Houdini 21.0 Nodes Copernicus nodes

Layer to VDB Leaf Points Copernicus node

Creates a point for each leaf of a VDB that would be in an envelope.

Since 21.0

Three Mono layers define an envelope in world space. The thickness layer is how thick the envelope is, the height is the displacement from the imaging plane of the layers, and the density controls if it is present there or not.

For potential leaf in the reference VDB that would touch the envelope, this node creates a point. This can be used then to activate the VDB to ensure all voxels in the envelope are activated.

Parameters

Thickness

A global scale on the thickness input, allowing a 0-1 layer to be rescaled to world units.

Inputs

refvdb

The reference VDB, only its transform voxel size is used.

thickness

A Mono layer specifying how thick the envelope is at each pixel.

height

A Mono layer specifying where the envelope’s center line will be, as measured from the layer itself.

density

A Mono layer specifying the alpha of the envelope, zero areas will not generate points.

Outputs

points

Geometry point cloud output consisting of points at the center of any potential leaf that touches the envelope.
