`Static`build

build(meshes: MeshWithBounds[]): BVH
Build BVH from meshes
Parameters
- meshes: MeshWithBounds[]
Returns BVH

`Static`buildAsync

buildAsync(
    meshes: MeshWithBounds[],
    budgetMs: number,
    yieldToEventLoop: () => Promise<void>,
): Promise<BVH>
Build the same tree in chunks so large models do not occupy one event-loop turn.
Parameters
- meshes: MeshWithBounds[]
- budgetMs: number
- yieldToEventLoop: () => Promise<void>
Returns Promise<BVH>
