• Aaron076 MDX Matrix.RotateX not doing what I expected...

  I wrote this code: Matrix Test = Matrix.Identity; Test.RotateX( ( float )Math.PI/2.0f ); Test.RotateY( ( float )Math.PI/2.0f ); expecting it to rotate 90 degrees in X and then in Y. But the second rotate call (RotateY), simply replaces the matrix with a Y rotation. I expected it to post-catenate the Y rotation and createa compound rotation. Is this the intended use of RotateX etc. The help says that Matrix.RotateX "Rot ...Show All

• John Chef Multiple windows by one device

  Hi! I'm looking for some easy way to render into multiple widows by only one device. I'm using managed directX in C#, there's an overload of the Present method that takes a control and claims that it will draw onto the control, but I can't make it work. It does not fail, but neither does it draw anything. Could you please tell me what I'm doing wrong, or maybe weather there's some easier way to do that Thanks Libor ...Show All

• Kroamian multichannel audio

  Hi there, I'm wondering if it is possible to program a soundcard with e.g. 5.1 option as if it had 6 mono channels. I already tried faking it with directsound3D but with no success... I wan't to be able to play a sound on e.g. channel 1 and 5 (frontleft and backright) but not on the other channels. If this is not possible using directx anyone got an idea on what else to use I think this must be possible ONE way... Thanks in advance, Pat ...Show All

• thegrave About ID3DXRenderToEnvMap::Face()

  I saw DX9SDK 2002 samples' CubEnvMapping. I followed that and wrote one program myself. When I ran it, found that the rendered Cubmap is something wrong(broken), so think to fix it for a long time. At last, I found that after the lpRenderToEnvMap->Face( (D3DCUBEMAP_FACES) i, 0 ); means starts to render to a face of cubemap, I add the lpD3DDev->Clear(0,NULL,D3DCLEAR_TARGET | D3DCLEAR_ZBUFFER, D3DCOLOR_XRGB(100,100,100),1.0f,0); in order to ...Show All

• seattleboatguy Video Card support

  What video cards will be able to support DirectX 10 Well I can't be 100% sure, you will need someone from MS for that but every presentation I have seen says "you will need new hardware" and as Jack said nobody has any of this new hardware yet so I doubt the "new hardware" is generally on sale. Just to add to what ZMan said... I would imagine that the D3D10 hardware won't be making an appearance un ...Show All

• rcook349 Creating a simulation using Direct3D

  Hello, I am working on a project to create a simluation of a football (or soccer ball) flight after it has been kicked. This includes velocity, spin, etc in 2D and then 3D.

  I'm a really RAW recruit into the gaming world. I'm by profession a VB6/Oracle/ programmer and haven't ever looked further than that until now. I'm teaching myself C# using the excellent Microsoft Visual C# .Net Express Edition and have started on the 101 webcasts for 2d games, and it's slow heavy going for my non-oo, database-centric brain to get hold of, but I'll get there .. in the end ...

• Peter Boulton A question of desgin

  This question isn't directly related to DirectX, but it's still strongly tied into the whole idea of game programming, so I'm hoping someone here can give me some direction. Up until now, developing my game logic hasn't been too hard. I have a World object, which contains Platform objects, Item objects, and one Hero object. With an object oriented design, this is insanely easy to implement, because all the basic attributes and drawing logic c ...Show All
