Unigine::PhysicalNoise Class

Header:#include <UniginePhysicals.h>
Inherits:Physical

A PhysicalNoise class is used to simulate a force field affecting physical bodies based on a volumetric noise texture. It creates an additional distribution flow specifying the force and the displacement direction for bodies at each point of the force field.

PhysicalNoise Class

Members


static PhysicalNoisePtr create(const Math::vec3 & size)

Constructor. Creates a physical noise node of the specified size.

Arguments
