|
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 they don't share what they draw with other viewports.
|
|
If a viewport is a child of a [SubViewportContainer], it will automatically take up its 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.

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.

<constant name="DEBUG_DRAW_SHADOW_ATLAS" value="9" enum="DebugDraw">
|
|
Draws the shadow atlas that stores shadows from [OmniLight3D]s and [SpotLight3D]s in the upper left quadrant of the [Viewport].
|
|
</constant>
|
|
<constant name="DEBUG_DRAW_DIRECTIONAL_SHADOW_ATLAS" value="10" enum="DebugDraw">
|
|
Draws the shadow atlas that stores shadows from [DirectionalLight3D]s in the upper left quadrant of the [Viewport].
|

<constant name="DEBUG_DRAW_SCENE_LUMINANCE" value="11" enum="DebugDraw">
|
|
</constant>
|
|
<constant name="DEBUG_DRAW_SSAO" value="12" enum="DebugDraw">
|
|
Draws the screen-space ambient occlusion texture instead of the scene so that you can clearly see how it is affecting objects. In order for this display mode to work, you must have [member Environment.ssao_enabled] set in your [WorldEnvironment].
|
|
</constant>
|
|
<constant name="DEBUG_DRAW_PSSM_SPLITS" value="13" enum="DebugDraw">
|
|
Colors each PSSM split for the [DirectionalLight3D]s in the scene a different color so you can see where the splits are. In order, they will be colored red, green, blue, and yellow.
|
|
</constant>
|
|
<constant name="DEBUG_DRAW_DECAL_ATLAS" value="14" enum="DebugDraw">
|
|
Draws the decal atlas used by [Decal]s and light projector textures in the upper left quadrant of the [Viewport].

</constant>
|
|
<constant name="DEFAULT_CANVAS_ITEM_TEXTURE_FILTER_NEAREST" value="0" enum="DefaultCanvasItemTextureFilter">
|
|
The texture filter reads from the nearest pixel only. The simplest and fastest method of filtering, but the texture will look pixelized.
|
|
</constant>
|
|
<constant name="DEFAULT_CANVAS_ITEM_TEXTURE_FILTER_LINEAR" value="1" enum="DefaultCanvasItemTextureFilter">
|
|
The texture filter blends between the nearest 4 pixels. Use this when you want to avoid a pixelated style, but do not want mipmaps.
|
|
</constant>
|
|
<constant name="DEFAULT_CANVAS_ITEM_TEXTURE_FILTER_LINEAR_WITH_MIPMAPS" value="2" enum="DefaultCanvasItemTextureFilter">
|
|
The texture filter reads from the nearest pixel in the nearest mipmap. The fastest way to read from textures with mipmaps.
|
|
</constant>
|
|
<constant name="DEFAULT_CANVAS_ITEM_TEXTURE_FILTER_NEAREST_WITH_MIPMAPS" value="3" enum="DefaultCanvasItemTextureFilter">
|
|
The texture filter blends between the nearest 4 pixels and between the nearest 2 mipmaps.
|
|
</constant>
|
|
<constant name="DEFAULT_CANVAS_ITEM_TEXTURE_FILTER_MAX" value="4" enum="DefaultCanvasItemTextureFilter">
|
|
Max value for [enum DefaultCanvasItemTextureFilter] enum.
|
|
</constant>
|
|
<constant name="DEFAULT_CANVAS_ITEM_TEXTURE_REPEAT_DISABLED" value="0" enum="DefaultCanvasItemTextureRepeat">
|
|
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.
|
|
</constant>
|
|
<constant name="DEFAULT_CANVAS_ITEM_TEXTURE_REPEAT_ENABLED" value="1" enum="DefaultCanvasItemTextureRepeat">
|
|
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.
|
|
</constant>
|
|
<constant name="DEFAULT_CANVAS_ITEM_TEXTURE_REPEAT_MIRROR" value="2" enum="DefaultCanvasItemTextureRepeat">
|
|
Flip the texture when repeating so that the edge lines up instead of abruptly changing.
|
|
</constant>
|
|
<constant name="DEFAULT_CANVAS_ITEM_TEXTURE_REPEAT_MAX" value="3" enum="DefaultCanvasItemTextureRepeat">
|
|
Max value for [enum DefaultCanvasItemTextureRepeat] enum.
