I meant shallow, not acute.

To me it looks like a weird clipping effect

I think this is due to backface culling when the glyphs are inside out - we probably need to flip the glyph polydata based on the sign of the determinant of the transform to world space (or turn off backface culling of glyphs).

I believe this is the same issue that was fixed in slicer3 - maybe it was post-branch of slicer4?

Ron, what dti volume you are using? I could not reproduce this effect on the volume from 2011-08-06-NeuroDti on Win7

I can get all kind of artifacts resizing the slicer window and moving the camera (see attached).
I sometimes get a crash in vtkFrustumCoverageCuller::Cull() on render if I make all slices visible and put glyphs on them and then resize the window.

I am not sure it's because of data or vtk or limits of graphics card...

what is the meaning of scaling for the glyphs? The two images 9-3 at 6pm only differ in the zooming in on the red slice. The third image is after the slice is made visible. This is using the DTI-Brain data set in the sample data collection.

I fixed the original issue:

http://viewvc.slicer.org/viewvc.cgi/Slicer4?view=revision&revision=17981

The issues of glyph sizes after zooming the slice view and corruption of the glyphs after resizing a slice window appear independent.

I created two child bug reports for the other issues.
