Houdini 22.0 Nodes Copernicus nodes

Point Generate Copernicus node

Adds points to a point cloud geometry.

On this page
Since 22.0

This node adds additional points to the provided geometry. The result will always be a point cloud - any incoming primitives will be lost.

If an id point attribute is present, the new points will gain successive ID values. Optional nextid and idstep detail attributes will be used for the starting ID value and distance between ID values.

Parameters

Method

How to compute the number of points to append.

Parameters

A specific number determined by parameters, as opposed to dynamically controlled by incoming attributes.

Point Attribute

Every point has an integer attribute for the number of times it should be replicated.

Detail Attribute

The geometry has an integer detail attribute for the number of points to create.

Number of Points

An exact number of points to create.

Points per Second

The number of points to create every second. When the node cooks, the current timestep is used to determine how much time should be considered to have elapsed. The resulting number of points may be fractional, in which case a random number is used to either keep or reject the fractional point.

Seed

The seed to determine if the fractional point is kept. This must vary over time or the generation will be biased.

Count Attribute

Name of the attribute to use for the count.

Copy Attributes

Attributes that match this pattern will be copied from the source point. Otherwise they are left at the default values.

Append Points

If appending, the new points are added to the end of the incoming geometry. Otherwise a new geometry is built with only the new points.

Inputs

points

A geometry input to either append points to or use as a reference for point attributes.

ref

An optional geometry input. If wired, this is used for the source of the count attribute and original point values.

count

An optional integer attribute input. If wired, this is used as the count attribute. In point mode must match the size of the source points.

Outputs

points

Output geometry with the newly generated points in it
