Yes, Direct3D does provide access to the texture matrix. You set each texture stage's matrix with a call to d3dDevice->SetTransform( D3DTS_TEXTUREi, PointerTo4x4Matrix );

I know nothing about coding, but: no.
And if by some miracle someone could, I don't wanna play FS2 at 0.2 frames per second

calculating the matrix may be a pain though.  is there a way you can select it and transform from there ex:

Code: [Select]


glActiveTextureARB(GL_TEXTURE0_ARB); //select tex0
glMatrixMode(GL_TEXTURE);                    //start editing texture matrix
glTranslatef(x,y,z);                                  //translate - x,y,z are floats
glMatrixMode(GL_MODELVIEW);             //go back to using the modelview matrix


i don't know your opengl experience, but it should speak for itself even tho i added comments

erm, the resulting matrix should be
| 1 0 0 x |
| 0 1 0 y |
| 0 0 1 z |
| 0 0 0 1 |

That's simple enough.
The problem doesn't lie in that. The problem is due to the fact that if you want to do multitexturing in Direct3D without both textures having the same texture coordinates, you have to define a new FVF. Annoying.

a effect like that would make a SHadw ship come ALIVE! Hint! Hint!;7

Procedural textures have to be calculated at the beginning of each animation frame, then passed to the texture buffer. Not pretty. Venom is absolutely right: even on a modern system this would kill the frame rate.

Mind you, the impact would be far less if you were to implement the procedural as a shader that the GPU could handle natively. Even then it would only work on cards that had support for programmable shaders.

And then there's the ever-amusing task of writing the shader out.  Although that's probably not as hard as I imagine it is.

does the FSO readme give instructions for how to use the cloaking effect?

1.  model = invisible
2.  lightning texture takes .pof shape
3.  couple seconds, model textures appear from 100% trans
4.  lightning texture overlayed on model texture for a bit
5.  lightning texture fades, think the Blizzard intro

Animated textures have been available in the SCP for a while now.  All you need to do is whip up a cloaking animated texture ahead of time, and then use change-ship-model to switch to the cloaking textures and back again.

[NecroBob]

yeah, I know .ani's are, but procedural textures, like textures generated by an algorithm at and during run-time

(think Unreal water or forcefields)

[EDIT]
bleh, read the responses.  if so, then why did Unreal run on my 233 in 320x240 software at 60 FPS?
and on my 850 duron in 1024x768 with all the spiffy tweaks on at 60+ FPS?

i thought unreal water was a form of cube-mapping, or are we talking not UT2/UT2003

Unreal Tournament 2k3 indeed does water with cube-mapping. The original Unreal and UT, on the other hand, do water by generating a fractal and doing some fake refraction on it procedurally.
