Example for

Volume Sample


This example demonstrates how to set attributes on a particle based on the value of a volume at the particle’s position.

To accomplish this, you can use a VOP POP to edit the particles, using the Volume Sample from File VOP to sample the volume.

In the example, particles are colored differently based on whether they are "in" or "out" of the volume, where "in" is defined in the example as "the value in the volume is > 0 at the position of the particle", but could easily be changed.
