AfterImageNode

Post processing node for creating an after image effect.

Import

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

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

Constructor

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

Constructs a new after image node.

textureNode | The texture node that represents the input of the effect.
---|---
damp | The damping intensity. A higher value means a stronger after image effect. Default is 0.96.

Properties

.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().

Default is 'frame'.

Overrides: TempNode#updateBeforeType

Methods

.dispose()

Frees internal resources. This method should be called when the effect is no longer required.

Overrides: TempNode#dispose

.getTextureNode() : PassTextureNode

Returns the result of the effect as a texture node.

Returns: A texture node that represents the result of the effect.

.setSize( width : number, height : number )

Sets the size of the effect.

width | The width of the effect.
---|---
height | The height of the effect.

.setup( builder : NodeBuilder ) : PassTextureNode

This method is used to setup the effect's TSL code.

builder | The current node builder.
---|---

Overrides: TempNode#setup

.updateBefore( frame : NodeFrame )

This method is used to render the effect once per frame.

frame | The current node frame.
