This could be the most high-end free software ever: it's the very tool used to render the images you see in Pixar's movies. That's because RenderMan was developed by Pixar in-house for that purpose, but became free for non-commercial use. It's not going to do you much good without other software such as Autodesk's Maya for creating 3D models. But budding artists and filmmakers will want to take note. You'll need a 64-bit system to run it.
The right to study and modify a computer program entails that source code—the preferred format for making changes—be made available to users of that program. While this is often called 'access to source code' or 'public availability', the Free Software Foundation recommends against thinking in those terms, because it might give the impression that users have an obligation (as opposed to a right) to give non-users a copy of the program.
The FSF list is not prescriptive: free licenses can exist that the FSF has not heard about, or considered important enough to write about. So it's possible for a license to be free and not in the FSF list. The OSI list only lists licenses that have been submitted, considered and approved. All open-source licenses must meet the Open Source Definition in order to be officially recognized as open source software. Free software on the other hand is a more informal classification that does not rely on official recognition. Nevertheless, software licensed under licenses that do not meet the Free Software Definition cannot rightly be considered free software.
Most freelancers put calls-to-action on their sites asking prospects to set up a consultation.
