Chapter 237: TextureSizeNode

Core Idea

A node that represents the dimensions of a texture. The texture size is retrieved in the shader via built-in shader functions like textureDimensions() or textureSize().

Key Concepts

• isTextureSizeNode : boolean (readonly): This flag can be used for type testing.
• levelNode : Node.<int>: A level node which defines the requested mip.
• textureNode : TextureNode: A texture node which size should be retrieved.

Constructor

Signature
new TextureSizeNode( textureNode : TextureNode, levelNode : Node.<int> )

Properties

Property	Description
.isTextureSizeNode : boolean (readonly)	This flag can be used for type testing.
.levelNode : Node.<int>	A level node which defines the requested mip.
.textureNode : TextureNode	A texture node which size should be retrieved.

Key Takeaways

1. TextureSizeNode extends: EventDispatcher → Node
2. Most relevant properties: isTextureSizeNode, levelNode, textureNode.
