- This class can only be used in combination with

- <code>
- const pixelRatio = window.devicePixelRatio;
- const textureSize = 128 * pixelRatio;
- // instantiate a framebuffer texture
- const frameTexture = new FramebufferTexture( textureSize, textureSize );
- // calculate start position for copying part of the frame data
- const vector = new Vector2();
- vector.x = ( window.innerWidth * pixelRatio / 2 ) - ( textureSize / 2 );
- vector.y = ( window.innerHeight * pixelRatio / 2 ) - ( textureSize / 2 );
- // render the scene
- renderer.clear();
- renderer.render( scene, camera );
- // copy part of the rendered frame into the framebuffer texture
- renderer.copyFramebufferToTexture( frameTexture, vector );

- <h2>Examples</h2>
- <p>[example:webgl_framebuffer_texture]</p>
- <h2>Constructor</h2>
- <h3>
- [name]( [param:Number width], [param:Number height] )
- </h3>
- <p>
- [page:Number width] -- The width of the texture.<br />
- [page:Number height] -- The height of the texture.
- </p>
- <h2>Properties</h2>
- <p>See the base [page:Texture Texture] class for common properties.</p>
- <h3>[property:Boolean generateMipmaps]</h3>
- <p>Whether to generate mipmaps for the [name]. Default value is `false`.</p>
- <h3>[property:Boolean isFramebufferTexture]</h3>
- <p>Read-only flag to check if a given object is of type [name].</p>
- <h3>[property:number magFilter]</h3>
- <p>
- How the texture is sampled when a texel covers more than one pixel. The
- default is [page:Textures THREE.NearestFilter], which uses the value of
- the closest texel.
- <br /><br />
- See [page:Textures texture constants] for details.
- </p>
- <h3>[property:number minFilter]</h3>
- <p>
- How the texture is sampled when a texel covers less than one pixel. The
- default is [page:Textures THREE.NearestFilter], which uses the value of
- the closest texel.
- <br /><br />
- See [page:Textures texture constants] for details.
- </p>
- <h3>[property:Boolean needsUpdate]</h3>
- <p>True by default. This is required so that the canvas data is loaded.</p>
