Unigine.ObjectLandscapeTerrain Class
| Inherits from: | Object |
This class is used to create and manage Landscape Terrain object and its detail masks.
ObjectLandscapeTerrain Class
Properties
float IntersectionPrecision#
The Precision for intersection detection as a fraction of maximum precision in the [0; 1] range. The default value is 0.5f. Maximum precision is determined by the Engine on the basis of the data of your Landscape Terrain.
int NumDetailMasks#
The total number of detail masks of the landscape terrain.
bool ActiveTerrain#
The value indicating if the landscape terrain is active.
long LastStreamingFrame#
The number of the frame when the last commit to the Virtual Texture was performed. This method enables you to check if the Landscape Terrain data is loaded completely at the moment (the Virtual Texture is created and the last commit to it is already applied).
Source code (C#)

ObjectLandscapeTerrain ( ) #
The ObjectLandscapeTerrain constructor.TerrainDetailMask GetDetailMask ( int num ) #
Returns the detail mask by its index. The number of detail masks is fixed and is equal to 20.Arguments
- int num - Detail mask index in the [0; 19] range.
Return value
Detail mask having the specified index.TerrainDetailMask GetDetailMaskSortRender ( int num ) #
Returns the detail mask by its rendering order. The number of detail masks is fixed and is equal to 20, masks rendering order is back to front.Arguments
- int num - Detail mask rendering order, in the [0; 19] range.
Return value
Detail mask having the specified rendering order.TerrainDetailMask FindChild ( string name ) #
Returns a child detail's number by its name. The search is performed among the immediate children only.Arguments
- string name - Detail mask name.
Return value
Detail mask having the specified name (if it exists); otherwise, nullptr.void GetDetailMasks ( TerrainDetailMask[] masks ) #
Builds the list of all detail masks of the landscape terrain and puts them to the specified buffer. The number of detail masks is fixed and is equal to 20.Arguments
- TerrainDetailMask[] masks - Buffer to which the list of detail masks it to be put.
void GetDetailMasksSortRender ( TerrainDetailMask[] masks ) #
Builds the list of all detail masks of the landscape terrain according to their rendering order (back to front) and puts them to the specified buffer. The number of detail masks is fixed and is equal to 20.Arguments
- TerrainDetailMask[] masks - Buffer to which the list of detail masks it to be put.
long GetLastStreamingFrame ( ) #
