  3d flair emulation

  Posted by Nicholas Toth on October 6, 2006 at 3:19 pm

  So by using Dan’s script a few weeks back of

  L = thisComp.layer(“3d Flair Controller”);
  L.toComp(thisComp.layer(“3d Flair Controller”).effect(“Point Control”)(“Point”))

  To control a lenseflair on a 3d layer with a pointer expression on it has been very sucessfull.

  I’m trying to figure out now how to link the distance of the 3d object (from the camera) with the intensity of the flair,
  the farther away the more faint the flair, and the closer the flair to the camera the more intense it becomes.
  I really don’t know where to start, but any suggestions would be very helpful.

  Try this:

  
  cam_pos=thisComp.layer(“Camera”).position;
  layer_pos=thisComp.layer(“Flare Layer”).position; //replace with object or create dummy layer

  far_pos=10000; //farthest distance
  near_pos=20; //closest distance

  near_int=3; //intensity at near point
  far_int=100; //intensity at far point

  distance=length(cam_pos,layer_pos);

  flare_int=linear(distance,near_pos,far_pos,near_int,far_int);

  [flare_int]

  Its not exactly how I imagined it, but I picked your code apart and got it to work.
  Thanks!
