Dear X11 Users,

After the latest Mac update, I noticed a bug with rendering vtk data embedded in gtk windows. If I try to render a vtkVolume and a vtkActor, the vtkVolume is not displayed. This does not happen if the vtk window is not embedded in a gtk window. It also doesn't happen when using the same versions of vtk and gtk on a under Linux with a Linux display. It does happen if I ssh to a Linux box and display on the Mac, which is why I suspect that X11 is a part of the bug. (I was unable to check whether the bug appeared when running on a Mac but displaying in Linux as this resulted in a bus error.)

Here are the details of the latest Mac updates

2009-06-09 13:14:35 -0400: Installed "Digital Camera Raw Compatibility Update" (2.6) 2009-06-09 13:14:50 -0400: Installed "AirPort Utility Software Update 2009-002" (5.4.2) 2009-06-09 13:15:07 -0400: Installed "iWork '09 Update 2" (9.0.2) 2009-06-09 13:15:49 -0400: Installed "iTunes" (8.2.0) 2009-06-09 13:15:53 -0400: Installed "iLife Support" (9.0.3) 2009-06-09 13:16:07 -0400: Installed "iDVD Update" (7.0.4) 2009-06-09 13:18:54 -0400: Installed "Mac OS X Update" (10.5.7) 2009-06-09 13:19:26 -0400: Installed "QuickTime" (7.6.2)

The relevant version info is:
X11 2.3.3.2
VTK 5.0.4.3 (fink package vtk-py25)
GTK 2.16.2-2 (also installed with fink)
pygtk 2.12.1-5 (also from fink)
Python 2.5 (fink package number 1:2.5.4-1)

I've posted test scripts, data, and pictures here: http://www.ctcms.nist.gov/oof/renderingbug/

Any insights are greatly appreciated!

Thanks
Valerie Coffman
