Gorilla.Terrain.Utils

Methods

• protected procedure RebuildPlane  ( const  AMeshData :  TMeshData; const  ASubDivWidth :  Integer; const  ASubDivHeight :  Integer; const  ATwoFace :  Boolean ) ;  class;

  Rebuilds the internal raw grid plane. This method ignores any heightmap manipulations and only returns a plane with the given rows and columns.

• protected procedure RebuildSphere  ( const  AMeshData :  TMeshData; const  ASubDivAxes :  Integer; const  ASubDivHeight :  Integer; const  ATwoFace :  Boolean ) ;  class;
• public procedure BuildTerrainFromHeightMap  ( const  AMeshData :  TMeshData; const  ASubDivWidth :  Integer; const  ASubDivHeight :  Integer; const  ATwoFace :  Boolean; const  AHeightMap :  TBitmap; const  AHeightScale :  Single; const  ASmoothing :  Integer ) ;  class;

  Clears the previous terrain and rebuilds it from given heightmap. Procedural algorithms will also use this method, after building their heightmap.

  Parameters

  • const  AMeshData :  TMeshData  -  The vertex/index buffer where to write generated vertices to. Subdivisions in X direction. Subdivisions in Z direction. Should vertices be created on both sides of the grid. A heightmap bitmap to generate a terrain from. A scaling value for Y-position of each vertex. A smoothing value. The higher the value the more the terrain getting smoothed. A zero value means no smoothing.
  • const  ASubDivWidth :  Integer  -  The vertex/index buffer where to write generated vertices to. Subdivisions in X direction. Subdivisions in Z direction. Should vertices be created on both sides of the grid. A heightmap bitmap to generate a terrain from. A scaling value for Y-position of each vertex. A smoothing value. The higher the value the more the terrain getting smoothed. A zero value means no smoothing.
