Description

Methods

Public class function ProjectionType: TProjectionType; override;
 
Public class function InternalFieldOfView(FieldOfView: Single; const FieldOfViewAxis: TFieldOfViewAxis; const ViewportWidth, ViewportHeight: Single): TVector2;

Calculate both perspective angles (in radians), knowing TCastleCamera.Perspective.FieldOfView and TCastleCamera.Perspective.FieldOfViewAxis.

In particular when FieldOfViewAxis = faSmallest then we perform the calculation requested by X3D specification about ViewpointNode fieldOfView behavior.

Public function ProjectionMatrix: TMatrix4; override;
 
Public procedure CreateNode; override;

Create node fields and events.

Public class function ClassX3DType: String; override;
 

Properties

Public property FdFieldOfView: TSFFloat read FFdFieldOfView;

Internal wrapper for property FieldOfView. This wrapper API may change, we advise to access simpler FieldOfView instead, if it is defined (TODO: for now, some field types do not have a simpler counterpart).

Public property FieldOfView: Single read GetFieldOfView write SetFieldOfView;
 
Public property FdPosition: TSFVec3f read FFdPosition;

Internal wrapper for property Position. This wrapper API may change, we advise to access simpler Position instead, if it is defined (TODO: for now, some field types do not have a simpler counterpart).

Public property FdFieldOfViewForceVertical: TSFBool read FFdFieldOfViewForceVertical;

Internal wrapper for property FieldOfViewForceVertical. This wrapper API may change, we advise to access simpler FieldOfViewForceVertical instead, if it is defined (TODO: for now, some field types do not have a simpler counterpart).

Public property FieldOfViewForceVertical: Boolean read GetFieldOfViewForceVertical write SetFieldOfViewForceVertical;
