|
|
|
|
The FOV of the camera. This class and glTF define the camera FOV in radians, while Godot uses degrees. This maps to glTF's ``yfov`` property. This value is only used for perspective cameras, when :ref:`perspective<class_GLTFCamera_property_perspective>` is ``true``.

If ``true``, the camera is in perspective mode. Otherwise, the camera is in orthographic/orthogonal mode. This maps to glTF's camera ``type`` property. See :ref:`Camera3D.projection<class_Camera3D_property_projection>` and the glTF spec for more information.

|
The size of the camera. This class and glTF define the camera size magnitude as a radius in meters, while Godot defines it as a diameter in meters. This maps to glTF's ``ymag`` property. This value is only used for orthographic/orthogonal cameras, when :ref:`perspective<class_GLTFCamera_property_perspective>` is ``false``.
