CreateCylinderLocalizer()

bool ON_Localizer::CreateCylinderLocalizer	(	ON_3dPoint	P,
		ON_3dVector	D,
		double	r0,
		double	r1
	)

Parameters

P	[in] cylinder axis point
D	[in] cylinder axis direction
r0	[in]
r1	[in] r0 and r1 are radii that control where the localizer is nonzero. Both r0 and r1 must be postive and the cannot be equal. If 0 < r0 < r1, then the localizer is zero for points inside the cylinder of radius r0 and one for points outside the cylinder of radius r1. If 0 < r1 < r0, then the localizer is one for points inside the cylinder of radius r1 and zero for points outside the cylinder of radius r0.

Returns

True if the input is value and the localizer is initialized.

CreatePlaneLocalizer()

bool ON_Localizer::CreatePlaneLocalizer	(	ON_3dPoint	P,
		ON_3dVector	N,
		double	h0,
		double	h1
	)

Parameters

P	[in] point on plane
N	[in] normal to plane
h0	[in]
h1	[in] h0 and h1 are signed distances that control where the localizer is nonzero.

Returns

True if the input is value and the localizer is initialized.

CreateSphereLocalizer()

bool ON_Localizer::CreateSphereLocalizer	(	ON_3dPoint	P,
		double	r0,
		double	r1
	)

Parameters

P	[in] center of sphere
r0	[in]
r1	[in] r0 and r1 are radii that control where the localizer is nonzero. Both r0 and r1 must be postive and the cannot be equal. If 0 < r0 < r1, then the localizer is zero for points inside the cylinder of radius r0 and one for points outside the cylinder of radius r1. If 0 < r1 < r0, then the localizer is one for points inside the cylinder of radius r1 and zero for points outside the cylinder of radius r0.

Returns

True if the input is value and the localizer is initialized.
