Houdini 21.0 Nodes Copernicus nodes

Space Transform Copernicus node

Transforms positions and UV values between spaces.

On this page
Since 21.0

This node transforms position, vector, and UV values between different camera spaces. The values of the layer or VDB are transformed, using either the camera of the coord input or the reference cameras (if wired).

Parameters

Signature

The layer type that the source accepts.

See Signatures for more information.

Vector Type

How to transform the vector values.

Position

Translate, rotate, and scale position values.

Vector/Displacement/Velocity

Rotate and scale vector values.

Source Space

The space in which the original values are assumed to be. This relates to the src_ref if wired, otherwise the coord input.

See Spaces for more information.

Buffer

The index with respect to the actual raw data. This may differ from Pixels if running with a pixel scale.

Pixel

Pixel indices, which are unaffected by pixel scale.

Texture

A 0 to 1 value within the data window of the layer.

Image

The unstreteched -1 to 1 position within the fitted display window.

World

The location in world space.

Destination Space

The space into which to transform the values. This relates to the dst_ref if wired, otherwise the coord input.

See Spaces for more information.

Inputs

coord

The UV layer, RGB layer, or vector VDB that provides the coordinate values to transform.

src_ref

An optional reference for the camera in which the values are initially. If unwired, the node uses coord.

dst_ref

An optional reference for the destination camera. If unwired, the node uses coord.

Outputs

transform

The input coordinates transformed into the new space.
