Analytical computation, as an instrument to generate geometry and evaluate its ‘performance’, is inherently dependent on ‘meshes’ or node based geometry. The attempt on this short-term research was to understand the functioning of node-based geometry, text-based polygon file formats, types including Delaunay , Voronoi, half-space intersections, convex hulls etc.

In view of the lack of access to Maya's internal triangulation engines, the research concentrated on wrting simple translators to access external, command-line executables such as qhull,tetgen and surface evolver.Tetgen has so far proved to be most useful, in that it can be compiled into either an executable or a dll. ie. supports both standard MEL 'system' calls and c++ api calls from within Maya plugins. Further, tetgen also supports constrained delaunay triangulation.

Although resulting triangulated meshes do not support regular poly-modelling workflows, they provide interest as reference objects.They are also useful in geometric problem solving, eg: prim's algorithm.
