A question concerning IDLgrTessellator:
I currently work with models of irregualar bodies (asteroids), these
models consisting of a set of vertex cordinates and a plate-vertex
assignment map. The IDL IDLgrPolygon facility greatly eased data set
display and manipultation. While my data currently includes the
plate-vertes map, I'd find it convenient to generate this map from the
vertex coordinates.
I attempted to create a map using only vertex data passed to the
IDLgrTessellator object, but failed. The Tessellate method did produce a
map, but the plates tended to pass through the body instead of a more
nearest-neighbor configurations.
I suspect I lack a complete understanding of IDLgrTessellator. Can
anyone provide some pointers, or is this an inappropriate application of
the tesselation function?
As always,
Ed Wright
