Hi, I’m trying to do a spherize filter in imaging Lingo, but i got stuck on the math… What I’ve got so far using the formula I found here: www.eng.iastate.edu/ee528/Projects/Project1-s2001/results/gtkavithachen.doc
polarOrigin = sqrt(power(sourceX,2) + power(sourceY,2)) Ro = centerX / (1/2 * (1 + (cos(angle / 2) / sin(angle / 2)))) R = Ro / (sqrt(sin(angle / 2))) polarDest = centerY + sqrt(power(R,2) - power(polarOrigin - centerX , 2)) The problem is I can't get the destination X and Y out of this... Anyone have a clue? Thanks, Chris.
