[Chimera-users] shininess/brightness/specular color of surfnet surfaces
Hi, Is it possible to alter the shininess/brightness/specular color of Surfnet surfaces? Also is it possible to save the surfaces so they don't have to be recreated every time? Thanks, ----------------------------------------------------------------- Sabuj Pattanayek Martin Egli Lab Vanderbilt University Dept. Biochemistry http://linegli.mc.vanderbilt.edu
Hi Sabuj, The Surfnet surfaces are handled in Chimera as VRML (Virtual Reality Markup Language) models. The shininess control does not work on VRML models. Also session saving does not save VRML models so they need to be recreated each time you use Chimera. We have been using VRML models in Chimera less and less because they do not support some basic capabilities as you have found. We have another type of surface model used for displaying volumetric data (isosurfaces). To fix the lack of shininess control for Surfnet surfaces, we probably should make Surfnet use the other type of surface model instead of VRML. That will require us to write some new code. Even with that change you still won't be able to save the surfnet surface -- it will still need to be recomputed. Tom
Hi Sabuj, Tom's comments about shininess are correct. However, we may in fact implement saving of VRML models. Probably in the next release or two. Eric Pettersen UCSF Computer Graphics Lab pett@cgl.ucsf.edu http://www.cgl.ucsf.edu On Sunday, January 4, 2004, at 11:57 AM, Thomas Goddard wrote:
