◆ Create() [1/4]

bool ON_TrianglePlane::Create	(	const double	A[3],
		const double	B[3],
		const double	C[3],
		bool	bSinglePrecisionPoints
	)

Description: Create a triangle plane equation from three points. Parameters: A - [in] B - [in] C - [in] corners of the triangle. bSinglePrecisionPoints - [in] True if the point locations were created from single precision information (floats). False if the point locations were created from double precision information. Returns: True if the three points are not coplanar and a plane equation was created. False if a plane equation could not be created. When false is returned, a, b, and c are set to ON_UNSET_VALUE and d and tol are set to 0.

◆ Create() [2/4]

bool ON_TrianglePlane::Create	(	const float	A[3],
		const float	B[3],
		const float	C[3]
	)

Description: Create a triangle plane equation from three points. Parameters: A - [in] B - [in] C - [in] corners of the triangle. Returns: True if the three points are not coplanar and a plane equation was created. False if a plane equation could not be created. When false is returned, a, b, and c are set to ON_UNSET_VALUE and d and tol are set to 0.

◆ Create() [3/4]

bool ON_TrianglePlane::Create	(	const ON_3dPoint *	A,
		const ON_3dPoint *	B,
		const ON_3dPoint *	C,
		bool	bSinglePrecisionPoints
	)

Description: Create a triangle plane equation from three points. Parameters: A - [in] B - [in] C - [in] corners of the triangle. bSinglePrecisionPoints - [in] True if the point locations were created from single precision information (floats). False if the point locations were created from double precision information. Returns: True if the three points are not coplanar and a plane equation was created. False if a plane equation could not be created. When false is returned, a, b, and c are set to ON_UNSET_VALUE and d and tol are set to 0.

◆ Create() [4/4]

bool ON_TrianglePlane::Create	(	const ON_3fPoint *	A,
		const ON_3fPoint *	B,
		const ON_3fPoint *	C
	)

Description: Create a triangle plane equation from three points. Parameters: A - [in] B - [in] C - [in] corners of the triangle. Returns: True if the three points are not coplanar and a plane equation was created. False if a plane equation could not be created. When false is returned, a, b, and c are set to ON_UNSET_VALUE and d and tol are set to 0.

◆ Elevation() [1/4]

double ON_TrianglePlane::Elevation ( const class ON_3dPoint * point ) const

Parameters: point - [in] Returns: Signed elevation of point above/below triangle's plane.

◆ Elevation() [2/4]

double ON_TrianglePlane::Elevation ( const class ON_3fPoint * point ) const

Parameters: point - [in] Returns: Signed elevation of point above/below triangle's plane.

◆ Elevation() [3/4]

double ON_TrianglePlane::Elevation ( const double point[3] ) const

◆ Elevation() [4/4]

double ON_TrianglePlane::Elevation ( const float point[3] ) const

◆ Normalize()

bool ON_TrianglePlane::Normalize ( )

Description: Scale a,b,c,d and tol by the same factor so that 1 = a^2 + b^2 + c^2. Returns: True if the scaling was successful. False if (a,b,c) is the zero vector or cannot be unitized. When false is returned, the values of a, b, c, d and tol are set to 0.0.
