Detailed Description

A visual representation of a set of points.

Displays a set of points using any number of Ogre BillboardSets. PointCloud is optimized for sets of points that change rapidly, rather than for large clouds that never change.

Most of the functions in PointCloud are not safe to call from any thread but the render thread. Exceptions are clear() and addPoints(), which are safe as long as we are not in the middle of a render (ie. Ogre::Root::renderOneFrame, or Ogre::RenderWindow::update)
