As discussed in Moray.win on the same subject:
Two images to show the use of image bump_maps
First one (bump is almost invisible):
Plane: bump size 2 scale <2,2,1> translate <-1,-1,0> (planar mapping)
Sphere: bump size 1 (spherical mapping)
Cylinder: bump size 1 (cylindrical mapping)
Second one (bump is evident):
Plane: bump size 2 scale <2,2,10> translate <-1,-1,0> (planar mapping)
Sphere: bump size 10 (spherical mapping)
Cylinder: bump size 10 (cylindrical mapping)
