Could also be "Poser", which uses "Daz3D" models... (Gen3 models don't function as they do in Daz3D, but they can be exported, once posed, for rendering and other manipulations.)
They also export, with some-more limits, to... Cinema-4D, Maya, Blender, iClone... and 3DS-Max
There are also various rendering-engines... Some come with certain 3D-manipulators, like Daz3D and Poser, as well as each of the various plugins for actual 3D-Modeling programs.
90% of everything used now, is all prefabricated Daz3D stuff. It just works, it's easy and much is free. Other 3D things usually require some kind of intimate knowledge to use them. Not to mention that other things are difficult to obtain.
Daz3D is the gateway drug to actual 3D-Development... Just like SketchUp-3D is, to actual architecture.
