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.
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.
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.
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.
double ON_TrianglePlane::Elevation  (  const class ON_3dPoint *  point  )  const 
Parameters: point  [in] Returns: Signed elevation of point above/below triangle's plane.
double ON_TrianglePlane::Elevation  (  const class ON_3fPoint *  point  )  const 
Parameters: point  [in] Returns: Signed elevation of point above/below triangle's plane.
double ON_TrianglePlane::Elevation  (  const double  point[3]  )  const

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.
