SUMMARY

Heightfield starts a height field chain. It lays out a grid of samples at the cell centers of a rectangle of a given Size and Center in the ZX, XY or YZ plane, gives every sample an Initial Height, and outputs a POP with Height, normals and the orientation, optionally with Tex and a falloff layer.

Division Mode sets the resolution by Grid Spacing in world units or by Grid Samples along the longest side, and Connectivity builds triangles, quads or points only. The Slope, Gradient and Curvature toggles add derived layers that every height field operator downstream keeps up to date, ready for Heightfield Falloff, scattering or shading.

PARAMETERS

PAGEHeightfield

[+]Orientation	Orient	The plane the height field lies in. Height is measured along the plane's normal axis: Y for the ZX plane, Z for XY, X for YZ.
Flip Up Direction	Flipup	Measures Height along the negative axis instead, so the terrain faces the other way.
Size	Size	The width and length of the height field in world units.
[+]Center	Center	The position of the height field. The component along the up axis raises or lowers the whole terrain: it is added to the Height.
[+]Division Mode	Divisionmode	By Size sets the sample spacing in world units. By Axis sets the number of samples along the longest axis; the other axis follows the aspect.
Grid Spacing	Gridspacing	The distance between two samples, in world units.
Grid Samples	Gridsamples	The number of samples along the longest axis.
Resolution	Resolution	The resulting number of samples along each axis (read only). Limited to 1280 by 1280 samples with a Non-Commercial license.
Initial Height	Initialheight	The starting height of every sample.
Add Falloff Layer	Addfalloff	Adds a falloff layer to the height field.
Initial Falloff	Initialfalloff	Sets the starting value of the falloff layer.
[+]Connectivity	Connectivity	Determines the primitive used to connect the points.
Texture Coordinates	Texcoords	Adds a Tex attribute that runs from 0 to 1 across the height field.
Gradient Layer	Computegradient	Adds a Gradient layer (the rate of change of Height along the plane). Every height field operator downstream keeps it up to date.
Slope Layer	Computeslope	Adds a Slope layer (the steepness in degrees). Every height field operator downstream keeps it up to date.
Curvature Layer	Computecurvature	Adds a Curvature layer (positive in valleys, negative on ridges). Every height field operator downstream keeps it up to date.
[+]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.
