vtkGlyph3DMapper does not allow re-use of glyph sources
This issue was created automatically from an original Mantis Issue. Further discussion may take place here.
vtkGlyph3DMapper does not allow you to switch among multiple sources, using SetSourceConnection. You can switch once, but after that, it does not render the correct source.
Sample code that demonstrates the issue is attached. To expose the issue, #define REUSE_SOURCES. If you don't define that, the rendering is correct.
The workaround, as demonstrated in the sample, is to recreate the glyph sources each time you want to switch glyphs. But this should be unnecessary and could potentially be expensive.
