Subject: Re: [JAVA3D] Transform3D.lookAt function
I find the whole Vector3f vs Point3f thing very painful. It has caused me
numerous problems. I hate the whole tuple hierarchy.
There has only been one case so far where I want to treat a vector different
than a point, when I transform it. It would be far more convenient to have
two methods on Transform3D, transformVector() and transformPoint() rather
than to have two separate classes. This is the only 3d library I have worked
with where point and vector were two separate objects, and I don't much care
for it.
IMO it is OO taken to far.
