Sculptris is another great free 3-D modeling software. Unlike Blender, Sculptris is a lot easier to use. You can quickly make some nice 3-D shapes and 3-D faces with Sculptris. In fact, even kids can create 3-D models easily with Sculptris.
Apart from that, Sculptris does not consumes lot of system resources. The interface is quite intuitive, and is organized in the same manner as any image editing software. All the tools are organized nicely, and you can pick any of them to start your 3-D modeling.
