To export 3D data from chimera, you either (a) need a chimera window (can be minimized) or (b) need to use the headless version of chimera (only available for Linux). On the command line, if you export to a file that is named with a .html suffix, it will use WebGL, e.g., export filename.html From Python: from chimera import exports exports.doCommand('WebGL', 'filename.html') We still consider the WebGL support experimental, and it has problems with large structures, but please check it out.

Dear Chimera Team,

I was curious if there was a functionality to export chimera scenes to webgl through the command line, without having to open the chimera window. Is there a set of python script commands that would do it?

Thank you for your support, Thomas
