Properties

binCount: number

Bins per axis. 16 is the usual sweet spot between build time and tree quality.

intersectionCost: number

Relative cost of testing one primitive.

maxLeafPrimitives: number

Most primitives a leaf may hold. The top level uses 1: one instance per leaf.

traversalCost: number

Relative cost of visiting a node (two box tests). Only the ratio to intersectionCost matters.
