Has this been done before?
I store the polygon colour surfaces as barycentric vectors instead of accessing bitmaps, this way you needent unwrap the model, I was thinking it could be handy for doing extended environmental work.
So its like flash vector graphics, on the surface of the low poly models.
?
Do you mean something like this?
It is somewhat more expensive than ordinary texture sampling, and you need some pre-processing to simplify the geometry to pieces that the hardware can easily handle.
In practice, the actual rendering is very fast on modern hardware.
so it is in development, i thought it was a good idea.
I will implement, but what I do will simpler than this and just record brush strokes on the surfaces on the triangles and raster them with flat coloured triangles, i figure itll give me something similar to hand made cell shading, big brushstrokes would be for ambient occlusion, small tight strokes for inbetween bricks and things. (im actually 60% artist 40% programmer)
Will be back with a post if i get anywhere with it.
