Greetings, Our publications group has a new device that they call a 3D printer. It can make solid models from a data file. They have made models from pdb files as ball-and-stick, and I saw one surface rendered model. They tell me that the input is in VRML. So, I am wondering how to make a VRML file from a session in Chimera where Multiscale Model tool is used to make a surface rendering of a complex model...several proteins. My model is not as complex as the virus examples for multiscale models, but the ability to make different resolution surfaces is a powerful aid. I would like to try and 'print' a 3D model of this surface rendered complex. Any help in out to output the VRML file for the printer?> Thanks Andy -- R.
