Viewport
========

**Inherits:** :ref:`Node<class_Node>` **<** :ref:`Object<class_Object>`

Creates a sub-view into the screen.

.. rst-class:: classref-introduction-group

Description
-----------

A Viewport creates a different view into the screen, or a sub-view inside another viewport. Children 2D Nodes will display on it, and children Camera 3D nodes will render on it too.

Optionally, a viewport can have its own 2D or 3D world, so they don't share what they draw with other viewports.

If a viewport is a child of a :ref:`ViewportContainer<class_ViewportContainer>`, the viewport will automatically take up the container's size, otherwise it must be set manually.

Viewports can also choose to be audio listeners, so they generate positional audio depending on a 2D or 3D camera child of it.

Also, viewports can be assigned to different screens in case the devices have multiple screens.

Finally, viewports can also behave as render targets, in which case they will not be visible unless the associated texture is used to draw.

\ **Note:** By default, a newly created Viewport in Godot 3.x will appear to be upside down. Enabling :ref:`render_target_v_flip<class_Viewport_property_render_target_v_flip>` will display the Viewport with the correct orientation.

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

- void **set_use_debanding** **(** :ref:`bool<class_bool>` value **)**
- :ref:`bool<class_bool>` **get_use_debanding** **(** **)**

If ``true``, uses a fast post-processing filter to make banding significantly less visible in 3D. 2D rendering is *not* affected by debanding unless the :ref:`Environment.background_mode<class_Environment_property_background_mode>` is :ref:`Environment.BG_CANVAS<class_Environment_constant_BG_CANVAS>`. In this case, :ref:`usage<class_Viewport_property_usage>` must also be set to :ref:`USAGE_3D<class_Viewport_constant_USAGE_3D>`. See also :ref:`ProjectSettings.rendering/quality/filters/use_debanding<class_ProjectSettings_property_rendering/quality/filters/use_debanding>`.

In some cases, debanding may introduce a slightly noticeable dithering pattern. It's recommended to enable debanding only when actually needed since the dithering pattern will make lossless-compressed screenshots larger.

\ **Note:** Only available on the GLES3 backend. :ref:`hdr<class_Viewport_property_hdr>` must also be ``true`` for debanding to be effective.

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

- void **set_use_fxaa** **(** :ref:`bool<class_bool>` value **)**
- :ref:`bool<class_bool>` **get_use_fxaa** **(** **)**

Enables fast approximate antialiasing. FXAA is a popular screen-space antialiasing method, which is fast but will make the image look blurry, especially at lower resolutions. It can still work relatively well at large resolutions such as 1440p and 4K. Some of the lost sharpness can be recovered by enabling contrast-adaptive sharpening (see :ref:`sharpen_intensity<class_Viewport_property_sharpen_intensity>`).

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

- void **set_hdr** **(** :ref:`bool<class_bool>` value **)**
- :ref:`bool<class_bool>` **get_hdr** **(** **)**

If ``true``, the viewport rendering will receive benefits from High Dynamic Range algorithm. High Dynamic Range allows the viewport to receive values that are outside the 0-1 range. In Godot, HDR uses half floating-point precision (16-bit) by default. To use full floating-point precision (32-bit), enable :ref:`use_32_bpc_depth<class_Viewport_property_use_32_bpc_depth>`.

\ **Note:** Requires :ref:`usage<class_Viewport_property_usage>` to be set to :ref:`USAGE_3D<class_Viewport_constant_USAGE_3D>` or :ref:`USAGE_3D_NO_EFFECTS<class_Viewport_constant_USAGE_3D_NO_EFFECTS>`, since HDR is not supported for 2D.

- void **set_keep_3d_linear** **(** :ref:`bool<class_bool>` value **)**
- :ref:`bool<class_bool>` **get_keep_3d_linear** **(** **)**

If ``true``, the result after 3D rendering will not have a linear to sRGB color conversion applied. This is important when the viewport is used as a render target where the result is used as a texture on a 3D object rendered in another viewport. It is also important if the viewport is used to create data that is not color based (noise, heightmaps, pickmaps, etc.). Do not enable this when the viewport is used as a texture on a 2D object or if the viewport is your final output. For the GLES2 driver this will convert the sRGB output to linear, this should only be used for VR plugins that require input in linear color space!

- void **set_use_render_direct_to_screen** **(** :ref:`bool<class_bool>` value **)**
- :ref:`bool<class_bool>` **is_using_render_direct_to_screen** **(** **)**

If ``true``, renders the Viewport directly to the screen instead of to the root viewport. Only available in GLES2. This is a low-level optimization and should not be used in most cases. If used, reading from the Viewport or from ``SCREEN_TEXTURE`` becomes unavailable.

The shadow atlas' resolution (used for omni and spot lights). The value will be rounded up to the nearest power of 2.

\ **Note:** If this is set to ``0``, both point *and* directional shadows won't be visible. Since user-created viewports default to a value of ``0``, this value must be set above ``0`` manually (typically at least ``256``).

If set to a value greater than ``0.0``, contrast-adaptive sharpening will be applied to the 3D viewport.

- :ref:`Usage<enum_Viewport_Usage>` **get_usage** **(** **)**

The viewport's rendering mode. This controls which buffers are allocated for the viewport (2D only, or 2D + 3D). 2D-only options can reduce memory usage and improve performance slightly, especially on low-end devices.

\ **Note:** If set to :ref:`USAGE_2D<class_Viewport_constant_USAGE_2D>` or :ref:`USAGE_2D_NO_SAMPLING<class_Viewport_constant_USAGE_2D_NO_SAMPLING>`, :ref:`hdr<class_Viewport_property_hdr>` will have no effect when enabled since HDR is not supported for 2D.

If ``true``, allocates the viewport's framebuffer with full floating-point precision (32-bit) instead of half floating-point precision (16-bit). Only effective when :ref:`hdr<class_Viewport_property_hdr>` is also enabled.

\ **Note:** Enabling this setting does not improve rendering quality. Using full floating-point precision is slower, and is generally only needed for advanced shaders that require a high level of precision. To reduce banding, enable :ref:`debanding<class_Viewport_property_debanding>` instead.

.. rst-class:: classref-method

:ref:`bool<class_bool>` **is_size_override_enabled** **(** **)** |const|

Returns ``true`` if the size override is enabled. See :ref:`set_size_override<class_Viewport_method_set_size_override>`.

.. _class_Viewport_method_set_attach_to_screen_rect:

.. rst-class:: classref-method

void **set_attach_to_screen_rect** **(** :ref:`Rect2<class_Rect2>` rect **)**

Attaches this **Viewport** to the root **Viewport** with the specified rectangle. This bypasses the need for another node to display this **Viewport** but makes you responsible for updating the position of this **Viewport** manually.

.. _class_Viewport_method_set_input_as_handled:

.. rst-class:: classref-method

void **set_input_as_handled** **(** **)**

Stops the input from propagating further down the :ref:`SceneTree<class_SceneTree>`.

.. rst-class:: classref-method

void **set_shadow_atlas_quadrant_subdiv** **(** :ref:`int<class_int>` quadrant, :ref:`ShadowAtlasQuadrantSubdiv<enum_Viewport_ShadowAtlasQuadrantSubdiv>` subdiv **)**

Sets the number of subdivisions to use in the specified quadrant. A higher number of subdivisions allows you to have more shadows in the scene at once, but reduces the quality of the shadows. A good practice is to have quadrants with a varying number of subdivisions and to have as few subdivisions as possible.

.. _class_Viewport_method_set_size_override:

.. rst-class:: classref-method

void **set_size_override** **(** :ref:`bool<class_bool>` enable, :ref:`Vector2<class_Vector2>` size=Vector2( -1, -1 ), :ref:`Vector2<class_Vector2>` margin=Vector2( 0, 0 ) **)**

Sets the size override of the viewport. If the ``enable`` parameter is ``true`` the override is used, otherwise it uses the default size. If the size parameter is ``(-1, -1)``, it won't update the size.

void **warp_mouse** **(** :ref:`Vector2<class_Vector2>` to_position **)**

Moves the mouse pointer to the specified position in this **Viewport** using the coordinate system of this **Viewport**.
