StructuralUid

The structural UID of a node buffer, construct-scene-evaluator §EV-A9.1.

In the namespace construct::shader. Declared in src/libs/libconstruct/construct/shader/SpecializedWalkEmitter.hpp.

Detailed description

A hash of what the walk's ORDER depends on, per node: the node type, the definition index, the operation type, the flags and the child links; and the start nodes in their order, and salt: what else changes the emitted walk for one structure, the stack depth and the pop budget. It never hashes a parameter, a material, a transform or a smooth radius: two scenes that differ only in values share one UID and one specialized shader.
