This is from the DX7 SDK, www.tomspeed.com/bumpearth.zip
It's a feature not utilized in B3D, kinda like environmental bumpmapping.
But for the same bottlenecks here: http://www.blitzbasic.com/Community/posts.php?topic=59602 I could probably get this method working from a DLL.
It was dzzling back in the day, but it still looks good and it's all done on the GPU, shame B3D aint using it.
