spider volumes look incomplete or sliced. Version Linux SUSE 10.2
Im having a problem with the latest Chimera version, as well as previous ones for linux2 platform. When loading spider volumes they are imcomplete and sliced. Anyone have any suggestions? A much older version build 2470 from 2007/11/15 runs just fine. Thanks.

Hi Tim, We have seen this before. It is a bug in the old Mesa OpenGL library that comes with your Linux distribution. The bug is specifically in the use of a high performance OpenGL feature called vertex buffer objects. The solution is to install a graphics driver from the video card manufacturer (nvidia or ati/amd). This will also give 10x to 100x faster rendering because the manufacturer driver will use hardware acceleration where Mesa does all graphics calculation in software. See our graphics driver bug web page for more details. http://www.cgl.ucsf.edu/chimera/graphics/graphicsbugs.html This bug is not specific to SPIDER maps and will effect all Chimera surfaces. It did not occur in old Chimera versions which used older lower performance rendering methods. Tom booth@wadsworth.org wrote:
