Houdini 21.0 Nodes Copernicus nodes

VDB Leaf Points Copernicus node

Creates a point for each active leaf in a VDB.

On this page
Since 21.0

This node will create a point for each active leaf in the incoming VDB. A leaf is an 8×8×8 block of voxels. Since these points will have a 1:1 correspondence with the VDBs topology, they can be used to in geometry-based operations.

Note

The order of leaves within a VDB is not deterministic, so the order of points created from this should not be relied upon.

Parameters

Set Positions

Sets the P attribute of the point to the center voxel of the leaf.

Point Attributes

Additional point attributes can be created so they are available in later OpenCL nodes.

Name

Name of an extra attribute to create.

Class

The classification of the point attribute. Since only points are created, only the Detail and Point choices are directly applicable, but the others are provided for completeness.

Type

The type of attribute to create, either integer or float.

Tuple Size

The tuplesize of the attribute.

Inputs

vdb

A VDB for each each active leaf will create a point.

Outputs

points

A Geometry point cloud with one point per active leaf in the VDB.
