A point cloud is a set of data points in space. Point clouds are generally produced by 3D scanners, which measure a large number of points on the external surfaces of objects around them.
Point clouds are supported on Sketchfab in some formats such as PLY, DXF, ASC (text), VRML, OBJ, 3DC and LAS.
ASCII text files should be formatted with one vertex per line, optionally with RGB color information:
x y z r g b
This is identical to the XYZ format, which can be uploaded by renaming ".xyz" as ".asc"
We process point position and color, but we do not currently support other flags in the file like point size.
You can set a size for all points in 3D Settings.
