is a more professional and visually and technically a way of presentation.
Currently there are programs to present on the website and not only the animation of products describing how things work. And I'm not talking about big players (expensive) like Unity3D or UnreelEngine only partially free like blend4web.
examples can be found here: https://www.blend4web.com/en/demo/
and here is my sample: http://www.lchyl.avx.pl/reqnet/
you can rotate, zoom in to stop - change colors and even view in VR;)
