Chapter 451: PixelationNode

Core Idea

A inner node definition that implements the actual pixelation TSL code.

Key Concepts

• depthEdgeStrength : Node.<float>: The depth edge strength.
• depthNode : TextureNode: The texture that represents the beauty's depth.
• normalEdgeStrength : Node.<float>: The pixel size.
• normalNode : TextureNode: The texture that represents the beauty's normals.
• pixelSize : Node.<float>: The pixel size.
• textureNode : TextureNode: The texture node that represents the beauty pass.
• updateType : string: The updateType is set to NodeUpdateType.FRAME since the node updates its internal uniforms once per frame in updateBefore().

Constructor

Signature
new PixelationNode( textureNode : TextureNode, depthNode : TextureNode, normalNode : TextureNode, pixelSize : Node.<float>, normalEdgeStrength : Node.<float>, depthEdgeStrength : Node.<float> )

Properties

Property	Description
.depthEdgeStrength : Node.<float>	The depth edge strength.
.depthNode : TextureNode	The texture that represents the beauty's depth.
.normalEdgeStrength : Node.<float>	The pixel size.
.normalNode : TextureNode	The texture that represents the beauty's normals.
.pixelSize : Node.<float>	The pixel size.
.textureNode : TextureNode	The texture node that represents the beauty pass.
.updateType : string	The updateType is set to NodeUpdateType.FRAME since the node updates its internal uniforms once per frame in updateBefore().

Methods

Method	Description
.setup( builder : NodeBuilder ) : ShaderCallNodeInternal	This method is used to setup the effect's TSL code.
.update( frame : NodeFrame )	This method is used to update uniforms once per frame.

Key Takeaways

1. PixelationNode extends: EventDispatcher → Node → TempNode
2. Most relevant properties: depthEdgeStrength, depthNode, normalEdgeStrength, normalNode.
3. Key methods: setup, update.
