Server for anything visible. The visual server is the API backend for everything visible. The whole scene system mounts on it to display.
The visual server is completely opaque, the internals are entirely implementation specific and cannot be accessed.
The visual server can be used to bypass the scene system entirely.
Resources are created using the [code]*_create[/code] functions.
All objects are drawn to a viewport. You can use the [Viewport] attached to the [SceneTree] or you can create one yourself with [method viewport_create]. When using a custom scenario or canvas, the scenario or canvas needs to be attached to the viewport using [method viewport_set_scenario] or [method viewport_attach_canvas].
In 3D, all visual objects must be associated with a scenario. The scenario is a visual representation of the world. If accessing the visual server from a running game, the scenario can be accessed from the scene tree from any [Spatial] node with [method Spatial.get_world]. Otherwise, a scenario can be created with [method scenario_create].
Similarly, in 2D, a canvas is needed to draw all canvas items.
In 3D, all visible objects are comprised of a resource and an instance. A resource can be a mesh, a particle system, a light, or any other 3D object. In order to be visible resources must be attached to an instance using [method instance_set_base]. The instance must also be attached to the scenario using [method instance_set_scenario] in order to be visible.
In 2D, all visible objects are some form of canvas item. In order to be visible, a canvas item needs to be the child of a canvas attached to a viewport, or it needs to be the child of another canvas item that is eventually attached to the canvas.
Sets margin size, where black bars (or images, if [method black_bars_set_images] was used) are rendered.

<methodname="set_shader_async_hidden_forbidden">
<returntype="void"/>
<argumentindex="0"name="forbidden"type="bool"/>
<description>
If asynchronous shader compilation is enabled, this controls whether [constant SpatialMaterial.ASYNC_MODE_HIDDEN] is obeyed.

<argumentindex="0"name="texture"type="RID"/>
<argumentindex="1"name="flags"type="int"/>
<description>
Sets the texture's flags. See [enum TextureFlags] for options.
Copies viewport to a region of the screen specified by [code]rect[/code]. If [member Viewport.render_direct_to_screen] is [code]true[/code], then viewport does not use a framebuffer and the contents of the viewport are rendered directly to screen. However, note that the root viewport is drawn last, therefore it will draw over the screen. Accordingly, you must set the root viewport to an area that does not cover the area that you have attached this viewport to.
For example, you can set the root viewport to not render at all with the following code:
Using this can result in significant optimization, especially on lower-end devices. However, it comes at the cost of having to manage your viewports manually. For a further optimization see, [method viewport_set_render_direct_to_screen].

</method>
<methodname="viewport_create">
<returntype="RID"/>
<description>
Creates an empty viewport and adds it to the VisualServer. It can be accessed with the RID that is returned. This RID will be used in all [code]viewport_*[/code] VisualServer functions.
Once finished with your RID, you will want to free the RID using the VisualServer's [method free_rid] static method.
If [code]true[/code], render the contents of the viewport directly to screen. This allows a low-level optimization where you can skip drawing a viewport to the root viewport. While this optimization can result in a significant increase in speed (especially on older devices), it comes at a cost of usability. When this is enabled, you cannot read from the viewport or from the [code]SCREEN_TEXTURE[/code]. You also lose the benefit of certain window settings, such as the various stretch modes. Another consequence to be aware of is that in 2D the rendering happens in window coordinates, so if you have a viewport that is double the size of the window, and you set this, then only the portion that fits within the window will be drawn, no automatic scaling is possible, even if your game scene is significantly larger than the window size.

</method>
<methodname="viewport_set_scenario">
<returntype="void"/>
<argumentindex="0"name="viewport"type="RID"/>
<argumentindex="1"name="scenario"type="RID"/>
<description>

</method>
<methodname="viewport_set_sharpen_intensity">
<returntype="void"/>
<argumentindex="0"name="viewport"type="RID"/>
<argumentindex="1"name="intensity"type="float"/>
<description>
Sets the sharpening [code]intensity[/code] for the [code]viewport[/code]. If set to a value greater than [code]0.0[/code], contrast-adaptive sharpening will be applied to the 3D viewport. This has a low performance cost and can be used to recover some of the sharpness lost from using FXAA. Values around [code]0.5[/code] generally give the best results. See also [method viewport_set_use_fxaa].
Sets the viewport's 2D/3D mode. See [enum ViewportUsage] constants for options.

</method>
<methodname="viewport_set_use_debanding">
<returntype="void"/>
<argumentindex="0"name="viewport"type="RID"/>
<argumentindex="1"name="debanding"type="bool"/>
<description>
If [code]true[/code], uses a fast post-processing filter to make banding significantly less visible. 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.
[b]Note:[/b] Only available on the GLES3 backend. [member Viewport.hdr] must also be [code]true[/code] for debanding to be effective.

</method>
<methodname="viewport_set_use_fxaa">
<returntype="void"/>
<argumentindex="0"name="viewport"type="RID"/>
<argumentindex="1"name="fxaa"type="bool"/>
<description>
Enables fast approximate antialiasing for this viewport. 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 [method viewport_set_sharpen_intensity]).

</method>
<methodname="viewport_set_vflip">
<returntype="void"/>
<argumentindex="0"name="viewport"type="RID"/>
<argumentindex="1"name="enabled"type="bool"/>
<description>
If [code]true[/code], the viewport's rendering is flipped vertically.
If [code]false[/code], disables rendering completely, but the engine logic is still being processed. You can call [method force_draw] to draw a frame even with rendering disabled.

Draw all objects in a way that displays how much overdraw is occurring. Overdraw occurs when a section of pixels is drawn and shaded and then another object covers it up. To optimize a scene, you should reduce overdraw.
Registered changes which have low priority can be optionally prevented from causing editor redraws. Examples might include dynamic shaders (typically using the [code]TIME[/code] built-in).
