APPENDIX 5 : DATA DICTIONARY FOR GEOMETRY CLASSES IN SMARTFIREPOINT CLASSPhysical coordinate point class in 3 space dimensions. This class is used to simplify numericalroutines and to tidy up storage in other objects. All of the mesh nodes (cell vertices) are allocatedas an array of pointers to points as follows:Point_Class ** point;point = new Point_Class* [TOTAL_NUMBER_OF_POINTS+1];for ( i=1; i set( 0.5, 1.3, 2.7 );// Getting the displacement vector between point 25 and point 26Vector_Class displace = (*point[26]) - (*point[25]);class Point_Class {public://==> Coordinate values for x, y and z.Float_Type x, y, z;// Methods//==> Point constructor creates a default co-ordinate at (0.0, 0.0, 0.0).Point_Class( Float_Type, Float_Type, Float_Type );//==> Show the coordinates of a point.void show( void );//==> Set the coordinates of a point.void set( Float_Type, Float_Type, Float_Type );//==> Overloaded operator for point assignment (copy).Point_Class& operator=( Point_Class );//==> Overloaded addition of points (adds co-ordinates).Point_Class operator+( Point_Class );Appendix 11.5 Page 145-7 7
