/* This shader computes indirect diffuse and stores it into a point cloud.

Created by: Jorge Pimentel - http://blog.jorgepimentel.com to use with 3Delight

Attributes:
intensity - The intensity of the indirect diffuse calculation
samples - number of samples
ptcPath - path to the point cloud to be written
interpolate - 1 to interpolate, 0 to not interpolate. When set to 1.0, it saves the center of the micro-polygons and not its corners.
This is useful for point-based indirect diffuse
