This creates an instance of a TetGen expression:

This sets up points and facets to use:

This sets the points and facets in the TetGen instance:

This sets up variables that specify a point within a material domain as well as a region attribute and a region constraint:

The material variables are set in the TetGen instance:

This carries out the tetrahedralization, returning a new TetGen instance. The switch "A" is needed to process the material data:

This extracts the points and faces from the tetrahedralization:

This plots the faces:

Each element now carries the material attribute:
