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
