This class is used to create a global terrain object representing a certain fragment of Earth's surface on the basis of available GIS data (elevation and imagery). The global terrain is rendered using pre-generated tilesets which represent LODs for different data layers (heights, albedo, normals, and masks). Tilesets are managed via the TileSet class. Tileset data is stored in tileset files on the disk, these files are managed via the TileSetFile class

ObjectTerrainGlobal Class
Properties
bool IsForceIntersection#
A value indicating if forced loading of terrain tiles for intersection detection is enabled.
Notice
This option is used to enable force loading of terrain tiles to ensure correct intersection detection.
set
Enables or disables forced loading of necessary terrain tiles to ensure correct intersection detection.
set value -
1 to load necessary terrain tiles for intersection detection; otherwise, 0. The default value is 0.
Notice
When enabled, this option may significantly reduce performance. Thus, it is recommended to enable it, perform intersection check, and disable it again.
Texture HeightTextureArray#
The height textures array.
string HeightTextureArrayName#
The name of the height textures array.
set
Sets the name of the height textures array.
set value -
Name of the height textures array.
Texture NormalTextureArray#
The normal textures array.
string NormalTextureArrayName#
The name of the normal textures array.
set
Sets the name of the normal textures array.
set value -
Name of the normal textures array.
Texture AlbedoTextureArray#
The albedo textures array.
string AlbedoTextureArrayName#
The name of the albedo textures array.
set
Sets the name of the albedo textures array.
set value -
Name of the albedo textures array.
int NumDetails#
The total number of details.
int NumMasks#
The total number of masks.
