Heightfield Terrace

fields/heightfield-terrace·v1.5.1

IN:1 OUT:1

SUMMARY

Heightfield Terrace quantizes a layer of a height field into steps of Step Size, shifted by Step Offset. Smooth Edges sets how much of each step is taken by its riser, from vertical cliffs to a gentle wave, and Fade blends back toward the original.

Limit to Range terraces only between two values, and the falloff restricts the effect to selected areas. Mesa Layer and Cliff Layer write falloffs of the flat treads and the risers, ready for texturing or scattering with other POPX operators.

PARAMETERS

PAGETerrace

Layer	Layer	The layer to terrace.
Step Size	Stepsize	The height of one step in world units.
Step Offset	Stepoffset	Shifts the steps up or down, in world units.
Smooth Edges	Smooth	The part of each step taken by its riser: 0 gives vertical cliffs, 1 a gentle wave.
Fade	Fade	Blends back toward the original layer. 0 gives full terraces, 1 has no effect.
Limit to Range	Limitrange	Terraces only the values between Minimum and Maximum.
Minimum	Rangemin	The lowest value terraced.
Maximum	Rangemax	The highest value terraced.
Mesa Layer	Mesalayer	When set, writes 1 on the flat treads of the terraces into this layer (a falloff).
Cliff Layer	Clifflayer	When set, writes 1 on the risers of the terraces into this layer (a falloff).
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.
