class function InternalFieldOfView( const AFieldOfView: TFloatRectangle; const ViewportWidth, ViewportHeight: Single): TFloatRectangle; |
|
Calculate final field of view value, taking into account aspect ratio. The idea is that OrthoViewpoint.fieldOfView specifies the minimal extents. Depending on your window aspect ratio, you may need to make one extent (vertical or horizontal) larger to adjust. Source: src/scene/x3d/x3dnodes_standard_navigation.inc (line 221). | |

procedure CreateNode; override; |
|
Create node fields and events. Source: src/scene/x3d/auto_generated_node_helpers/x3dnodes_orthoviewpoint.inc (line 28). | |
|
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.

Field of view determines how much you see in the camera. Use this e.g. to zoom in/out. This property has comfortable getter and setter, you can also get and set the indexes in 0..3 range, where
