Bishop3D is an interactive 3D modeler and animation tool projected and built to interface with the popular freeware raytracer POV-Ray™ (Persistence of Vision Raytracer™) on MS-Windows platform.
POV-Ray creates three-dimensional photo-realistic images, taking as input a text file with the scene described in a script language known as POV-Ray Scene Description Language (SDL) - if you are unfamiliar with POV-Ray, check these example images, I'll wait you catch your breath.
With Bishop3D you can model the scenes interactively using a graphical interface and it will automatically generate the correspondent POV-Ray SDL script.
Bishop3D communicates with POV-Ray via POV-Ray's extension interface, providing a seamless integration between the modeler and the renderer. You can start render jobs and see the results without ever leaving Bishop3D.
If you are looking for a polygonal mesh sculpting software I would suggest you take a look at the freeware Wings3D; You can create the mesh models there and latter import them into Bishop3D for texturing, lighting and rendering.
(sure there are many others, I just don't want to feel bad for letting you leave empty handed ;-) ).
If your focus is character animation, then I'm afraid you need to go with the big 3D industry titles (3ds Max, Maya, etc.) or find your way through the infamous learning curve of Blender.
