[Visualpython-users] proposed mesh object

[Ari H. <ahe...@an...>]

Playing with Scherer's Mesh class based on the faces object, I realized that
drawing heightfield meshes might be a pretty common application. Right now
faces is extremely poorly optimized for this (using the Mesh class anyhow):
vertices are not correctly shared between polygons, and setting up the mesh
from the data is extremely slow (since it turns the Mesh into polygons one
vertex at a time in Python, for a 30x30 Mesh that's 900 polys and 3600
vertices in the inner loop.

This was by far the most expensive part of a heightfield demo I wrote; by
comparison calculating fractals heightfield data is very cheap.

A mesh object would be pretty easy to write that took a rectangular x 3
matrix (i.e. a rectangular matrix of vectors). This would be faster to
render as well as faster to construct.

Any thoughts/requests?
