Chapter 434: MaxMipLevelNode

Core Idea

A special type of uniform node that computes the maximum mipmap level for a given texture node.

Key Concepts

• texture : Texture (readonly): The texture.
• textureNode : TextureNode (readonly): The texture node to compute the max mip level for.
• updateType : string: The updateType is set to NodeUpdateType.FRAME since the node updates the texture once per frame in its [MaxMipLevelNode#update](MaxMipL…

Code Examples

const level = maxMipLevel( textureNode );

• What it demonstrates: Typical usage of MaxMipLevelNode.

Reference Tables

Constructor

Signature
new MaxMipLevelNode( textureNode : TextureNode )

Properties

Property	Description
.texture : Texture (readonly)	The texture.
.textureNode : TextureNode (readonly)	The texture node to compute the max mip level for.
.updateType : string	The updateType is set to NodeUpdateType.FRAME since the node updates the texture once per frame in its MaxMipLevelNode#update method.

Key Takeaways

1. MaxMipLevelNode extends: EventDispatcher → Node → InputNode → UniformNode
2. Most relevant properties: texture, textureNode, updateType.
