<h1>[name]</h1>

<p class="desc">
|
||
|
|
A special render target that enables a fragment shader to write to several textures.
|
||
|
|
This approach is useful for advanced rendering techniques like post-processing or deferred rendering.
|
||
|
|
|
||
|
|
Heads up: [name] can only be used with a WebGL 2 rendering context.

<h2>Examples</h2>
|
||
|
|
|
||
|
|
<p>
|
||
|
|
[example:webgl2_multiple_rendertargets webgl2 / multiple / rendertargets ]

<h2>Constructor</h2>
|
||
|
|
|
||
|
|
|
||
|
|
<h3>[name]([param:Number width], [param:Number height], [param:Number count])</h3>
|
||
|
|
|
||
|
|
<p>
|
||
|
|
[page:Number width] - The width of the render target. Default is `1`.<br />
|
||
|
|
[page:Number height] - The height of the render target. Default is `1`.<br />
|
||
|
|
[page:Number count] - The number of render targets. Default is `1`.
|
||
|
|
</p>
|
||
|
|
|
||
|
|
<h2>Properties</h2>
|
||
|
|
|
||
|
|
<h3>[property:Boolean isWebGLMultipleRenderTargets]</h3>
|
||
|
|
<p>
|
||
|
|
Read-only flag to check if a given object is of type [name].
|
||
|
|
</p>
|
||
|
|
|
||
|
|
<h3>[property:Array texture]</h3>
|
||
|
|
<p>
|
||
|
|
The texture property is overwritten in [name] and replaced with an array. This array holds the [page:WebGLRenderTarget.texture texture]
|
||
|
|
references of the respective render targets.
