Scalar Data Assignment: Forward vs Backward interpolation - accidental_PhD - 11-13-2014 11:22 AM

A few people have had this problem, so I thought I should comment on it here.

Remember for bilinear interpolation, you should iterate over the target pixels (the image you're trying to create), and map those positions back to the source image - then it's easy to figure out which four points you should use to interpolate.
