Display Lists are not being properly generated and called during polygonal mesh rendering.
This issue was created automatically from an original Mantis Issue. Further discussion may take place here.
Using ParaView 3 from CVS (and also the 3-1-0 branch) attempting to render polygonal meshes results is low framerates. This can be reproduced by creating a sphere source and setting the phi and theta resolutions to 1024. This will create a sphere with about 2 million triangles. Interacting with this sphere will produce framerates of about 1 frame per second. Using "OpenGL Profiler" on OS X seems to show that the display is being created but never called as evidenced by the number of calls to glFloat3fv and glNormal3fv while glCallList is never called even when immediate mode rendering is OFF. This same test under ParaView 2.6.1 produced framerates of 25 to 30 FPS. LODs thresholds were turned OFF on all machines and versions of the programs.
