By popular demand, here is a .ply polygon/pointcloud reader (supporting both ascii and binary files):
nuget install vl.io.ply -pre
Due to the flexible nature of the format, not all possible cases can be supported out of the box. So for now this reads XYZ and RGB components and faces. If your need other info than that from a file you’ll have to implement your own of the adaptive “AsciiVertices” and “BinaryVertices” operations.
Please let me know if you stumble on a file that doesn’t load correctly!
