Dot 3 Bump Mapping

Blitz3D Forums/Blitz3D Programming/Dot 3 Bump Mapping

how did i manage to generate Dot 3 bump mapping (what i mean the texture with rainbow color - not just white/black bump mapping)

the big commercial apps can do this. they can do something that makes it useful at all: make a normalmap using the details of the shape of a highly detailed Model and draw it to the UV of a Lowpoly version of this Mesh.

Here's Atis Standalone Normalmapper:

There are also some plugins for photoshop or gimp to create nomalmaps from heightmaps etc., but this doesn't make much sense to me.

thanqs... but is it compatible with all VGA? im afraid that my game willnt compatible with certain comp?

it is not compatible with generation 1 hardware accelerated cards.

You need a Geforce or better.

I guess there is a function to detect compatibility?

For Cubemapping it was:
If GfxDriverCaps3D()>=110

Maybe it's the same for dot3?
