Viewport

Inherits: Node < Object

Inherited By: SubViewport, 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. Children 2D Nodes will display on it, and children 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.

Represents the size of the PositionalShadowAtlasQuadrantSubdiv enum.

enum Scaling3DMode:

Scaling3DMode SCALING_3D_MODE_BILINEAR = 0

Use bilinear scaling for the viewport’s 3D buffer. The amount of scaling can be set using scaling_3d_scale. Values less than 1.0 will result in undersampling while values greater than 1.0 will result in supersampling. A value of 1.0 disables scaling.

Scaling3DMode SCALING_3D_MODE_FSR = 1

Use AMD FidelityFX Super Resolution 1.0 upscaling for the viewport’s 3D buffer. The amount of scaling can be set using scaling_3d_scale. Values less than 1.0 will be result in the viewport being upscaled using FSR. Values greater than 1.0 are not supported and bilinear downsampling will be used instead. A value of 1.0 disables scaling.

Scaling3DMode SCALING_3D_MODE_MAX = 2

Represents the size of the Scaling3DMode enum.

enum MSAA:

MSAA MSAA_DISABLED = 0

Multisample antialiasing mode disabled. This is the default value, and is also the fastest setting.

DebugDraw DEBUG_DRAW_MOTION_VECTORS = 25

enum DefaultCanvasItemTextureFilter:

DefaultCanvasItemTextureFilter DEFAULT_CANVAS_ITEM_TEXTURE_FILTER_NEAREST = 0

The texture filter reads from the nearest pixel only. The simplest and fastest method of filtering, but the texture will look pixelized.

Max value for DefaultCanvasItemTextureFilter enum.

enum DefaultCanvasItemTextureRepeat:

DefaultCanvasItemTextureRepeat DEFAULT_CANVAS_ITEM_TEXTURE_REPEAT_DISABLED = 0

Disables textures repeating. Instead, when reading UVs outside the 0-1 range, the value will be clamped to the edge of the texture, resulting in a stretched out look at the borders of the texture.

DefaultCanvasItemTextureRepeat DEFAULT_CANVAS_ITEM_TEXTURE_REPEAT_ENABLED = 1

Enables the texture to repeat when UV coordinates are outside the 0-1 range. If using one of the linear filtering modes, this can result in artifacts at the edges of a texture when the sampler filters across the edges of the texture.

Flip the texture when repeating so that the edge lines up instead of abruptly changing.

DefaultCanvasItemTextureRepeat DEFAULT_CANVAS_ITEM_TEXTURE_REPEAT_MAX = 3

float fsr_sharpness = 0.2

• void set_fsr_sharpness ( float value )

• float get_fsr_sharpness ( )

Determines how sharp the upscaled image will be when using the FSR upscaling mode. Sharpness halves with every whole number. Values go from 0.0 (sharpest) to 2.0. Values above 2.0 won’t make a visible difference.

To control this property on the root viewport, set the ProjectSettings.rendering/scaling_3d/fsr_sharpness project setting.

Transform2D global_canvas_transform

• void set_global_canvas_transform ( Transform2D value )

• Transform2D get_global_canvas_transform ( )

The global canvas transform of the viewport. The canvas transform is relative to this.

• void set_disable_input ( bool value )

• bool is_input_disabled ( )

If true, the viewport will not receive input events.

bool gui_embed_subwindows = false

• void set_embedding_subwindows ( bool value )

bool gui_snap_controls_to_pixels = true

• void set_snap_controls_to_pixels ( bool value )

• bool is_snap_controls_to_pixels_enabled ( )

If true, the GUI controls on the viewport will lay pixel perfectly.

bool handle_input_locally = true

The automatic LOD bias to use for meshes rendered within the Viewport (this is analogous to ReflectionProbe.mesh_lod_threshold). Higher values will use less detailed versions of meshes that have LOD variations generated. If set to 0.0, automatic LOD is disabled. Increase mesh_lod_threshold to improve performance at the cost of geometry detail.

To control this property on the root viewport, set the ProjectSettings.rendering/mesh_lod/lod_change/threshold_pixels project setting.

Note: mesh_lod_threshold does not affect GeometryInstance3D visibility ranges (also known as “manual” LOD or hierarchical LOD).

MSAA msaa_2d = 0

• void set_msaa_2d ( MSAA value )

• MSAA get_msaa_2d ( )

The multisample anti-aliasing mode for 2D/Canvas rendering. A higher number results in smoother edges at the cost of significantly worse performance. A value of 2 or 4 is best unless targeting very high-end systems. This has no effect on shader-induced aliasing or texture aliasing.

MSAA msaa_3d = 0

• void set_msaa_3d ( MSAA value )

• MSAA get_msaa_3d ( )

The multisample anti-aliasing mode for 3D rendering. A higher number results in smoother edges at the cost of significantly worse performance. A value of 2 or 4 is best unless targeting very high-end systems. See also bilinear scaling 3d scaling_3d_mode for supersampling, which provides higher quality but is much more expensive. This has no effect on shader-induced aliasing or texture aliasing.

bool own_world_3d = false

• void set_use_own_world_3d ( bool value )

• bool is_using_own_world_3d ( )

If true, the viewport will use a unique copy of the World3D defined in world_3d.

bool physics_object_picking = false

• void set_physics_object_picking ( bool value )

• bool get_physics_object_picking ( )

If true, the objects rendered by viewport become subjects of mouse picking process.

bool physics_object_picking_sort = false

• void set_physics_object_picking_sort ( bool value )

• bool get_physics_object_picking_sort ( )

If true, objects receive mouse picking events sorted primarily by their CanvasItem.z_index and secondarily by their position in the scene tree. If false, the order is undetermined.

Note: This setting is disabled by default because of its potential expensive computational cost.

bool positional_shadow_atlas_16_bits = true

• void set_positional_shadow_atlas_16_bits ( bool value )

• bool get_positional_shadow_atlas_16_bits ( )

Use 16 bits for the omni/spot shadow depth map. Enabling this results in shadows having less precision and may result in shadow acne, but can lead to performance improvements on some devices.

PositionalShadowAtlasQuadrantSubdiv positional_shadow_atlas_quad_0 = 2

• void set_positional_shadow_atlas_quadrant_subdiv ( int quadrant, PositionalShadowAtlasQuadrantSubdiv subdiv )

• PositionalShadowAtlasQuadrantSubdiv get_positional_shadow_atlas_quadrant_subdiv ( int quadrant ) const

The subdivision amount of the first quadrant on the shadow atlas.

PositionalShadowAtlasQuadrantSubdiv positional_shadow_atlas_quad_1 = 2

• void set_positional_shadow_atlas_quadrant_subdiv ( int quadrant, PositionalShadowAtlasQuadrantSubdiv subdiv )

• PositionalShadowAtlasQuadrantSubdiv get_positional_shadow_atlas_quadrant_subdiv ( int quadrant ) const

The subdivision amount of the second quadrant on the shadow atlas.

PositionalShadowAtlasQuadrantSubdiv positional_shadow_atlas_quad_2 = 3

• void set_positional_shadow_atlas_quadrant_subdiv ( int quadrant, PositionalShadowAtlasQuadrantSubdiv subdiv )

• PositionalShadowAtlasQuadrantSubdiv get_positional_shadow_atlas_quadrant_subdiv ( int quadrant ) const

The subdivision amount of the third quadrant on the shadow atlas.

PositionalShadowAtlasQuadrantSubdiv positional_shadow_atlas_quad_3 = 4

• void set_positional_shadow_atlas_quadrant_subdiv ( int quadrant, PositionalShadowAtlasQuadrantSubdiv subdiv )

• PositionalShadowAtlasQuadrantSubdiv get_positional_shadow_atlas_quadrant_subdiv ( int quadrant ) const

The subdivision amount of the fourth quadrant on the shadow atlas.

int positional_shadow_atlas_size = 2048

• void set_positional_shadow_atlas_size ( int value )

• int get_positional_shadow_atlas_size ( )

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

Note: If this is set to 0, no positional shadows will be visible at all. This can improve performance significantly on low-end systems by reducing both the CPU and GPU load (as fewer draw calls are needed to draw the scene without shadows).

Scaling3DMode scaling_3d_mode = 0

• void set_scaling_3d_mode ( Scaling3DMode value )

• Scaling3DMode get_scaling_3d_mode ( )

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.

To control this property on the root viewport, set the ProjectSettings.rendering/scaling_3d/mode project setting.

float scaling_3d_scale = 1.0

• void set_scaling_3d_scale ( float value )

• float get_scaling_3d_scale ( )

Scales the 3D render buffer based on the viewport size uses an image filter specified in ProjectSettings.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 ProjectSettings.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.

To control this property on the root viewport, set the ProjectSettings.rendering/scaling_3d/scale project setting.

ScreenSpaceAA screen_space_aa = 0

• void set_screen_space_aa ( ScreenSpaceAA value )

• ScreenSpaceAA get_screen_space_aa ( )

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.

SDFOversize sdf_oversize = 1

• void set_sdf_oversize ( SDFOversize value )

• SDFOversize get_sdf_oversize ( )

There is currently no description for this property. Please help us by contributing one!

SDFScale sdf_scale = 1

• void set_sdf_scale ( SDFScale value )

• SDFScale get_sdf_scale ( )

There is currently no description for this property. Please help us by contributing one!

bool snap_2d_transforms_to_pixel = false

• void set_snap_2d_transforms_to_pixel ( bool value )

• bool is_snap_2d_transforms_to_pixel_enabled ( )

There is currently no description for this property. Please help us by contributing one!

bool snap_2d_vertices_to_pixel = false

• void set_snap_2d_vertices_to_pixel ( bool value )

• bool is_snap_2d_vertices_to_pixel_enabled ( )

There is currently no description for this property. Please help us by contributing one!

float texture_mipmap_bias = 0.0

• void set_texture_mipmap_bias ( float value )

• float get_texture_mipmap_bias ( )

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 (use_taa) will automatically apply a -0.5 offset to this value, while enabling FXAA (screen_space_aa) will automatically apply a -0.25 offset to this value. If both TAA and FXAA are enbled at the same time, an offset of -0.75 is applied to this value.

Note: If scaling_3d_scale is lower than 1.0 (exclusive), texture_mipmap_bias is used to adjust the automatic mipmap bias which is calculated internally based on the scale factor. The formula for this is log2(scaling_3d_scale) + mipmap_bias.

To control this property on the root viewport, set the ProjectSettings.rendering/textures/default_filters/texture_mipmap_bias project setting.

bool transparent_bg = false

• void set_transparent_background ( bool value )

• bool has_transparent_background ( )

If true, the viewport should render its background as transparent.

bool use_debanding = false

• void set_use_debanding ( bool value )

• bool is_using_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 Environment.background_mode is Environment.BG_CANVAS. See also ProjectSettings.rendering/anti_aliasing/quality/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.

bool use_occlusion_culling = false

• void set_use_occlusion_culling ( bool value )

• bool is_using_occlusion_culling ( )

If true, OccluderInstance3D nodes will be usable for occlusion culling in 3D for this viewport. For the root viewport, ProjectSettings.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 (GeometryInstance3D.visibility_range_begin and GeometryInstance3D.visibility_range_end) compared to occlusion culling.

bool use_taa = false

• void set_use_taa ( bool value )

• bool is_using_taa ( )

Enables Temporal Anti-Aliasing for this viewport. TAA works by jittering the camera and accumulating the images of the last rendered frames, motion vector rendering is used to account for camera and object motion.

Note: The implementation is not complete yet, some visual instances such as particles and skinned meshes may show artifacts.

bool use_xr = false

• void set_use_xr ( bool value )

• bool is_using_xr ( )

If true, the viewport will use the primary XR interface to render XR output. When applicable this can result in a stereoscopic image and the resulting render being output to a headset.

VRSMode vrs_mode = 0

• void set_vrs_mode ( VRSMode value )

• VRSMode get_vrs_mode ( )

The Variable Rate Shading (VRS) mode that is used for this viewport. Note, if hardware does not support VRS this property is ignored.

Texture2D vrs_texture

• void set_vrs_texture ( Texture2D value )

• Texture2D get_vrs_texture ( )

Texture to use when vrs_mode is set to VRS_TEXTURE.

The texture must use a lossless compression format so that colors can be matched precisely. The following VRS densities are mapped to various colors, with brighter colors representing a lower level of shading precision:

- 1x1 = rgb(0, 0, 0)     - #000000
- 1x2 = rgb(0, 85, 0)    - #005500
- 2x1 = rgb(85, 0, 0)    - #550000
- 2x2 = rgb(85, 85, 0)   - #555500
- 2x4 = rgb(85, 170, 0)  - #55aa00
- 4x2 = rgb(170, 85, 0)  - #aa5500
- 4x4 = rgb(170, 170, 0) - #aaaa00
- 4x8 = rgb(170, 255, 0) - #aaff00 - Not supported on most hardware
- 8x4 = rgb(255, 170, 0) - #ffaa00 - Not supported on most hardware
- 8x8 = rgb(255, 255, 0) - #ffff00 - Not supported on most hardware

Returns the drag data from the GUI, that was previously returned by Control._get_drag_data.

Control gui_get_focus_owner ( )

Returns the Control having the focus within this viewport. If no Control has the focus, returns null.

bool gui_is_drag_successful ( ) const

Returns true if the drag operation is successful.

bool gui_is_dragging ( ) const

Returns true if the viewport is currently performing a drag operation.

Alternative to Node.NOTIFICATION_DRAG_BEGIN and Node.NOTIFICATION_DRAG_END when you prefer polling the value.

void gui_release_focus ( )

Removes the focus from the currently focused Control within this viewport. If no Control has the focus, does nothing.

bool is_input_handled ( ) const

Returns whether the current InputEvent has been handled. Input events are not handled until set_input_as_handled has been called during the lifetime of an InputEvent.

This is usually done as part of input handling methods like Node._input, Control._gui_input or others, as well as in corresponding signal handlers.

If 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 is_input_handled instead.

void push_input ( InputEvent event, bool in_local_coords=false )

Triggers the given event in this Viewport. This can be used to pass an 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 Input.parse_input_event, it does not remap the specified event based on project settings like ProjectSettings.input_devices/pointing/emulate_touch_from_mouse.

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

• Node._input

• Control._gui_input for Control nodes

If an earlier method marks the input as handled via set_input_as_handled, any later method in this list will not be called.

void push_text_input ( String text )

Helper method which calls the set_text() method on the currently focused Control, provided that it is defined (e.g. if the focused Control is Button or LineEdit).

void push_unhandled_input ( InputEvent event, bool in_local_coords=false )

Triggers the given InputEvent in this Viewport. This can be used to pass input events 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 Input.parse_input_event, it does not remap the specified event based on project settings like ProjectSettings.input_devices/pointing/emulate_touch_from_mouse.

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

• Node._shortcut_input

• Node._unhandled_input

• Node._unhandled_key_input

If an earlier method marks the input as handled via set_input_as_handled, any later method in this list will not be called.

If none of the methods handle the event and physics_object_picking is true, the event is used for physics object picking.

void set_canvas_cull_mask_bit ( int layer, bool enable )

Set/clear individual bits on the rendering layer mask. This simplifies editing this Viewport‘s layers.

void set_input_as_handled ( )

Stops the input from propagating further down the SceneTree.

Note: This does not affect the methods in Input, only the way events are propagated.

void set_positional_shadow_atlas_quadrant_subdiv ( int quadrant, PositionalShadowAtlasQuadrantSubdiv 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.

void warp_mouse ( Vector2 position )

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

Note: warp_mouse is only supported on Windows, macOS and Linux. It has no effect on Android, iOS and Web.
