Corner Pin Copernicus node

Pins a layer’s corners in a reference layer.

On this page	Parameters Inputs Outputs
Since	21.0

This node directly sets the corner positions of a layer with respect to a reference layer. The corners are specified in terms of the reference layer and the texture layer stretches to go between the corners.

If the reference layer has a perspective camera, use the world position corners to get a perspective transform.

Parameters ¶

Signature

The layer type that the source accepts.

See Signatures for more information.

Units

The space in which to specify the corners. This applies to the size_ref input, which is the reference layer.

Image

Use image coordinates that range from -1 to 1 on the display window of the layer.

Texture

Use texture coordinates that range from 0 to 1 on the data window of the layer.

Pixels

Use absolute pixel locations in the layer.

World

Use coordinates in world space that project through the layer’s implicit camera.

Bottom Left

The lower-left coordinate. The Units parameter determines if this is in image, texture, pixel, or world space.

Bottom Right

The lower-right coordinate. The Units parameter determines if this is in image, texture, pixel, or world space.

Top Left

The upper-left coordinate. The Units parameter determines if this is in image, texture, pixel, or world space.

Top Right

The upper-right coordinate. The Units parameter determines if this is in image, texture, pixel, or world space.

Inputs ¶

size_ref

The reference layer to rasterize the texture into.

texture

The layer with the corners to pin.

Outputs ¶

cornerpin

The layer that’s the size of size_ref with the texture rendered with the corners pinned.
