Gorilla.Billboard

Fields

• protected FBillboard : TGorillaBillboard
  
• protected FCount : Integer
  
• protected FOnCreateProxy : TOnBillboardProxyCreate
  

Methods

• public constructor Create  ( const  ABillboard :  TGorillaBillboard ) ;
• public destructor Destroy  ( ) ;
• public procedure Execute  ( ) ;  abstract virtual;

  On extending the filling algorithm class you need to overwrite this routine.

Properties

• public Billboard : TGorillaBillboard

  Get the owner billboard component.

  read FBillboard
  
• public Count : Integer

  Get or set the number of billboard proxies to create.

  read FCount
  write FCount
  

Methods

• public constructor Create  ( const  ABillboard :  TGorillaBillboard ) ;
• public procedure Execute  ( ) ;  override;

Fields

• protected FRandomPosition : Boolean
  

Methods

• public constructor Create  ( const  ABillboard :  TGorillaBillboard; const  ATerrain :  TGorillaMesh ) ;
• public procedure Execute  ( ) ;  override;

Properties

• public RandomPosition : Boolean

  By this property you can switch between column-row filling and random position generation.

Methods

• public constructor Create  ( AOwner :  TComponent ) ;
• public destructor Destroy  ( ) ;
• protected procedure DoOnSourceObjectNotify  ( ASender :  TObject; const  AItem :  TGorillaBillboardSourceObject; AAction :  TCollectionNotification ) ;
• protected function DoGetSourceObjectsList  ( )  : TGorillaBillboardSourceObjectList ;
• protected procedure DoSetOutputBuffer  ( ASrcList :  TGorillaBillboardSourceObjectList; AVB :  TVertexBuffer; AIB :  TIndexBuffer ) ;

• public function GetAbsoluteBoundingBox  ( )  : TBoundingBox ;  override;
• public procedure Fill  ( const  AAlgorithm :  TGorillaBillboardFillingAlgorithm; const  ADoClear :  Boolean ) ;  virtual;

  Create a number of proxies by an individual algorithm.

• public procedure Merge  ( ) ;  virtual;
• public function AddSourceObject  ( const  ACtrl :  TControl3D; const  AUnique :  Boolean  =  False )  : Integer ;

  Add a new source object to list of source objects. If AUnique is TRUE the method will take care that only single instances of this control are contained.

• public procedure RemoveSourceObject  ( const  ACtrl :  TControl3D; const  AAllCopies :  Boolean  =  False ) ;

  Remove source object from list.

• public procedure DeleteSourceObject  ( const  AIndex :  Integer ) ;

  Delete a source object at a certain position in source object list.

• public function GetSourceObject  ( const  AIndex :  Integer )  : TControl3D ;

  Returns a source object at a certain position in source object list.

• public function CountSourceObjects  ( )  : Integer ;

  Counts added source objects.

• public procedure ClearSourceObjects  ( ) ;

  Deletes all source objects from source object list.

Properties

• public SourceObjects : TList<FMX.Controls3D.TControl3D>

  Returns a list of TControl3D components to be multiplied in billboard. Add controls at runtime and setup a list before starting filling mechanism.

  read FSourceObjects
  
• public Billboards : TList<Gorilla.Billboard.TGorillaBillboardProxy>

  Stored position, rotation and scaling of all source object instances.
