Unigine::ObjectWaterGlobal Class
| Header: | #include <UnigineObjects.h> |
| Inherits: | Object |
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.

The FieldHeight physics mask.int getVisualFieldMask()
Returns the FieldHeight visual mask of the assigned material on the Global Water.Return value
The FieldHeight visual mask.int getWaterFieldHeightInteraction()
Checks if the assigned material on the Global Water object has enabled FieldHeight interaction option.Return value
1 if the FieldHeight interaction option is enabled, otherwise, 0.float getWaterLevel()
Returns the average 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.float getWaterLevelMin()
Returns the minimum Z coordinate of the water object.Return value
The Z coordinate value.float getWaterProceduralLevelMax(const Math::Vec3 & position)
Returns the maximum Z coordinate value of the water object including bounds of additional fields of other objects that affected Global Water heights in a given position.Arguments
- const Math::Vec3 & position - A position vector of additional fields.
float getWaterProceduralLevelMin(const Math::Vec3 & position)
Returns the minimum Z coordinate value of the water object including bounds of additional fields of other objects that affected Global Water heights in a given position.Arguments

void setWaterTime(float time)
Sets water time value for water synchronization.Arguments
- float time - Water time value.
float getWaterTime()
Returns water time value for water synchronization.Return value
Water time value.int getWorldIntersection(const Math::Vec3 & wp0, const Math::Vec3 & wp1, Math::vec3 * ret_point, Math::vec3 * ret_normal, Math::vec4 * ret_texcoord)
Searches for intersections with given line.Arguments
- const Math::Vec3 & wp0 - The line's start point coordinates.
- const Math::Vec3 & wp1 - The line's end point coordinates.
- Math::vec3 * ret_point - Intersection point coordinates.
- Math::vec3 * ret_normal - Normal vector of the intersection point.
- Math::vec4 * ret_texcoord - Texture coordinates of the intersection point (vec4, where vec4.xy is for the first (0) UV channel, vec4.zw is for the second (1) UV channel).
Return value
1 if intersections are found; otherwise, 0.int type()
