calcAABB()

math::AABB3D ph::BruteForceIntersector::calcAABB ( ) const

overridevirtual

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

Implements ph::Intersector.

isIntersecting()

bool ph::BruteForceIntersector::isIntersecting ( const Ray & ray, HitProbe & probe ) const

overridevirtual

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.

isOccluding()

bool ph::BruteForceIntersector::isOccluding ( const Ray & ray ) const

overridevirtual

Determines whether this object blocks the ray.

If greater performance is desired, you can override the default implementation which simply calls isIntersecting(const Ray&, HitProbe&) const to do the job. The test generally considers the underlying shape as hollow (for closed shape), e.g., a sphere is not occluding a line segment inside the sphere.

This method does not provide any means to retrieve HitDetail. Focusing on testing occlusion can improve performance for some cases.

Reimplemented from ph::Intersectable.

update()

void ph::BruteForceIntersector::update ( TSpanView< const Intersectable * > intersectables )

overridevirtual

Implements ph::Intersector.
