The SavePOV
command creates an input file for PovRay (www.povray.org
) to calculate a ray-traced view of the scene with realistic shadows.
When compared to the image on screen, the PovRay scene has the following shortcomings:
- The fog is missing.
- The background colors may not be displayed correctly.
- Images shown in the fore- and background are missing.
It is therefore suggested to use the RayTrace
command instead, which does not only run PovRay directly, put also postprocesses the PovRay output to include the missing features listed above.
Look in the getting started section
for instructions how to install PovRay.
Many additional hints and notes can be found at the
RayTrace command.
Example 1:
SavePOV 1crn,1.2,Atoms=Blobs
Save a scene description for PovRay as pov/1crn.pov or 1crn.pov is subdirectory pov is not present,
with all atoms 1.2 times the usual size, displaying all balls as smooth blobs.
Example 2:
SavePOV 1crn,1.2,Atoms=Balls,LabelShadow=yes,SecAlpha=50
As above, but show atoms as normal balls, let labels cast shadows,
and show secondary structure half transparent.
