We present an interpreted language and system supporting the visualization of
unstructured meshes and the manipulation of shapes defined in terms of mesh
subsets. The language features primitives inspired by geometric modeling,
mathematical morphology and algebraic topology. The adaptation of the topology
ideas to an interpreted environment, along with support for programming
constructs such as user function definition, provide a flexible system for
analyzing a mesh and for calculating with shapes defined in terms of the mesh.
We present results demonstrating some of the capabilities of the language, based
on an implementation called the Shape Calculator, for tetrahedral meshes in R3 .
