Python script that creates Maya Particle Disk Cache (PDC) files from a sequence of point cloud data, and also gives you the choice of importing a single point cloud. It could be useful with all the open source data being released from Kinect hacks or 3D scanners. You can start by playing around with Radiohead's House Of Cards data:
You can’t perform that action at this time.
