Particle Operator (POP) Sample Code

This directory contains sample code for generating custom POPs. Refer to the toolkit documentation for more details.

RadialBirth POP

The radial birth POP will birth particles radially from a single point with a certain minimum and maximum distance from the point. This is an example of a generator POP.

SpotLight POP

The spotlight POP will change the particle's color to be brighter the closer it is to the point in 3D space. This is an example of a modifier POP that changes a particle's attributes.

LocalForce POP

The localforce POP applies a directional force that is localized. It has an origin, direction and an applied radius which define a tube in which the force is applied to the particles. This is an example of a POP that applies an acceleration to particles. The example also shows how to use guide geometry.

Install Script

sample_install.sh is a sample install script.

The script will first compile the sample source code, then install the icons so that Houdini will find them. By default, everything is installed in your home directory.
