Trait ncollide3d::partitioning::BVTCostFn[−][src]

pub trait BVTCostFn<N, B, BV> {
    type UserData;
    fn compute_bv_cost(&mut self, _: &BV) -> Option<N>;
    fn compute_b_cost(&mut self, _: &B) -> Option<(N, Self::UserData)>;
}

Trait implemented by cost functions used by the best-first search on a BVT.

Associated Types

`type UserData`

User-defined data attached to each BVT leaf.

Required Methods

`fn compute_bv_cost(&mut self, _: &BV) -> Option<N>`

Computes the cost of a bounding volume.

`fn compute_b_cost(&mut self, _: &B) -> Option<(N, Self::UserData)>`

Computes the cost of an object, and the result to be returned if it is the best one.

Implementors

impl<'a, N, B, BV> BVTCostFn<N, B, BV> for RayIntersectionCostFn<'a, N> where N: Real, B: RayCast<N>, BV: RayCast<N>, type UserData = RayIntersection<N>;
