ObjectWaterGlobal Class

Interface for object water global handling. A water object represents infinitely spread water (global water) with auto-tessellation (wireframe of the water object is not scaled - regardless of the camera position it stays the same) and the underwater mode. This type is suitable to represent boundless ocean while not overloading the GPU.

However, it cannot have a body assigned, and thus does not provide proper physical interaction with scene objects. Also it is limited to a single water level. It means that the filling level of water always remains the same. So, if you need to create, for example, mountain lakes or water flows with height difference, you should use a water mesh.

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

ObjectWaterGlobal ()

Constructor. Creates a new global water object.

float getWaterLevel ()

Returns the minimum Z coordinate of the water object.

Return value

The Z coordinate value.

float getWaterLevelMax ()

Returns the maximum Z coordinate of the water object.

Return value

The Z coordinate value.

Math::vec3 getNormal (const Math::Vec3 & position)

Returns a normal vector of a given point (to orient objects along the waves normals).

Arguments

• const Math::Vec3 & position - Normal vector.

Return value

Normal vector.

float getHeight (const Math::Vec3 & position)

Returns a height offset of a given point relatively to the water surface.

Arguments

• const Math::Vec3 & position - Point position coordinates.

Return value

Height offset of the point.
