Gorilla.DefTypes.Cache

Methods

• public function GetSourceStream  ( const  AFormat :  TVertexFormat; const  ABuffer :  TVertexBuffer )  : TMemoryStream ;  class overload;

  Extracts a part of the supplied vertex buffer to a memory stream.

• public function GetSourceStream  ( const  AData :  Pointer; const  ASize :  Int64 )  : TMemoryStream ;  class overload;

  Creates a new memory stream and copies the data from the supplied buffer pointer into the stream.

• public procedure SetSourceStream  ( const  AFormat :  TVertexFormat; const  ABuffer :  TVertexBuffer; const  AStream :  TMemoryStream ) ;  class overload;

  Copies a part of the vertex buffer depending on the supplied vertex-format into an existing memory stream.

• public procedure SetSourceStream  ( const  AData :  Pointer; const  ASize :  Int64; const  AStream :  TMemoryStream ) ;  class overload;

  Copies the data from the supplied buffer pointer into an existing memory stream.

• public function Compress  ( const  AFormat :  TVertexFormat; const  ABuffer :  TVertexBuffer )  : TMemoryStream ;  class overload;

  Returns a new memory stream with the compressed data, requested by GetSourceStream() depending on the supplied vertex buffer and format.

• public function Compress  ( const  AData :  Pointer; const  ASize :  Int64 )  : TMemoryStream ;  class overload;

  Returns a new memory stream with the compressed data, supplied by a buffer pointer and size.

• public function Decompress  ( const  AStream :  TMemoryStream )  : TMemoryStream ;  class;

  Decompresses the supplied memory stream and returns a new memory stream.

Methods

• public constructor Create  ( const  ADef :  TModelDef; const  AFlags :  TAnimationCachingFlags  =  [] ; const  AModel :  TComponent  =  nil ) ;
• public destructor Destroy  ( ) ;
• protected procedure DoOnMeshBufferNotify  ( ASender :  TObject; const  AItem :  TVertexBuffer; AAction :  TCollectionNotification ) ;
• protected procedure DoPrepare  ( const  AAnim :  TObject ) ;

  This method checks if only a part of the vertex buffer is cached. If so, it creates a new vertex-buffer which easily can be copied, instead of extracting each element.

• protected procedure DoCleanup  ( const  AAnim :  TObject ) ;

  Destroys eventually created helper structures from DoPrepare().

• protected procedure Setup  ( ) ;

  If FModel is not assigned yet, the routine will create a temporary TGorillaModel and apply the model definition to it for caching process.

• public procedure BeginFrame  ( const  ACurrent :  Integer; const  ATotal :  Integer ) ;

  Executed at the beginning of each frame-caching and for each mesh of the model.

• public procedure EndFrame  ( const  ACurrent :  Integer; const  ATotal :  Integer ) ;

  Executed at the end of each frame-caching and for each meah of the model.

• public procedure Execute  ( const  AAnimDef :  TAnimationDef ) ;

  Starts caching process for a specific model. The routine will generate bufferobject for each frame of the animation and for all meshes inside of this model.

Properties

• public Flags : TAnimationCachingFlags

  Caching configuration flags.
