Detailed Description

Header to expose Shewchuk's exact predicate functions. This is a private interface to third party code. Most code should instead use ExactPredicates.h, the Unreal Engine-style interface

Function Documentation

◆ exactinit()

void ShewchukExactPredicates::exactinit ( )

must be called before running any exact predicate function. called by module startup.

		const double *	pb,
		const double *	dir
	)

◆ facing3d()

double ShewchukExactPredicates::facing3d	(	const double *	pa,
		const double *	pb,
		const double *	pc,
		const double *	dir
	)
