Detailed Description

template<std::size_t N, typename Index>
class ph::TWideBvhIntersector< N, Index >

Wide BVH acceleration structure supporting arbitrary branch factor.

Template Parameters

N	Branch factor of the BVH.
Index	Type for buffer offsets. Types that can store a larger integer supports more intersectables.

Member Function Documentation

calcAABB()

template<std::size_t N, typename Index >

auto ph::TWideBvhIntersector< N, Index >::calcAABB ( ) const

inlineoverridevirtual

Calculates Axis-Aligned Bounding Box (AABB) of itself.

Implements ph::Intersector.

isIntersecting()

template<std::size_t N, typename Index >

bool ph::TWideBvhIntersector< N, Index >::isIntersecting ( const Ray & ray, HitProbe & probe ) const

inlineoverridevirtual

Determine whether a given ray hits the object.

Checks whether the specified ray intersects this intersectable. If there is an intersection, true is returned and a brief hit report is stored inside the probe. If there is no intersection, false is returned and the state of the probe is undefined. ray and probe can be used for obtaining hit detail if an intersection is found.

Note

Generates hit event (with ray and probe).

Implements ph::Intersector.

rebuildWithIntersectables()

template<std::size_t N, typename Index >

void ph::TWideBvhIntersector< N, Index >::rebuildWithIntersectables ( TSpanView< const Intersectable * > intersectables )

inline

update()

template<std::size_t N, typename Index >

void ph::TWideBvhIntersector< N, Index >::update ( TSpanView< const Intersectable * > intersectables )

inlineoverridevirtual

Implements ph::Intersector.
