Random experiment: demo -> time cube

Oh and actually we used the shader also in catharsis. It's inside the .zip if you want to take a look.

similarly we have one for raycasting 3d smoke and so on.
are all your frames on quads in one texture?

All the textures are separate and 2d unfortunately. I could render them into a single texture with a shader and a bit of cunning, 256^3 is only a 4k x 4k texture. Then raycasting would be possible with a bit more cunning (and probably a huge amount of shaking fist while i figure out how the hell the texture lookups work :).

Pommak: thanks, I'll take a look at the catharsis shader. It's GLSL too, that will help :)

Btw, any suggestions for a good demo to convert next? It needs to have good contrast/sharp lines, and good synch.

hm, was thinking if doing this realtime, the fact that it's based on the framerate could heart quite a bit if you get framedrops..

If the framerate drops it makes no difference - I'm loading one frame from the video per frame rendered. Makes it painful to set the parameters up right though, I have to watch for several minutes to see how it looks :(

Warrior: I'll have a play with that, it could work well. There's a traction demo that looks really promising too, lots of nice shapes and synch :)

(i was thinking more like not using video, but render to texture and save the frame) etc.. anyway, go on :)
