Unigine::ObjectTerrainGlobal Class

Header: #include <UnigineObjects.h>
Inherits from: Object

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

Members


static ObjectTerrainGlobalPtr create ( ) #

Constructor. Creates a new empty global terrain object with default properties.

void clear ( ) #

Clears all terrain data (lods, textures, details, masks etc.).

static int type ( ) #

Returns the type of the object.

Return value

ObjectTerrainGlobal type identifier.

Ptr<TerrainGlobalLods> getAlbedoLods ( ) #

Returns the group of terrain albedo LODs.

Return value

Terrain albedo LODs group.

Ptr<Texture> getAlbedoTextureArray ( ) const#

Returns the albedo textures array.

Return value

Albedo textures array.

void setAlbedoTextureArrayName ( const char * name ) #

Sets the name of the albedo textures array.

Arguments

  • const char * name - Name of the albedo textures array.

const char * getAlbedoTextureArrayName ( ) const#

Returns the name of the albedo textures array.

Return value

Name of the albedo textures array.

int addDetail ( const char * name ) #

Adds a new detail to the vector of terrain details.

Arguments

  • const char * name - Detail name.

Return value

Number of the new detail.

int cloneDetail ( int num ) #

Clones the detail with the specified number.

Arguments

  • int num - Detail number.

Return value

Number of the new cloned terrain detail.

Ptr<TerrainGlobalDetail> getDetail ( int num ) #

Returns the terrain detail with the specified number.

Arguments

  • int num - Detail number.

Return value

Terrain detail.

void removeDetail ( int num ) #

Removes the detail with the specified number.

Arguments

  • int num - Detail number.

void swapDetail ( int num_0, int num_1 ) #

Swaps two details of the terrain.

Arguments

  • int num_0 - Number of the first detail.
  • int num_1 - Number of the second detail.

void resizeDetails ( int size ) #

Resizes the vector of terrain details.

Arguments

  • int size - New size.

int getNumDetails ( ) const#

Returns the total number of details.

Return value

Number of details.

void setForceIntersection ( bool intersection ) #

Enables or disables forced loading of necessary terrain tiles to ensure correct intersection detection.

Notice
  • When enabled, this option may significantly reduce performance. Thus, it is recommended to enable it, perform intersection check, and disable it again.
  • It is recommended to make two or more intersection requests to make sure you get the required result when necessary, as in some rare cases forced loading of tiles may not give you a 100% guarantee.

Arguments

  • bool intersection - true to load necessary terrain tiles for intersection detection; otherwise, false. The default value is false.

bool isForceIntersection ( ) const#

Returns 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.

Return value

false if forced loading of terrain tiles for intersection detection is enabled; otherwise, false.

int addMask ( const char * name ) #

Adds a new mask to the vector of masks.

Arguments

  • const char * name - Mask name.

Return value

Number of the new mask, if the mask was added successfully; otherwise, -1.

int cloneMask ( int num ) #

Clones the mask with the specified number.

Arguments

  • int num - Mask number.

Return value

Number of the new cloned mask.

void removeMask ( int num ) #

Removes the mask with the specified number from the vector of masks.

Arguments

  • int num - Mask number.

void swapMask ( int num_0, int num_1 ) #

Swaps two masks.

Arguments

  • int num_0 - Number of the first mask.
  • int num_1 - Number of the second mask.

void replaceMasks ( const Vector< String > & names ) #

Replaces the list of masks with a given one.
Notice
If a mask used by some detail is missing in the new list, such detail will be considered as having no mask assigned, otherwise it will keep its mask.

Arguments

void resizeMasks ( int size ) #

Resizes the vector of masks.

Arguments

  • int size - New size.

int getNumMasks ( ) const#

Returns the total number of masks.

Return value

Number of masks.
