Filter

public Filter(IGLApi glApi,
              Filter.Kernel kernel,
              int kernelSize,
              int samples,
              int numComponents,
              boolean log,
              java.lang.String sampleFunc)

Parameters:

gl - OpenGL Context

kernel - blur Filter.Kernel

kernelSize - blur filter size

samples - multi-sampling factor. If > 1, filter and filterSize will be ignored.

numComponents - number of component to blur

sampleFunc - optional sample function to modify input sample value (#SAMPLE#). Usage example: "vec2(#SAMPLE#.x, #SAMPLE#.x * #SAMPLE#.x)"
