You can also use Blender, which is opensource (with whatever that means in cost ;-). Also you can Use Open3D or other stuff. Check out
http://www.freshmeat.net/ for other free/opensource tools you may want to use. They're been made to be used for such cases, so why don't use them since they're free? :-)
It's like the linux case: linux is better, but people prefer windows because they pay for them... (ok, ok, i know that the microsoft marketing blurb helps a bit, but i'm just pretending that i don't know it ;-).
