Heightfield Blur

fields/heightfield-blur·v1.5.1

IN:1 OUT:1

SUMMARY

Heightfield Blur filters one layer of a height field over a Radius in world units, so the result does not change with the resolution. Blur and Box Blur average the neighborhood, Expand and Shrink take its maximum or minimum, and Sharpen pushes the layer away from its blurred copy.

Iterations repeat the filter for a softer, wider result. Pick Height to smooth the terrain or a falloff layer to grow, shrink or soften the falloff; the falloff blends the effect, and Falloff Aware Radius scales the radius by it so the blur fades out without a seam.

PARAMETERS

PAGEBlur

Layer	Layer	Selects the layer to blur: Height smooths the terrain, a falloff layer softens the falloff.
[+]Method	Method	Blur and Box Blur average the neighborhood, Expand takes its maximum, Shrink its minimum, Sharpen pushes the layer away from its blurred copy.
Radius	Radius	The size of the neighborhood in world units. It does not depend on the resolution.
Iterations	Iterations	Repeats the blur. Four iterations blur about as much as doubling the Radius, with a smoother falloff.
Sharpen Strength	Sharpenstrength	How far Sharpen pushes the layer away from its blurred copy.
Falloff Aware Radius	Falloffaware	Scales the Radius by the falloff attribute too, so the blur fades out without a seam at the falloff edge.
Do Falloff	Dofalloff	Weight the effect on each point by the Falloff Attribute.
Falloff Attribute	Falloffattr	The point attribute, 0 to 1, that weights the effect.
Invert Falloff	Invertfalloff	Uses one minus the falloff attribute.
Falloff Strength	Falloffstrength	Scales the effect of the falloff attribute.
[+]Border	Border	Determines how samples outside the height field are read at its edges. Streak repeats the edge value, Constant uses Border Value, Repeat wraps around.
Border Value	Bordervalue	The height read outside the height field when Border is Constant.

PAGECommon

Bypass	Bypass	Pass through the first input to the output unchanged.
Free Extra GPU Memory	Freeextragpumem	Free memory that has accumulated when output memory has grown and shrunk.
