[vtkusers] Point cloud

[Roland Schwarz]

What do you want to do?

Do you simply want to display them as a 'cloud' of pixels?
Rendering is very fast, no need to do much additional things here, but usage
is limited. Quality is bad if looking very close on the obejct because of
the 'holes' between points.

Or do you need to display solid objects?
In the latter case there are a couple of things to do first to get from a
point-cloud to get geometry information.
If you have volume date your course to take will be very different as when
you have data that you know are from a sampled surface.

Some Information on this topic can be found in 'The Visualization Toolkit'
book.
