Import
TRAANode is an addon, and must be imported explicitly, see Installation#Addons.
import { traa } from 'three/addons/tsl/display/TRAANode.js';Constructor
new TRAANode( beautyNode : TextureNode, depthNode : TextureNode, velocityNode : TextureNode, camera : Camera )
Constructs a new TRAA node.
| beautyNode |
The texture node that represents the input of the effect. |
| depthNode |
A node that represents the scene's depth. |
| velocityNode |
A node that represents the scene's velocity. |
| camera |
The camera the scene is rendered with. |
Properties
.beautyNode : TextureNode
The texture node that represents the input of the effect.
.depthNode : TextureNode
A node that represents the scene's velocity.
.depthThreshold : number
When the difference between the current and previous depth goes above this threshold, the history is considered invalid.
Default is 0.0005.
.edgeDepthDiff : number
The depth difference within the 3×3 neighborhood to consider a pixel as an edge.
Default is 0.001.
.isTRAANode : boolean (readonly)
This flag can be used for type testing.
Default is true.
.maxVelocityLength : number
The history becomes invalid as the pixel length of the velocity approaches this value.
Default is 128.
.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
.useSubpixelCorrection : boolean
Whether to decrease the weight on the current frame when the velocity is more subpixel. This reduces blurriness under motion, but can introduce a square pattern artifact.
Default is true.
.velocityNode : TextureNode
A node that represents the scene's velocity.
Methods
.clearViewOffset()
Clears the view offset from the scene's camera.
.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. |
.setViewOffset( width : number, height : number )
Defines the TRAA's current jitter as a view offset to the scene's camera.
| 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 render targets and 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. |
- Overrides: TempNode#updateBefore
