MR_InSphereTester_double

typedef struct MR_InSphereTester_double MR_InSphereTester_double

accelerates testing of many query points against one sphere given by the same three points and radius, pre-computing all the point-independent quantities once; the primary template works for floating-point T with the same case analysis as the precise specialization for int below, so the answers for the query points near the sphere's surface are subject to rounding errors, and OnSphere is returned only on the exact equality in the comparisons; the products inside have degree 16 in coordinates, so to avoid overflows any difference of two given points' coordinates as well as sqrt(rSq) must be below ~100 for T=float and ~1e18 for T=double; the one-call inSphere functions are implemented via this class Generated from class MR::InSphereTester<double>. Supported MR_PassBy modes: MR_PassBy_DefaultConstruct, MR_PassBy_Copy, MR_PassBy_Move (and MR_PassBy_DefaultArgument and MR_PassBy_NoObject if supported by the callee).

enum MR_InSphereResult

the result of inSphere predicates

Enumerator
MR_InSphereResult_NoSphere	the sphere is not defined: the points A, B, C are collinear or coincident, or rSq is less than the squared circumradius of triangle ABC
MR_InSphereResult_Outside	the sphere exists, and the point D is strictly outside
MR_InSphereResult_OnSphere	the sphere exists, and the point D is exactly on it; never returned by the simulation-of-simplicity overload, which resolves such ties into Inside or Outside
MR_InSphereResult_Inside	the sphere exists, and the point D is strictly inside

Function Documentation

MR_inSphere_2()

MRC_API MR_InSphereResult MR_inSphere_2	(	const MR_std_array_MR_PreciseVertCoords_4 *	vs,
		int64_t	rSq )

checks whether the point vs[3] is strictly inside the sphere of radius sqrt(rSq) passing via points vs[0], vs[1], vs[2], with the center located on the positive side of plane vs[0]vs[1]vs[2] (same convention as in the overload above); resolves "vs[3] is exactly on the sphere" ties into Inside or Outside using simulation-of-simplicity: the points are symbolically perturbed (larger perturbations of points with smaller ids; per point the z-coordinate gets larger perturbation than y than x), and the first point whose perturbation moves vs[3] off the sphere decides the answer; known deviations from full simulation-of-simplicity semantics, all answered deterministically for now (covered by sosInSphereDeviations test, to be resolved by ids in the following PRs):

• all three points of the triangle coincide: NoSphere now, while the perturbed triangle is not degenerate and its sphere exists;
• two points of the triangle coincide and the third one is closer than the sphere's diameter: NoSphere now, while the perturbed sphere may exist depending on the perturbation directions;
• rSq is exactly equal to the squared circumradius of a not-degenerate triangle: perturbations change the sphere's existence, affecting both "vs[3] strictly inside" (Inside now) and "vs[3] exactly on the sphere" (Outside now); the remaining degenerate NoSphere answers are exact under full simulation-of-simplicity, because no small perturbation can create the sphere: distinct collinear triangle points, two coincident triangle points with the third one at or beyond the sphere's diameter, rSq below the squared circumradius Generated from function MR::inSphere.
