EBGeometry_AnalyticRayForms.hpp File Reference

Ray forms (see RayForm) for the analytic shapes that have a closed-form crossing: PlaneSDF, SphereSDF, BoxSDF, CylinderSDF, InfiniteCylinderSDF and CapsuleSDF. With this header included, firstHit() and intersects() on these shapes are exact instead of marched, and so are compositions of them (see EBGeometry_CSGRayForms.hpp): each is convex, so the ray is inside it over one span, which spans() gives.

struct	EBGeometry::RayForm< InfiniteCylinderSDF< T > >
	InfiniteCylinderSDF's ray form: the roots of a quadratic, in the plane across its axis. Exact, and callable on a device. More...
struct	EBGeometry::RayForm< CapsuleSDF< T > >
	CapsuleSDF's ray form: the span of the cylinder between its centers and of the two balls at its ends, which, the capsule being convex, is one interval. Exact, and callable on a device. More...

Detailed Description

Ray forms (see RayForm) for the analytic shapes that have a closed-form crossing: PlaneSDF, SphereSDF, BoxSDF, CylinderSDF, InfiniteCylinderSDF and CapsuleSDF. With this header included, firstHit() and intersects() on these shapes are exact instead of marched, and so are compositions of them (see EBGeometry_CSGRayForms.hpp): each is convex, so the ray is inside it over one span, which spans() gives.
