| Abstract |
A shell map is a bijective mapping between shell space and
texture space that can be used to generate small-scale features
on surfaces using a variety of modeling techniques. The
method is based upon the generation of an offset surface and
the construction of a tetrahedral mesh that fills the space between
the base surface and its offset. By identifying a corresponding
tetrahedral mesh in texture space, the shell map
can be implemented through a straightforward barycentriccoordinate
map between corresponding tetrahedra. The generality
of shell maps allows texture space to contain geometric
objects, procedural volume textures, scalar fields, or
other shell-mapped objects.
