Unigine::PhysicalWater Class
| Header: | #include <UniginePhysicals.h> |
| Inherits: | Physical |
A PhysicalWater class is used to simulate water interaction effects.
Notice
The water will affect only objects, to which a cloth body or a rigid body are assigned.
If the rigid body is used, a shape should be also assigned.
