Orbiting a camera with Field of View and LookAT

volkerk's picture

I'm getting some odd behavior if i combine the look At patch to position a GL camera (orbiting around an object) with a Field of View patch. The attached composition demonstrates that. The left cube has field of view patch, the right one not. Any ideas anybody?

GL Look At is a private patch -- we're trying to tweak its behaviour before making it public. Right now it doesn't play nicely with most other patches (including FoV).

Sorry for popularising that patch with the Random Walk compositions. I didn't realise it was private at the time.

no worries! we include it because we figure someone will be able to do something cool with it -- we just aren't personally satisfied with its functionality right now, so we're not making it official.

your Random Walk composition is one of the most fascinating compositions I've seen in a while, and it caused me to look at many things because of it (including higher-performance structure methods, javascript, and the Look At patch itself).

Wow, thank you for the compliments, cwright- they mean a lot, coming from you, especially since without you and smokris work, a lot of what I do in Quartz Composer wouldn't be possible. It's heartening to know that inspiration works both ways!
