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

• 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 (Use Zeta enabled)

  Additional controls for scaling the blurring zones.
