Hi- We're interested in using Chimera to prepare POVray files for a movie to be shown on a hemispherical dome. The first part of the movie will be a 360 degree rotation of a DNA/drug complex showing water occupancy around the drug, and the second half will come from an AMBER MD trajectory. We've figured out the content and rendering. The two remaining issues are that the camera must be changed from "perspective" to "omnimax" (fisheye), and the extensive rendering time that will be required for the large system at very high resolution (4096x4096). Here is our plan: 1. Use a command-line script to rotate the system and export the scene to x3d files. 2. Use per-frame scripting in MD movie to export each trajectory frame to x3d files. 3. Use x3d2pov to translate into *.pov files. 4. Change the camera from perspective to omnimax in each .pov file. 5. Render the individual images in parallel on our cluster using povray (different version than the one that ships with Chimera). 6. Compress to jpeg. 7. Assemble movie as .mov (format compatible with projection system in the dome). Does anyone have a better idea? I'm assuming that I can't change the camera to omnimax from within Chimera? Thanks for any suggestions! Kristina -- Kristina Furse Postdoctoral Research Associate 262 Stepan Chemistry Hall Notre Dame, IN 46556 (574)631-3904
