To Smooth a
texture is one of the standard filter operations that you can find in all
image editors. It works by averaging each pixel with its neighbors. This
results in a blur effect.
The only attribute
of the smoothing effect is its radius. It defines the number of
neighbors, that are employed for the calculation of the result.
Neighbors, that are nearer to the target pixel, have a greater
influence to the result.
valence curve is given by the gaussian bell function.
Utilize the Mixing Mode
within the Mixer
to achieve a number of useful effects with the Smooth function.
For example the mode "Add" will give you a
"Dream Scape" effect. "Darkest" results
in erosion, "Lightest" in a glow effect.
