Chapter 373: AfterImageNode

Core Idea

Post processing node for creating an after image effect.

damp : Node.<float>: How quickly the after-image fades. A higher value means the after-image persists longer, while a lower value means it fades faster. Should …
textureNode : TextureNode: The texture node that represents the input of the effect.
updateBeforeType : string: The updateBeforeType is set to NodeUpdateType.FRAME since the node renders its effect once per frame in updateBefore().

import { afterImage } from 'three/addons/tsl/display/AfterImageNode.js';

Constructor

Signature
`new AfterImageNode( textureNode : TextureNode, damp : Node.<float> )`

Properties

Property	Description
`.damp : Node.<float>`	How quickly the after-image fades. A higher value means the after-image persists longer, while a lower value means it fades faster. Should be in the range `[0, 1]`.
`.textureNode : TextureNode`	The texture node that represents the input of the effect.
`.updateBeforeType : string`	The `updateBeforeType` is set to `NodeUpdateType.FRAME` since the node renders its effect once per frame in `updateBefore()`.

Methods

Method	Description
`.dispose()`	Frees internal resources. This method should be called when the effect is no longer required.
`.getTextureNode() : PassTextureNode`	Returns the result of the effect as a texture node.
`.setSize( width : number, height : number )`	Sets the size of the effect.
`.setup( builder : NodeBuilder ) : PassTextureNode`	This method is used to setup the effect's TSL code.
`.updateBefore( frame : NodeFrame )`	This method is used to render the effect once per frame.
