The initial input to my system is a surface description. This surface can be a polygon mesh from a CAD model or a high resolution scanned mesh. I require that the mesh be watertight -- that is, closed, consistently oriented and having no significant self-intersections.

My implementation also accepts implicit surface definitions as input. The user provides a bounding box within which the implicit function of the surface should be evaluated.

I will introduce the syntax of my language with several simple examples built from these two polygon meshes.
