    Interface StaticMergePlan

    What mergeStaticGeometry decided.

    interface StaticMergePlan {
        groups: readonly StaticMergeGroup[];
        instanceCount: number;
        instanced: Uint32Array;
        meshNeeded: Uint8Array;
    }
    Index
    groups: readonly StaticMergeGroup[]
    instanceCount: number

    Length of the instance array the plan was made for.

    instanced: Uint32Array

    Positions (in the input array) of the instances that stay normal instances, in input order.

    meshNeeded: Uint8Array

    Per input mesh: 1 when a normal instance uses it, so it needs its own tree; 0 when only merged sources use it.
