points module

Warning! EXPERIMENTAL:

these features and functions are under development, will have bugs, and may be heavily modified in the future

Tools for importing and working with point clouds - OBJ loader, requires pywavefront - PLY loader, requires plyfile - LAS loader, requires laspy

These functions ported from my viz script repo here: https://github.com/mivp/vizscripts/tree/master/pointcloud More tools can be found there, including a ptx reader which handles transformations of multiple point clouds into one coord space

Module Summary
