[Gimp-developer] Motion blur algorithms

[Calculemus <calculemus1988 gmail com>]

I need to implement motion blur(linear, radial and zoom )algorithms
for an app I work on, like yours in GIMP.

In the .c file for motion blur it is not stated which source is used
for the math/algorithm.

Someone knows the source, paper, book or whatever that was
used as reference for implementing the motion blur algorithms?

Thanks
