Property Descriptions
---------------------

.. _class_GLTFCamera_property_depth_far:

.. rst-class:: classref-property

:ref:`float<class_float>` **depth_far** = ``4000.0``

.. rst-class:: classref-property-setget

- void **set_depth_far** **(** :ref:`float<class_float>` value **)**
- :ref:`float<class_float>` **get_depth_far** **(** **)**

The distance to the far culling boundary for this camera relative to its local Z axis, in meters. This maps to GLTF's ``zfar`` property.

.. rst-class:: classref-item-separator

----

.. _class_GLTFCamera_property_depth_near:

.. rst-class:: classref-property

:ref:`float<class_float>` **depth_near** = ``0.05``

.. rst-class:: classref-property-setget

- void **set_depth_near** **(** :ref:`float<class_float>` value **)**
- :ref:`float<class_float>` **get_depth_near** **(** **)**

The distance to the near culling boundary for this camera relative to its local Z axis, in meters. This maps to GLTF's ``znear`` property.

.. rst-class:: classref-item-separator

----

.. _class_GLTFCamera_property_fov:

.. rst-class:: classref-property

:ref:`float<class_float>` **fov** = ``1.309``

.. rst-class:: classref-property-setget

- void **set_fov** **(** :ref:`float<class_float>` value **)**
- :ref:`float<class_float>` **get_fov** **(** **)**

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.

.. rst-class:: classref-item-separator

----

.. _class_GLTFCamera_property_perspective:

.. rst-class:: classref-property

:ref:`bool<class_bool>` **perspective** = ``true``

.. rst-class:: classref-property-setget

- void **set_perspective** **(** :ref:`bool<class_bool>` value **)**
- :ref:`bool<class_bool>` **get_perspective** **(** **)**

Whether or not the camera is in perspective mode. If false, 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.

.. rst-class:: classref-item-separator

----

.. _class_GLTFCamera_property_size_mag:

.. rst-class:: classref-property

:ref:`float<class_float>` **size_mag** = ``0.5``

.. rst-class:: classref-property-setget

- void **set_size_mag** **(** :ref:`float<class_float>` value **)**
- :ref:`float<class_float>` **get_size_mag** **(** **)**

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.

Method Descriptions
-------------------

.. _class_GLTFCamera_method_from_dictionary:

.. rst-class:: classref-method

:ref:`GLTFCamera<class_GLTFCamera>` **from_dictionary** **(** :ref:`Dictionary<class_Dictionary>` dictionary **)** |static|

Creates a new GLTFCamera instance by parsing the given :ref:`Dictionary<class_Dictionary>`.

.. rst-class:: classref-item-separator

----

.. _class_GLTFCamera_method_from_node:

.. rst-class:: classref-method

:ref:`GLTFCamera<class_GLTFCamera>` **from_node** **(** :ref:`Camera3D<class_Camera3D>` camera_node **)** |static|

Create a new GLTFCamera instance from the given Godot :ref:`Camera3D<class_Camera3D>` node.

.. rst-class:: classref-item-separator

----

.. _class_GLTFCamera_method_to_dictionary:

.. rst-class:: classref-method

:ref:`Dictionary<class_Dictionary>` **to_dictionary** **(** **)** |const|

Serializes this GLTFCamera instance into a :ref:`Dictionary<class_Dictionary>`.

.. rst-class:: classref-item-separator

----

.. _class_GLTFCamera_method_to_node:

.. rst-class:: classref-method

:ref:`Camera3D<class_Camera3D>` **to_node** **(** **)** |const|

Converts this GLTFCamera instance into a Godot :ref:`Camera3D<class_Camera3D>` node.

.. |virtual| replace:: :abbr:`virtual (This method should typically be overridden by the user to have any effect.)`
.. |const| replace:: :abbr:`const (This method has no side effects. It doesn't modify any of the instance's member variables.)`
.. |vararg| replace:: :abbr:`vararg (This method accepts any number of arguments after the ones described here.)`
.. |constructor| replace:: :abbr:`constructor (This method is used to construct a type.)`
.. |static| replace:: :abbr:`static (This method doesn't need an instance to be called, so it can be called directly using the class name.)`
.. |operator| replace:: :abbr:`operator (This method describes a valid operator to use with this type as left-hand operand.)`
.. |bitfield| replace:: :abbr:`BitField (This value is an integer composed as a bitmask of the following flags.)`
