Chapter 389: BuiltinNode

Core Idea

The node allows to set values for built-in shader variables. That is required for features like hardware-accelerated vertex clipping.

Key Concepts

• isBuiltinNode : boolean (readonly): This flag can be used for type testing.
• name : string: The name of the built-in shader variable.
