Record camera positions

[aldenkr]

Hi,
I have been trying to record camera positions but sketchyphysics only records one static camera, does not record follow or track cameras. I wish to render animation with twilight,
Sharek made some videos, where he tracks follows and changes positions of cameras, How is this done? I can render animations with scenes with cameras transtions on a fixed moving object but can not follow a moving object. What am I missing? do I need something else?
HELP me please screen capture records everything, properanimation won't record sketchyreplay
any help out there?

There are any number of ways to do this but the most simple is to name two objects trackme and followme and then hide them during the animation if you don't want them to be seen. Then in the scene description type:
camera track trackme. camera follow followme.

This should work. I think this is described elsewhere in this forum and I will try and find those posts but here is a model I put up on Trimble warehouse. One can then just control the location of the camera and target by controlling the location of the two objects. I assume that the "up" position of the camera will remain [0,0,1] but that too could be changed with the script. In this case I use the teleport function on the camera follow object.

Thanks MPTAK! I never knew you could define track and follow in a scene description like that. By putting a 'follow' object on a piston, you can have a camera traverse like a 'dolly' shot. I've always tried doing this by starting the simulation, then assigning track and follow by right-clicking, but this is really much better.
