Houdini 21.0 Nodes Copernicus nodes

Invoke Geometry Copernicus node

Runs a program saved into geometry using inputs plugged into this node.

On this page
Since 21.0

This node runs a program saved in a geometry on inputs plugged into this node. Use the Block to Geometry COP to generate program geometry from a block, and then wire that program into this node.

Parameters

Iterations

The number of times to run the program, with outputs feeding back as inputs into the subsequent iteration.

Note

This node can repeatedly run the program only when its outputs can be converted into the respective inputs (matched by index). Otherwise, this node performs a single iteration and sends a warning.

Set Inputs and Outputs from Incoming Program

Sets up this node’s input and output ports to match the incoming program. This populates the Inputs and Outputs multiparameters using the program’s signature.

Inputs

The number of this node’s input ports, which are based on the Block Inputs of the Block Begin COP that generated the program geometry.

Input Label

The name of the program input to bind the respective incoming layer to. This is matched against the Input Name values on the Block Begin COP that generated the program geometry.

Input Type

The data type of the input and the corresponding port on this node.

Outputs

The number of this node’s output ports, which are based on the Block Outputs of the Block End COP that generated the program geometry.

Output Label

The name of the program output that comes out of the respective port. This is matched against the Output Name values on the Block End COP that generated the program geometry.

Output Type

The data type of the output and the corresponding port on this node.

Inputs

program_geometry

The geometry representation of a compiled program. Use the Block to Geometry COP to generate program geometry from a block.

input#

The source layer on which to run the program. The amount of node inputs and their details are based on the Inputs information.

Outputs

output#

The output layer with the program applied. The amount of node outputs and their details are based on the Outputs information.
