toComp “according” to another camera
Is there any way to do this ?
toComp converts according to the active camera, but I want to know the coördinates as another camera would see them.
The only workaround I can think of is to store all the properties of the other camera in keyframes in negative time and use that time in the toComp();But perhaps, there’s a clever Vector/Matrix/Layerspace way to do this an other way.
As usual, my vector Math is letting me down…Dan ?

I can’t think of an easy way to do it. You’re really projecting a point onto a plane representing the view of the other camera. Of course, that’s what toComp() does for you with the active camera. I found some references on how to do the projection, but it doesn’t look like fun. Just curious – why do you want to do this?

Working on a poor man’s camera mapper using powerpin unstretch.
I have it working for 1 camera where the setup is at time is zero, but want to set it up with a projector camera.
I’ll prob do It via a script so I can use the negative time trick.
