TAARenderPass

Temporal Anti-Aliasing Render Pass.

When there is no motion in the scene, the TAA render pass accumulates jittered camera samples across frames to create a high quality anti-aliased result.

Note: This effect uses no reprojection so it is no TRAA implementation.

Code Example

const taaRenderPass = new TAARenderPass( scene, camera );
taaRenderPass.unbiased = false;
composer.addPass( taaRenderPass );

Import

TAARenderPass is an addon, and must be imported explicitly, see Installation#Addons.

import { TAARenderPass } from 'three/addons/postprocessing/TAARenderPass.js';

Constructor

new TAARenderPass( scene : Scene, camera : Camera, clearColor : number | Color | string, clearAlpha : number )

Constructs a new TAA render pass.

scene

The scene to render.
camera

The camera.
clearColor

The clear color of the render pass.

Default is 0x000000.
clearAlpha

The clear alpha of the render pass.

Default is 0.

Properties

.accumulate : boolean

Whether to accumulate frames or not. This enables the TAA.

Default is false.

.accumulateIndex : number

The accumulation index.

Default is -1.

.sampleLevel : number

Overwritten and set to 0 by default.

Default is 0.

Overrides: SSAARenderPass#sampleLevel

Methods

.dispose()

Frees the GPU-related resources allocated by this instance. Call this method whenever the pass is no longer used in your app.

Overrides: SSAARenderPass#dispose

.render( renderer : WebGLRenderer, writeBuffer : WebGLRenderTarget, readBuffer : WebGLRenderTarget, deltaTime : number, maskActive : boolean )

Performs the TAA render pass.

renderer

The renderer.
writeBuffer

The write buffer. This buffer is intended as the rendering destination for the pass.
readBuffer

The read buffer. The pass can access the result from the previous pass from this buffer.
deltaTime

The delta time in seconds.
maskActive

Whether masking is active or not.
Overrides: SSAARenderPass#render
