Methods

• public constructor Create  ( AOwner :  TComponent ) ;
• public destructor Destroy  ( ) ;
• protected function GetHumanoid  ( )  : TGorillaTransform ;
• protected function GetLocalBindTransform  ( AIndex :  TControllerDef )  : TMatrix3D ;  inline;

• protected function GetJointRenderColor  ( )  : TAlphaColor ;
• protected procedure SetJointRenderColor  ( const  AValue :  TAlphaColor ) ;
• protected procedure DoRenderJoint  ( AContext :  TContext3D ) ;  virtual;
• protected procedure Render  ( ) ;  override;
• protected function GetIsSkeletonRoot  ( )  : Boolean ;
• protected procedure DoDuplicate  ( ASource :  TComponent; ADuplicator :  TGorillaDuplicator ) ;  override;

  Duplicates a TGorillaMesh/TGorillaModel and all of its submeshes. The method copies the complete memory structure and refreshes necessary lists and standalone components

• public function GetSkeletonTransformMatrix  ( )  : TMatrix3D ;

  Request the current transformation matrix to root node of skeleton. This is not the global offset, instead only to the skeleton root.

• public procedure SetLocalTransformMatrix  ( const  AMatrix :  TMatrix3D ) ;  override;
• public procedure SetLocalBindTransformMatrix  ( ACtrl :  TControllerDef; const  AMatrix :  TMatrix3D ) ;  virtual;
• public procedure CalculateInverseBindTransformMatrix  ( const  ACtrl :  TControllerDef; const  AParentBindTransform :  TMatrix3D ) ;
• public procedure AddJoint  ( const  AJoint :  TGorillaHAnimJoint ) ;

  NOTE: To support bind shape matrices we need this dirty hack if bind shape matrix is not identity, it means we have a bind shape transformation and we need to use binding transform instead of the given inverse bind matrix

• public function FindJoint  ( const  ADef :  TJointDef )  : TGorillaHAnimJoint ;
• public procedure ClearJoints  ( ) ;
• public procedure LoadFromDefinition  ( const  ADef :  TJointDef ) ;  overload virtual;
• public procedure PrepareSkinAnimation  ( ) ;

  Prepares every joint once for animation

• public procedure PrepareSkinAnimationStep  ( ACtrl :  TControllerDef ) ;

  Preparation of every joint at any animation frame based on the submitted skeleton transformation matrix.

• public procedure ApplyJointInfoToHumanoid  ( const  ACtrl :  TControllerDef; const  AVertices :  TVertexJointsList; AMeshDef :  TMeshDef  =  nil ) ;

  Setting up the TVertexJointsList, which contains information which joint affects which vertices. at first all shape vertices were added to that TVertexJointsList. and afterwards we iterate through all joints and check what vertices they affect

• public procedure DebugOut  ( const  ATab :  string ) ;

Properties

• public Humanoid : TGorillaTransform

  Parent humanoid component

  read GetHumanoid
  
• public Joints : TObjectList<Gorilla.HAnim.Joint.TGorillaHAnimJoint>

  List of all joints inside the skeleton, except the skeleton joint itself.

  read FJoints
  
• public Skinned : Boolean

  Is joint used for skin-animation or skeleton-animation

  read FSkinned
  
• public IsSkeletonRoot : Boolean

  Is this joint the origin of all other joints

  read GetIsSkeletonRoot
  
• public ShowJoint : Boolean

  Should joints be displayed while rendering. Helpful for debugging problems with animations. Or for editing humanoid skeleton.

  read GetShowJoint
  write SetShowJoint
  
• public JointRenderColor : TAlphaColor

  If ShowJoint is set to true the component renders its joint visually. This property defines the color used for rendering a cube.

  read GetJointRenderColor
  write SetJointRenderColor
  
• public JointRenderSize : TPoint3D

  Define the joint render cube size. By default it's (0.25, 0.25, 0.25)

  read FJointRenderSize
  write FJointRenderSize
  
• public LocalBindTransform[Index] : TMatrix3D

  For reading local bind transform matrix

  read GetLocalBindTransform
  
• public CurrentOffsetMatrix[Index] : TMatrix3D

  At animation-time generated matrix which represents the offset between the current transformation and binding transformation

  read GetCurrentOffsetMatrix
