Detailed Description

Generated from:  MR::InSphereTester<float>
Aliases:  InSphereTesterf

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

Member Function Documentation

__call__()

InSphereResult mrmeshpy.InSphereTester_float.__call__	(		self,
		Vector3f	d )

returns the position of the point d relative to the sphere (never NoSphere);
shall be called only after reset() returned true

operator() [1/2]

reset()

bool mrmeshpy.InSphereTester_float.reset	(		self,
		Vector3f	va,
		Vector3f	vb,
		Vector3f	vc,
		float	sqRadius )

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
