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.

function ProjectionMatrix: TMatrix4; override; |
|
This item has no description. Showing description inherited from TAbstractViewpointNode.ProjectionMatrix.
Matrices for projecting texture from this viewpoint, for ProjectedTextureCoordinate. Override Source: src/scene/x3d/x3dnodes_standard_navigation.inc (line 247). | |
|
procedure CreateNode; override; |
|
Create node fields and events. Source: src/scene/x3d/auto_generated_node_helpers/x3dnodes_viewpoint.inc (line 33). | |
|
class function ClassX3DType: String; override; |
|
This item has no description. Showing description inherited from TX3DNode.ClassX3DType. Node type name in VRML/X3D, for this class. Normal VRML/X3D node classes should override this to return something non-empty, and then X3DType automatically will return the same value. Empty for classes that don't have a hardcoded VRML/X3D node name, like a special TX3DUnknownNode. Such special classes should override then X3DType to return actual non-empty name there. You usually should call X3DType. The only use of this method is that it works on classes (it's "class function"), without needing at actual instance.
