Methods

• public constructor Create  ( ASystem :  IGorillaFMODSystem; const  AMaxPolygons :  Integer; const  AMaxVertices :  Integer ) ;

• public constructor CreateFromData  ( ASystem :  IGorillaFMODSystem; const  AData :  Pointer; const  ADatasize :  Integer ) ;

  Creates a geometry object from a block of memory which contains pre-saved geometry data, saved by Geometry::save.

• public destructor Destroy  ( ) ;

  Frees a geometry object and releases its memory.

• public procedure AddPolygon  ( const  APolygon :  TGorillaFMODPolygon ) ;

  Adds a polygon to an existing geometry object.

• public function GetPolygonNumVertices  ( AIndex :  Integer )  : Integer ;

  Gets the number of vertices in a polygon which is part of the geometry object.

  Parameters

  • AIndex :  Integer  -  Polygon index. This must be in the range of 0 to Geometry::getNumPolygons minus 1.
• public procedure SetPolygonVertex  ( AIndex :  Integer; AVertexIndex :  Integer; const  AVertex :  TPoint3D ) ;

  Alters the position of a polygon's vertex inside a geometry object.

  Parameters

  • AIndex :  Integer  -  Polygon index. This must be in the range of 0 to Geometry::getNumPolygons minus 1. Vertex index inside the polygon. This must be in the range of 0 to Geometry::getPolygonNumVertices minus 1. Address of an FMOD_VECTOR which holds the new vertex location.
  • AVertexIndex :  Integer  -  Polygon index. This must be in the range of 0 to Geometry::getNumPolygons minus 1. Vertex index inside the polygon. This must be in the range of 0 to Geometry::getPolygonNumVertices minus 1. Address of an FMOD_VECTOR which holds the new vertex location.
  • const  AVertex :  TPoint3D  -  Polygon index. This must be in the range of 0 to Geometry::getNumPolygons minus 1. Vertex index inside the polygon. This must be in the range of 0 to Geometry::getPolygonNumVertices minus 1. Address of an FMOD_VECTOR which holds the new vertex location.
• public function GetPolygonVertex  ( AIndex :  Integer; AVertexIndex :  Integer )  : TPoint3D ;

  Retrieves the position of the vertex inside a geometry object.

  Parameters

  • AIndex :  Integer  -  Polygon index. This must be in the range of 0 to Geometry::getNumPolygons minus 1. Vertex index inside the polygon. This must be in the range of 0 to Geometry::getPolygonNumVertices minus 1.
  • AVertexIndex :  Integer  -  Polygon index. This must be in the range of 0 to Geometry::getNumPolygons minus 1. Vertex index inside the polygon. This must be in the range of 0 to Geometry::getPolygonNumVertices minus 1.
• public procedure Save  ( AData :  Pointer; ADataSize :  PFMOD_Int ) ;

  Saves the geometry object as a serialized binary block, to a user memory buffer. This can then be saved to a file if required and loaded later with System::loadGeometry.

  Parameters

  • AData :  Pointer  -  Address of a variable to receive the serialized geometry object. Specify 0 or NULL to have the datasize parameter return the size of the memory required for this saved object. Address of a variable to receive the size in bytes required to save this object when 'data' parameter is 0 or NULL.
  • ADataSize :  PFMOD_Int  -  Address of a variable to receive the serialized geometry object. Specify 0 or NULL to have the datasize parameter return the size of the memory required for this saved object. Address of a variable to receive the size in bytes required to save this object when 'data' parameter is 0 or NULL.

Properties

• public UserData : Pointer

  A user value that the Geometry object will store internally. Can be retrieved with Geometry::getUserData.

  read GetUserData
  write SetUserData
  
• public Active : LongBool

  Enables or disables an object from being processed in the geometry engine.

  read GetActive
  write SetActive
  
• public Rotation : TGorillaFMODOrientation

  The orientation of the geometry object.

  read GetRotation
  write SetRotation
  
• public Position : TPoint3D

  Sets the position of the object in world space, which is the same space FMOD sounds and listeners reside in.

  read GetPosition
  write SetPosition
  
• public Scale : TPoint3D

  Sets the relative scale vector of the geometry object. An object can be scaled/warped in all 3 dimensions separately using the vector without having to modify polygon data.

  read GetScale
  write SetScale
  
• public NumPolygons : Integer

  Retrieves the number of polygons stored within this geometry object.

  read GetNumPolygons
  
• public MaxPolygons : TGorillaFMODMaxPolygons

  Retrieves the maximum number of polygons and vertices allocatable for this object. This is not the number of polygons or vertices currently present. The maximum number was set with System::createGeometry.

  read GetMaxPolygons
  
• public PolygonAttributes[Index] : TGorillaFMODPolygonAttributes

  Individual attributes for each polygon inside a geometry object.

  read GetPolygonAttributes
  write SetPolygonAttributes
