Branched texture maps
Layers of a branched texture map

The following steps generate a brached texture map:

• cover the surface 1-1 with a virtual base texture  (e.g. by generating a piecewise isometric texture map)
• associate to every virtual base texel a stack of  texels whose height depends on the number of layers above the point on the surface.
• color all texels according to the numerical problem
• specify a blending procedure which a renderer  uses to blend the texels of each layer and obtain  the final texture color

Every base texel has an associated stack of texels (here: height of stack = 3 ) whose height may vary within the texture domain.
