Heightfield Measure

fields/heightfield-measure·v1.5.1

IN:1 OUT:1

SUMMARY

Heightfield Measure computes the steepness in degrees, the gradient along the plane and the curvature from the height differences of a height field, and writes them as the Slope, Gradient and Curvature layers.

Once added, these layers stay up to date: every height field operator after this one refreshes them, so falloffs, scattering and shading can read the terrain's shape anywhere down the chain. Border sets how the edges are read.

PARAMETERS

PAGEMeasure

Slope Layer	Computeslope	Adds a Slope layer: the steepness in degrees, from 0 for flat to 90 for vertical.
Gradient Layer	Computegradient	Adds a Gradient layer: the direction and rate of the steepest ascent along the plane, in world units per world unit.
Curvature Layer	Computecurvature	Adds a Curvature layer, per world unit: positive in valleys and creases, negative on peaks and ridges.
[+]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.
