This effect makes surfaces appear bumpy. Children nodes must use two textures,
2003-09-08 18:51:14 +08:00
one for diffuse color and one for the normal map (which can be created
from a height map with tools like nVIDIA's normal map generator). Furthermore,
tangent-space basis vectors must be created and assigned to each Geometry; this
2003-09-10 16:35:16 +08:00
can be done quickly by calling BumpMapping::prepareChildren(). Note that both
2003-09-08 18:51:14 +08:00
diffuse and normal map textures must have corresponding UV maps defined in
Geometry objects.
This effect defines a preferred technique which uses ARB vertex & fragment
programs, and a fallback technique which doesn't use fragment programs. The
latter is more limited though since it can't handle ambient and specular
components.< / BLOCKQUOTE >
