About
The VolumeGradient node in Houdini calculates the rate of change in a volume, providing a vector field that shows how values change across space. This is useful for simulating movement (like fluid or smoke), adding forces, and enhancing shading details by capturing directional changes in volume data. It’s essential for creating realistic simulations and effects.
