  • Connecting corners of elements in 3d space

    Posted by Dominic Tremblay on March 13, 2009 at 9:56 pm

    I’m trying to find a way to connect the corners of 2 elements in a 3d environement. The camera is animated, and the anchor point of the elements as well. I tried creating a solid then parenting it to one of the elements and using the lookAt fucntion to look at the seconde lements but I need it to lookat the corners of the object not center, and also because the anchor point is animated it’s a bit off….Can anyone help.

    Could you do it with a 2D Beam effect set up on a solid over the 3D layers ?
    Then you’d add some point controls on the corners of the two layers, and use layerSpaceTransform to calulcate the values of the beam.

    This has been discussed often before: do a search for “toComp(” or “layer space transform”
