<p>Chimera generates POV-Ray input by converting it's X3D output to
POV-Ray with the CHIMERA/bin/x3d2pov program. x3d2pov is tailored
for Chimera's X3D output, but it will probably work with
ChimeraX's X3D output. To use it, run:</p>
<p> CHIMERA/bin/x3d2pov -o FILENAME.pov < FILENAME.x3d</p>
<p>where CHIMERA is the location where Chimera is installed and
FILENAME is the name of the data file.</p>
<p>One caveat about ChimeraX's X3D output, most X3D viewer's blindly
apply the unit node's conversion factor to scale the coordinates,
which results in nothing to see. The unit node is supposed to
have no effect in the case of a single X3D file, but in practice
it does. So to view the data, remove or comment out the unit
node.</p>

<span>ChimeraX is a different program than Chimera, being
built from the ground up. So any differences are not the
result of “removal” per se, and may still be planned for
future implementation. However, we do not plan for the
programs to be identifical, and I don’t know of any hard
decision (either way) as to whether povray export will be
included. Currently ChimeraX has directional shadows
similar to the option in Chimera, and “ambient-occlusion”
multishadowing, which was not available in Chimera.
</span><br>
<span></span><br>
<span>There may be an intermediate solution:</span><br>
<span></span><br>
<span>In Chimera, the povray export is by making an initial
X3D file and then running the x3d2pov conversion program
included with Chimera (in the bin directory). </span><br>

<span>ChimeraX does have export to X3D implemented (command
“save” with “format x3d”), so maybe you could do that and
then “manually” run the conversion program mentioned above.</span><br>
