SplitHeuristic()

template<typename T >

BVH_ALWAYS_INLINE bvh::v2::SplitHeuristic< T >::SplitHeuristic ( size_t log_cluster_size = 0, T cost_ratio = static_cast<T>(1.) )

inline

Creates an SAH evaluator object, used by top-down builders to determine where to split.

The two parameters are the log of the size of primitive clusters in base 2, and the ratio of the cost of intersecting a node (a ray-box intersection) over the cost of intersecting a primitive.
