mask jit.gl.cornerpin

September 6, 2012 | 1:52 am

Hi, does anyone know how to apply an alpha mask to the output of the jit.gl.cornerpin object? I’m currently using cc.alphaglue.jxs before the cornerpin, but I’d like to apply it after the warping.

you could capture as sub-rendercontext with jit.gl.node, then put the captured video into the slab and finally send to a videoplane in your main render context

yup, that’s pretty much what you would do.
the one wrinkle is you lose mouse interaction when capturing a cornerpin to a node sub-context.
the patch below show’s how to toggle between the two modes.

It works except I can’t seem to blend the planes. Any idea why?

took me awhile, but the problem is you forgot the @ sign in your jit.gl.videoplane boxes for the @depth_enable attribute.

Yes that works. Sorry about the oversight….you’re doing a great job on the forum.
