plyo

this is a cli tool that optimizes pointcloud files.

converts:

precision

• x, y, z and nx, ny, nz get reduced in precision (default: 3, 0.001, 1mm)

removes alpha

• alpha gets removed if all alpha values are 255

removes normals

• if the --remove-normals flag is used, nx, ny and nz get removed. (useful when your engine lets the faces look at your camera)

merge duplicate points

• merges colors of points at the same location (with 0.001, 1mm precision).
