We are about to switch to a new forum software. Until then we have removed the registration on this forum.
I am a processing beginner and wondering how achieve the following, assuming it is even possible on processing. I am not looking for implementation solutions, but much rather pointers on how to approach this and if it is possible.
The sketch should be running on a internet connected (static IP can probably be arranged) remote computer with a webcam. What I want to do is send some sort of request to that computer from a webserver to make it take a image.
Taking a picture with the webcam is something I can most likely figure out from tutorials, but how can I listen for remote calls to take a picture (or do anything, for that matter)? The computer running the sketch can be anything, really, but let's assume some sort of Unix machine.
