User heime has pushed new remote branch:

bug-19225-pointsetrendering

TODO:

• Property Observer to switch the rendering modes on demand
• Point selection color
• Labels (are the old ones, maybe not used anymore)
• Rendering lighting artefacts created by vtk

Actual behavior

Rendering a pointset with about 5000 points is very slow. Making the GUI nearly unusable.

Expected behavior

Normal rendering performance should not be affected so much by something trivial like points. It should be possible to render more than 1.000.000 points in realtime without affecting the user experience.

Cause of the bug

The points are rendered with vtk spheres that are incredibly slow.

Proposed solution

Add a property to render the point set as gl points on demand.

Affected classes

mitkPointSetVtkMapper3D.cpp

How will the bugfix get tested?

Manually tested with release checklist.
