Heightfield Rescale

fields/heightfield-rescale·v1.5.1

IN:1 OUT:1

SUMMARY

Heightfield Rescale builds a new grid over the same extent as the input height field and interpolates every layer onto it, including Height, the falloff and any custom layers. Bilinear filtering is smooth and never overshoots, while Bicubic keeps more detail when increasing the resolution.

Set the new resolution with Resolution Scale or by Grid Samples along the longest side. A typical workflow blocks a terrain out at a low resolution for fast iteration, then rescales up and adds detail with Heightfield Noise or Heightfield Erode.

PARAMETERS

PAGERescale

[+]Division Mode	Divisionmode	Scale multiplies the resolution; By Axis sets the number of samples along the longest axis.
Resolution Scale	Scale	The factor applied to the number of samples along both axes. 2 gives twice the detail, 0.5 half.
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.
[+]Filter	Filter	Bilinear is smooth and never overshoots; Bicubic keeps more detail when increasing the resolution.
[+]Connectivity	Connectivity	Determines the primitive used to connect the points.
[+]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.
