Import Point Cloud
The Import Point Cloud button displays a dialog to import a point cloud from another
application. Supported filetypes are:
Alias's Maya .ma
3DS Max ASCII Scene Export .ase
NewTek's LightWave .lws
Softimage XSI's .xsi.

can be found in “The Common Controls” section at the end of this chapter.

menu with several options that make it simple to locate, rename, and separate these points from
the rest of the point cloud. The contextual menu contains the following options:
