Luma Pictures (luma-pictures.com) has generously donated the project I've been working on to be included in WDAS (Walt Disney animation studio's) Open source PartIO project.
This is an alpha version preview of the plugin we'll be publishing soon.
features may change before beta release and inclusion in the github repo
There are actually 3 parts to the plugin.
1. partioExport command (not demo'd): (a drop in replacement syntax wise) for maya's dynExport command with suppport for all of partio's formats.
2. partioEmitter : a standard maya emitter capable of loading cache data per frame and modifying the particle system its attached to, it basically functions as a "cache emitter" with mapping of partio attributes to maya attributes.
3. partioVisualizer: is a fast, pure openGL locator capable of loading 10s of millions of particles for viewing in maya. Its usefulness includes loading up lidar point data clouds, and previewing caches or other point cloud data partio supports.
