Kuwahara

Overview

The Kuwahara filter applies a Kuwahara blur to the terrain, which is a different type of blur algorithm that tries to preserve edges lines and high frequency detail. With this it can be used to flatten low frequency areas and create overall more painterly looking straighter shapes.

Parameters

Properties	Description
Kernel Size	The distance of the kernel the filter uses. Higher values means the region for each pixel it operates on is larger.
Passes	The number of iterations the filter runs for each step. Higher values result in a stronger effect.
Anisotropy	Uses edge aligned normals for the sampling algorithm, leading to better edge preservation.
Sharpness	Controls the sharpness of the edge preservation.
Hardness	Controls the hardness between different blurring zones.
Length	Scales the length of the individual edge splats.
Uniformness	Creates more differences between blurring zones.
Zeta	Additional controls for scaling the blurring zones.
