ON_3dPointListRef::ON_3dPointListRef | ( | const class ON_Mesh * | mesh | ) |
Description: Construct a point list that references the mesh vertex list. Remarks: If the mesh has double precision vertices, then the point list will refer to them; otherwise, the point list will refer to the single precision vertices.
ON_3dPointListRef::ON_3dPointListRef | ( | const class ON_SimpleArray< ON_3dPoint > & | point_array | ) |
Description: Construct a point list that references the points in a simple array of ON_3dPoint objects.
ON_3dPointListRef::ON_3dPointListRef | ( | const class ON_SimpleArray< ON_3fPoint > & | point_array | ) |
Description: Construct a point list that references the points in a simple array of ON_3fPoint objects.
bool ON_3dPointListRef::DoublePrecision | ( | ) | const |
Returns: true if the points are double precision

unsigned int ON_3dPointListRef::GetMeshFacePoints | ( | const class ON_MeshFace * | mesh_face, |
ON_3dPoint | face_points[4] | ||
) | const |
Returns: Number of points copied to face_points[] array.
unsigned int ON_3dPointListRef::GetMeshNgonPoints | ( | const class ON_MeshNgon * | mesh_ngon, |
ON_SimpleArray< ON_3dPoint > & | ngon_points | ||

Description: Copy point location into buffer and return it as an ON_3dPoint. Parameters: point_index - [in] buffer - [out] If point_index is a valid index, the point coordinates are copied to buffer[]; otherwise the buffer coordinates are set to ON_UNSET_VALUE. You must insure buffer is not null, has proper alignment for storing doubles, and is large enough to store three doubles. Returns: A reference to an ON_3dPoint which is a cast of buffer. Remarks: This is the fastest and most efficient way to get a the location of a point into memory you are managing.
