[Bf-committers] Request for feature: colored point clouds

[Aurel W.]

Hi,

+1 from me. I would also need such features asap. But I would go a
little bit further than just colored vertices. It would be great to
introduce pointclouds as a new object type.

Maybe later on blender can make also use of libpcl for modifiers on pointclouds.
