Houdini 20.5 Nodes Copernicus nodes

Transform 2D Copernicus node

Transforms a layer in 2D.

On this page

This operation transforms a layer in 2D. There are two distinct ways of doing this. The default is to move the pixels by the transform and re-rasterize back on the original layer. The alternative is to just move the layer itself, leaving the data unchanged.

Moving the layer itself allows a series of 2D operations to be done losslessly. To render the result, the Rasterize Layer COP or Project on Layer COP can be used.

Parameters

Signature

The layer type that the source accepts.

See Signatures for more information.

Border

Override the border when rasterizing.

Auto

Use the input border type, unless it is constant, in which case Clip is used.

Constant

Treat the border as zero, with the boundary interpolating to balck.

Clamp

Clamp boundary values steraking them outwards.

Mirror

Reflect along the boundaries.

Wrap

Wrap to the opposite boundary.

Clip

Define an implicit cut off at the boundary without any bleeding of black values.

Filter

The method used to sample the image.

The default value is Box. See Filters for more information.

Mask

The amount of the new value to mix in with the original value. Higher values mix in more of the new value. Lower values mix in less of the new value. You can also set the RGBA channels to which you apply the effects of this node.

The default value is 1, which means this node uses only the new value. See Mask for more information.

Order

Order to apply transforms in.

Translate

The amount to translate the layer in image coordinates.

Rotate

The amount to rotate the layer about the pivot in degrees.

Scale

A non-uniform scale of the layer.

Shear

A XY shear of the layer.

Uniform Scale

A uniform scale of the layer.

Pivot

The pivot used for rotations and scales, defined in image coordinates.

Invert Transformation

Invert the computed transform before applying.

Rasterize

Keep the layer in the same location in space, but re-rasterize its pixels as if it had been transformed.

Inputs

source

The values to transform.

mask

An optional per-pixel mask amount that’s scaled by the Mask parameter.

Outputs

transform

The transformed layer.
