Unigine::PhysicalNoise Class

Interface for physical noise handling. The physical noise is based on the volumetric noise texture. It is used to simulate a force field affecting particles and objects with spatial 3D noise. The physical noise can be applied either to Particle objects or Physics bodies.

To use this class, include the UniginePhysicalNoise.h file.
