  Inverse Camera Z Orientation expression …. ?

  Posted by Tim West on December 14, 2011 at 2:35 pm

  Hi,

  I’m trying to write an expression which parents a some text to the inverse of a cameras Z orientation (not Z rotation).

  To explain – I have a camera which zooms in and out of various compositions and would like to sit some text in these scenes – whilst I want this text to exist in the 3D space I’d like it to remain level at all times (e.g. not be affected by the cameras Z rotation).

  Any help on how to achieve this would be appreciated!

  Thanks,

  T

  Try this:

  c = thisComp.layer(“Camera 1”);
  v = c.toWorldVec([1,0,0]);
  radiansToDegrees(Math.asin(v[1]))
