Changing Boundaries

[icecapsule]

Hi, I'm using your projection mapping software on a Mac and would like to project a shape that then evolves and gets smaller (in relation to an object in a video). Is there a way I can move the boundaries throughout the video? Also, is there a way I can sort of attach the boundaries to an object so they change as the object changes? It's just a rotating pyramid, so it's no too complicated a shape and has straight edges rather than curves.
Thanks, Claire

Hey Claire, welcome first of all...

Sounds like you want to set up some type of mask on a layer above your video, and then control the size of it via hotkey, be it keyboard, MIDI or OSC, preferably the last two...
