WebA "cleaner" way to do define the 3D point is to use inheritance. // Struct inherits a Point2D object struct Point3D_inherit : public Point2D { double z_; }; This new struct has the exact same physical structure as the previous two 3D point structs and is still compatible with C: http://www.compsci.hunter.cuny.edu/~sweiss/course_materials/csci235/lecture_notes/chapter_08.pdf

WebAnother approach would be a function (not class member method) double distanceBetween (const threeD& ptA, const threeD& ptB), which could be used anywhere.It may be more reasonable for general algorithms as well. In any case, this is just a suggestion. Your approach is perfectly reasonable. Reply to this topic Be a part of the DaniWeb community WebInheritance is an "is-a" relationship. A 3D point is not a 2D point, even though there is a lot of overlap, but that third dimension makes them completely different things. You can't find the distance between a 3D point and a 2D point, unless you convert the 2D point to a line, but then if you have a 2D point, you have to know that it is actually a 2D point and not a …
