◆ 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.
