Houdini 21.0 Nodes Copernicus nodes

Lattice Deform Copernicus node

Applies grid-based deformation to a layer.

On this page
Since 21.0

This node lets you apply grid-based deformation to an image. The Lattice parameters determine how many grid points the layer has, which corresponds to how many handles there are. Turn on the Handles tool to transform the grid points of the image in the viewport instead of in the parameter editor.

This node provides more detailed deformation than the Bend COP. You can use the Bend COP instead of this node when you want to simply and quickly deform an image.

Parameters

Signature

The layer type that the source accepts.

See Signatures for more information.

Image Mesh

Mode

The interpolation method to use between the grid and image.

Linear

The deformation follows the grid exactly.

Smooth

Use non-uniform rational b-spline (NURBS) interpolation to produce fluid deformation across the grid.

U

The point density in the U-direction when NURBS curves convert into polygons.

V

The point density in the V-direction when NURBS curves convert into polygons.

Lattice

Cells per Column

The number of grid cells in each column. This value is always one less than the Columns value.

Columns

The number of columns in the grid, which are represented by vertical lines. This value is always one more than the Cells per Column value.

Row #

The number of grid points in the row. The leftmost points correspond to Point #_0.

Use the tab menu to configure the grid points for a row. For example, click the 0 tab to configure the row along the bottom of the image.

Point #_#

The position in image space of the grid point. This represents a handle in the viewport.

Inputs

size_ref

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

source

The source layer to deform.

Outputs

deform

The layer with deformation applied.
