Useful for offline editors though
hendu you should add some specular lighting to your shots because they amplify the effect of normal mapping
What's the limitaton? I know I was trying to do something similar, but shaders only give you information for the current vertex/pixel. ddx_fine/ddy_fine look like functions that allow the GPU to provide the missing information, but where are they available?
Also, does the technique in the paper require you *not* to use vertex shaders? That is, will it only work if there isn't a vertex shader?
