Poser is a 3d modeling program... people make stuff on it and call it their "art." Is it really art to take a 3D model and make it do stuff, then adding lots of other little things in the picture? One might say that this isn't true art, but others say this is simply an art form. I think that the "art" in 3D modeling is yourself and your ablitiy to think of a scene and create it anyway possible, even with poser. Your thoughts and opiouns concerning 3D art?
Well I don't know much of a free equivalent to Poser, don't think there is. But there are several regular 3d-programs that are free and filled with all the features you need.
