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

**Inherited By:** :ref:`SubViewport<class_SubViewport>`, :ref:`Window<class_Window>`

Abstract base class for viewports. Encapsulates drawing and interaction with a game world.

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

A **Viewport** creates a different view into the screen, or a sub-view inside another viewport. Child 2D nodes will display on it, and child Camera3D 3D nodes will render on it too.

Optionally, a viewport can have its own 2D or 3D world, so it doesn't share what it draws with other viewports.

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.

- :ref:`AnisotropicFiltering<enum_Viewport_AnisotropicFiltering>` **get_anisotropic_filtering_level**\ (\ )

Sets the maximum number of samples to take when using anisotropic filtering on textures (as a power of two). A higher sample count will result in sharper textures at oblique angles, but is more expensive to compute. A value of ``0`` forcibly disables anisotropic filtering, even on materials where it is enabled.

The anisotropic filtering level also affects decals and light projectors if they are configured to use anisotropic filtering. See :ref:`ProjectSettings.rendering/textures/decals/filter<class_ProjectSettings_property_rendering/textures/decals/filter>` and :ref:`ProjectSettings.rendering/textures/light_projectors/filter<class_ProjectSettings_property_rendering/textures/light_projectors/filter>`.

\ **Note:** In 3D, for this setting to have an effect, set :ref:`BaseMaterial3D.texture_filter<class_BaseMaterial3D_property_texture_filter>` to :ref:`BaseMaterial3D.TEXTURE_FILTER_LINEAR_WITH_MIPMAPS_ANISOTROPIC<class_BaseMaterial3D_constant_TEXTURE_FILTER_LINEAR_WITH_MIPMAPS_ANISOTROPIC>` or :ref:`BaseMaterial3D.TEXTURE_FILTER_NEAREST_WITH_MIPMAPS_ANISOTROPIC<class_BaseMaterial3D_constant_TEXTURE_FILTER_NEAREST_WITH_MIPMAPS_ANISOTROPIC>` on materials.

\ **Note:** In 2D, for this setting to have an effect, set :ref:`CanvasItem.texture_filter<class_CanvasItem_property_texture_filter>` to :ref:`CanvasItem.TEXTURE_FILTER_LINEAR_WITH_MIPMAPS_ANISOTROPIC<class_CanvasItem_constant_TEXTURE_FILTER_LINEAR_WITH_MIPMAPS_ANISOTROPIC>` or :ref:`CanvasItem.TEXTURE_FILTER_NEAREST_WITH_MIPMAPS_ANISOTROPIC<class_CanvasItem_constant_TEXTURE_FILTER_NEAREST_WITH_MIPMAPS_ANISOTROPIC>` on the :ref:`CanvasItem<class_CanvasItem>` node displaying the texture (or in :ref:`CanvasTexture<class_CanvasTexture>`). However, anisotropic filtering is rarely useful in 2D, so only enable it for textures in 2D if it makes a meaningful visual difference.

Sets scaling 3D mode. Bilinear scaling renders at different resolution to either undersample or supersample the viewport. FidelityFX Super Resolution 1.0, abbreviated to FSR, is an upscaling technology that produces high quality images at fast framerates by using a spatially aware upscaling algorithm. FSR is slightly more expensive than bilinear, but it produces significantly higher image quality. FSR should be used where possible.

Scales the 3D render buffer based on the viewport size uses an image filter specified in :ref:`ProjectSettings.rendering/scaling_3d/mode<class_ProjectSettings_property_rendering/scaling_3d/mode>` to scale the output image to the full viewport size. Values lower than ``1.0`` can be used to speed up 3D rendering at the cost of quality (undersampling). Values greater than ``1.0`` are only valid for bilinear mode and can be used to improve 3D rendering quality at a high performance cost (supersampling). See also :ref:`ProjectSettings.rendering/anti_aliasing/quality/msaa_3d<class_ProjectSettings_property_rendering/anti_aliasing/quality/msaa_3d>` for multi-sample antialiasing, which is significantly cheaper but only smooths the edges of polygons.

When using FSR upscaling, AMD recommends exposing the following values as preset options to users "Ultra Quality: 0.77", "Quality: 0.67", "Balanced: 0.59", "Performance: 0.5" instead of exposing the entire scale.

Sets the screen-space antialiasing method used. Screen-space antialiasing works by selectively blurring edges in a post-process shader. It differs from MSAA which takes multiple coverage samples while rendering objects. Screen-space AA methods are typically faster than MSAA and will smooth out specular aliasing, but tend to make scenes appear blurry.

Controls how much of the original viewport's size should be covered by the 2D signed distance field. This SDF can be sampled in :ref:`CanvasItem<class_CanvasItem>` shaders and is also used for :ref:`GPUParticles2D<class_GPUParticles2D>` collision. Higher values allow portions of occluders located outside the viewport to still be taken into account in the generated signed distance field, at the cost of performance. If you notice particles falling through :ref:`LightOccluder2D<class_LightOccluder2D>`\ s as the occluders leave the viewport, increase this setting.

The percentage is added on each axis and on both sides. For example, with the default :ref:`SDF_OVERSIZE_120_PERCENT<class_Viewport_constant_SDF_OVERSIZE_120_PERCENT>`, the signed distance field will cover 20% of the viewport's size outside the viewport on each side (top, right, bottom, left).

Affects the final texture sharpness by reading from a lower or higher mipmap (also called "texture LOD bias"). Negative values make mipmapped textures sharper but grainier when viewed at a distance, while positive values make mipmapped textures blurrier (even when up close).

Enabling temporal antialiasing (:ref:`use_taa<class_Viewport_property_use_taa>`) will automatically apply a ``-0.5`` offset to this value, while enabling FXAA (:ref:`screen_space_aa<class_Viewport_property_screen_space_aa>`) will automatically apply a ``-0.25`` offset to this value. If both TAA and FXAA are enabled at the same time, an offset of ``-0.75`` is applied to this value.

\ **Note:** If :ref:`scaling_3d_scale<class_Viewport_property_scaling_3d_scale>` is lower than ``1.0`` (exclusive), :ref:`texture_mipmap_bias<class_Viewport_property_texture_mipmap_bias>` is used to adjust the automatic mipmap bias which is calculated internally based on the scale factor.

- |void| **set_use_hdr_2d**\ (\ value\: :ref:`bool<class_bool>`\ )
- :ref:`bool<class_bool>` **is_using_hdr_2d**\ (\ )

If ``true``, 2D rendering will use an high dynamic range (HDR) format framebuffer matching the bit depth of the 3D framebuffer. When using the Forward+ renderer this will be an ``RGBA16`` framebuffer, while when using the Mobile renderer it will be an ``RGB10_A2`` framebuffer. Additionally, 2D rendering will take place in linear color space and will be converted to sRGB space immediately before blitting to the screen (if the Viewport is attached to the screen). Practically speaking, this means that the end result of the Viewport will not be clamped into the ``0-1`` range and can be used in 3D rendering without color space adjustments. This allows 2D rendering to take advantage of effects requiring high dynamic range (e.g. 2D glow) as well as substantially improves the appearance of effects requiring highly detailed gradients.

\ **Note:** This setting will have no effect when using the Compatibility renderer, which always renders in low dynamic range for performance reasons.

If ``true``, :ref:`OccluderInstance3D<class_OccluderInstance3D>` nodes will be usable for occlusion culling in 3D for this viewport. For the root viewport, :ref:`ProjectSettings.rendering/occlusion_culling/use_occlusion_culling<class_ProjectSettings_property_rendering/occlusion_culling/use_occlusion_culling>` must be set to ``true`` instead.

\ **Note:** Enabling occlusion culling has a cost on the CPU. Only enable occlusion culling if you actually plan to use it, and think whether your scene can actually benefit from occlusion culling. Large, open scenes with few or no objects blocking the view will generally not benefit much from occlusion culling. Large open scenes generally benefit more from mesh LOD and visibility ranges (:ref:`GeometryInstance3D.visibility_range_begin<class_GeometryInstance3D_property_visibility_range_begin>` and :ref:`GeometryInstance3D.visibility_range_end<class_GeometryInstance3D_property_visibility_range_end>`) compared to occlusion culling.

Using :ref:`Transform2D.get_scale()<class_Transform2D_method_get_scale>` on the returned value, this can be used to compensate for scaling when zooming a :ref:`Camera2D<class_Camera2D>` node, or to scale down a :ref:`TextureRect<class_TextureRect>` to be pixel-perfect regardless of the automatically computed scale factor.

\ **Note:** Due to how pixel scaling works, the returned transform's X and Y scale may differ slightly, even when :ref:`Window.content_scale_aspect<class_Window_property_content_scale_aspect>` is set to a mode that preserves the pixels' aspect ratio. If :ref:`Window.content_scale_aspect<class_Window_property_content_scale_aspect>` is :ref:`Window.CONTENT_SCALE_ASPECT_IGNORE<class_Window_constant_CONTENT_SCALE_ASPECT_IGNORE>`, the X and Y scale may differ *significantly*.

.. _class_Viewport_method_get_texture:

.. rst-class:: classref-method

:ref:`ViewportTexture<class_ViewportTexture>` **get_texture**\ (\ ) |const| :ref:`🔗<class_Viewport_method_get_texture>`

Returns the viewport's texture.

\ **Note:** When trying to store the current texture (e.g. in a file), it might be completely black or outdated if used too early, especially when used in e.g. :ref:`Node._ready()<class_Node_private_method__ready>`. To make sure the texture you get is correct, you can await :ref:`RenderingServer.frame_post_draw<class_RenderingServer_signal_frame_post_draw>` signal.

::

    func _ready():
        await RenderingServer.frame_post_draw
        $Viewport.get_texture().get_image().save_png("user://Screenshot.png")

\ **Note:** When :ref:`use_hdr_2d<class_Viewport_property_use_hdr_2d>` is ``true`` the returned texture will be an HDR image encoded in linear space.

:ref:`Control<class_Control>` **gui_get_hovered_control**\ (\ ) |const| :ref:`🔗<class_Viewport_method_gui_get_hovered_control>`

Returns the :ref:`Control<class_Control>` that the mouse is currently hovering over in this viewport. If no :ref:`Control<class_Control>` has the cursor, returns ``null``.

Typically the leaf :ref:`Control<class_Control>` node or deepest level of the subtree which claims hover. This is very useful when used together with :ref:`Node.is_ancestor_of()<class_Node_method_is_ancestor_of>` to find if the mouse is within a control tree.

.. _class_Viewport_method_gui_release_focus:

.. rst-class:: classref-method

|void| **gui_release_focus**\ (\ ) :ref:`🔗<class_Viewport_method_gui_release_focus>`

Removes the focus from the currently focused :ref:`Control<class_Control>` within this viewport. If no :ref:`Control<class_Control>` has the focus, does nothing.

.. _class_Viewport_method_is_input_handled:

.. rst-class:: classref-method

:ref:`bool<class_bool>` **is_input_handled**\ (\ ) |const| :ref:`🔗<class_Viewport_method_is_input_handled>`

Returns whether the current :ref:`InputEvent<class_InputEvent>` has been handled. Input events are not handled until :ref:`set_input_as_handled()<class_Viewport_method_set_input_as_handled>` has been called during the lifetime of an :ref:`InputEvent<class_InputEvent>`.

This is usually done as part of input handling methods like :ref:`Node._input()<class_Node_private_method__input>`, :ref:`Control._gui_input()<class_Control_private_method__gui_input>` or others, as well as in corresponding signal handlers.

If :ref:`handle_input_locally<class_Viewport_property_handle_input_locally>` is set to ``false``, this method will try finding the first parent viewport that is set to handle input locally, and return its value for :ref:`is_input_handled()<class_Viewport_method_is_input_handled>` instead.

.. _class_Viewport_method_notify_mouse_entered:

.. rst-class:: classref-method

|void| **notify_mouse_entered**\ (\ ) :ref:`🔗<class_Viewport_method_notify_mouse_entered>`

Inform the Viewport that the mouse has entered its area. Use this function before sending an :ref:`InputEventMouseButton<class_InputEventMouseButton>` or :ref:`InputEventMouseMotion<class_InputEventMouseMotion>` to the **Viewport** with :ref:`push_input()<class_Viewport_method_push_input>`. See also :ref:`notify_mouse_exited()<class_Viewport_method_notify_mouse_exited>`.

\ **Note:** In most cases, it is not necessary to call this function because :ref:`SubViewport<class_SubViewport>` nodes that are children of :ref:`SubViewportContainer<class_SubViewportContainer>` are notified automatically. This is only necessary when interacting with viewports in non-default ways, for example as textures in :ref:`TextureRect<class_TextureRect>` or with an :ref:`Area3D<class_Area3D>` that forwards input events.

.. _class_Viewport_method_notify_mouse_exited:

.. rst-class:: classref-method

|void| **notify_mouse_exited**\ (\ ) :ref:`🔗<class_Viewport_method_notify_mouse_exited>`

Inform the Viewport that the mouse has left its area. Use this function when the node that displays the viewport notices the mouse has left the area of the displayed viewport. See also :ref:`notify_mouse_entered()<class_Viewport_method_notify_mouse_entered>`.

\ **Note:** In most cases, it is not necessary to call this function because :ref:`SubViewport<class_SubViewport>` nodes that are children of :ref:`SubViewportContainer<class_SubViewportContainer>` are notified automatically. This is only necessary when interacting with viewports in non-default ways, for example as textures in :ref:`TextureRect<class_TextureRect>` or with an :ref:`Area3D<class_Area3D>` that forwards input events.

.. _class_Viewport_method_push_input:

|void| **push_input**\ (\ event\: :ref:`InputEvent<class_InputEvent>`, in_local_coords\: :ref:`bool<class_bool>` = false\ ) :ref:`🔗<class_Viewport_method_push_input>`

Triggers the given ``event`` in this **Viewport**. This can be used to pass an :ref:`InputEvent<class_InputEvent>` between viewports, or to locally apply inputs that were sent over the network or saved to a file.

If ``in_local_coords`` is ``false``, the event's position is in the embedder's coordinates and will be converted to viewport coordinates. If ``in_local_coords`` is ``true``, the event's position is in viewport coordinates.

While this method serves a similar purpose as :ref:`Input.parse_input_event()<class_Input_method_parse_input_event>`, it does not remap the specified ``event`` based on project settings like :ref:`ProjectSettings.input_devices/pointing/emulate_touch_from_mouse<class_ProjectSettings_property_input_devices/pointing/emulate_touch_from_mouse>`.

Calling this method will propagate calls to child nodes for following methods in the given order:

- :ref:`Node._input()<class_Node_private_method__input>`\ 

- :ref:`Control._gui_input()<class_Control_private_method__gui_input>` for :ref:`Control<class_Control>` nodes

- :ref:`Node._shortcut_input()<class_Node_private_method__shortcut_input>`\ 

- :ref:`Node._unhandled_key_input()<class_Node_private_method__unhandled_key_input>`\ 

- :ref:`Node._unhandled_input()<class_Node_private_method__unhandled_input>`\ 

If an earlier method marks the input as handled via :ref:`set_input_as_handled()<class_Viewport_method_set_input_as_handled>`, any later method in this list will not be called.

If none of the methods handle the event and :ref:`physics_object_picking<class_Viewport_property_physics_object_picking>` is ``true``, the event is used for physics object picking.

.. rst-class:: classref-method

|void| **push_text_input**\ (\ text\: :ref:`String<class_String>`\ ) :ref:`🔗<class_Viewport_method_push_text_input>`

Helper method which calls the ``set_text()`` method on the currently focused :ref:`Control<class_Control>`, provided that it is defined (e.g. if the focused Control is :ref:`Button<class_Button>` or :ref:`LineEdit<class_LineEdit>`).

**Deprecated:** Use :ref:`push_input()<class_Viewport_method_push_input>` instead.

Triggers the given ``event`` in this **Viewport**. This can be used to pass an :ref:`InputEvent<class_InputEvent>` between viewports, or to locally apply inputs that were sent over the network or saved to a file.

If ``in_local_coords`` is ``false``, the event's position is in the embedder's coordinates and will be converted to viewport coordinates. If ``in_local_coords`` is ``true``, the event's position is in viewport coordinates.

Calling this method will propagate calls to child nodes for following methods in the given order:

- :ref:`Node._shortcut_input()<class_Node_private_method__shortcut_input>`\ 

- :ref:`Node._unhandled_key_input()<class_Node_private_method__unhandled_key_input>`\ 

- :ref:`Node._unhandled_input()<class_Node_private_method__unhandled_input>`\ 

If an earlier method marks the input as handled via :ref:`set_input_as_handled()<class_Viewport_method_set_input_as_handled>`, any later method in this list will not be called.

If none of the methods handle the event and :ref:`physics_object_picking<class_Viewport_property_physics_object_picking>` is ``true``, the event is used for physics object picking.

\ **Note:** This method doesn't propagate input events to embedded :ref:`Window<class_Window>`\ s or :ref:`SubViewport<class_SubViewport>`\ s.

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.
