Position Map Copernicus node

Generates a Position Map.

On this page

This operation generates a Position Map. This is an RGB layer where each pixel represents a location in 3d space. This can then be used as the reference location for noises such as Fractal Noise 3D.

The effect of this operation is to store in each pixel its position in 3d space.

Parameters

X Border

The canonical 3d shape is cube with sides of size 2. The border controls how values outside this cube are mapped. This allows for the formation of periodic values.

Clamp

Clamped to the nearest side of the cube.

Mirror

Reflected about the boundary of the cube.

Wrap

Take the value of the opposite side of the cube.

Extend

Unaffected by the cube.

X Shift

Additive adjustment prior to the border correction.

X Cycles

Scale applied prior to the border correction. When wrapping is enabled, effectively becomes a cycle-count.

Y Border

The canonical 3d shape is cube with sides of size 2. The border controls how values outside this cube are mapped. This allows for the formation of periodic values.

Clamp

Clamped to the nearest side of the cube.

Mirror

Reflected about the boundary of the cube.

Wrap

Take the value of the opposite side of the cube.

Extend

Unaffected by the cube.

Y Shift

Additive adjustment prior to the border correction.

Y Cycles

Scale applied prior to the border correction. When wrapping is enabled, effectively becomes a cycle-count.

Z Border

The canonical 3d shape is cube with sides of size 2. The border controls how values outside this cube are mapped. This allows for the formation of periodic values.

Clamp

Clamped to the nearest side of the cube.

Mirror

Reflected about the boundary of the cube.

Wrap

Take the value of the opposite side of the cube.

Extend

Unaffected by the cube.

Z Shift

Additive adjustment prior to the border correction.

Z Cycles

Scale applied prior to the border correction. When wrapping is enabled, effectively becomes a cycle-count.

Inputs

size_ref

A representative layer that determines the size of the output image and controls the metadata.

Outputs

pos

An RGB layer providing the 3d-coordinates of each pixel.
