Did anybody ever tried to interface ROS with Blender? In particular I would be interested in using blender via the command line and triggering it to render a scene and updating it via a rosrequest or rostopic. For any information on how to do that, I would be very thankful.
Should be totally doable. Regardless of Blender, Python has APIs for networking, which is how you usually talk to ROS. The only problem I can foresee is that Blender + Python cannot currently do concurrency, meaning that if the view-port is being laggy, your code won’t be able to run as fast or often as you might need it to.
