Plane Tracking a Point Keeps Disappearing
Messing about with Voodoo to track some points, I thought I'd attach a plane to one of them. But it flickers off at some positions.
The plane's outline is still there, so it's on screen, and the point it's tracking is certainly still there, and it doesn't go behind the image (which is 2D anyway) so I'm stumped.
Anything I should be doing differently?
