MR.InSphereTester_Float Class Reference

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<float>.

Detailed Description

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<float>. This is the non-const half of the class.

Member Function Documentation

assign()

unsafe MR.InSphereTester_Float MR.InSphereTester_Float.assign ( MR.Const_InSphereTester_Float _other )

inline

Generated from method MR::InSphereTester<float>::operator=.

flip()

unsafe void MR.InSphereTester_Float.flip ( )

inline

swaps the points b and c, which selects the mirror sphere with the center on the other side of plane abc, and gives exactly the state of reset( a, c, b, rSq ) without recomputing anything: only the normal w changes there, and W, M, E are symmetric in b and c; shall be called only after reset() returned true Generated from method MR::InSphereTester<float>flip.

reset()

unsafe bool MR.InSphereTester_Float.reset ( in MR.Vector3f va, in MR.Vector3f vb, in MR.Vector3f vc, float sqRadius )

inline

prepares the tester for the sphere of radius sqrt(rSq) passing via points a, b, c, with the center located on the positive side of plane abc (in the half-space pointed at by cross( b - a, c - a ) from the plane); returns false if no such sphere exists: the points are collinear or coincident, or rSq is less than the squared circumradius of triangle abc Generated from method MR::InSphereTester<float>reset.
