first attempt at this so I apologize in advance if I seem new at this. ( I am. ) I'm having trouble understanding the order of things when transforming the vertex buffers. I read some articles about frames (frame of reference), but I'm not able to grasp how a single frame (screen buffer) is rendered in terms of the order that each frames (frame of reference) is transformed. Say I have a ...Show All

• Poofy Windows Tooltips kill FPS in my Windowed 3D application?

  Hi all. For a while now, I've noticed on my machine (and others) that when some WINDOWED 3D applications/games are running on Windows (XP/2000 etc), the framerate can drop from 80+ FPS to 5-10FPS if a standard Windows "tooltip" happens to over-lap the 3D window I hope that made sense! The reason it is an issue is because my application runs in a Maximized (not Fullscreen) window directly ontop of the windows desktop (ef ...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
