I am aware of that, the simplest is to just draw the points. He hasn't 
asked about anything like that, he specifically asked for mesh or 
"wireframe" output, and seems to believe that having points on the 
surface automatically means you have a mesh. Unless you are going to use 
some kind of volumetric rendering, point clouds can not be raytraced 
without first being processed into a mesh or some other object. This 
processing is difficult, and the resulting surface doesn't always match 
the original very closely. Point cloud data won't be of much help for 
any of the things he has asked about, especially the partial data you 
would get from the first intersections.
