Oh wow, POV-Ray was finally open-sourced. I remember playing around with it maybe 15 years ago now. The Internet Ray Tracing Competition[1] was still a going concern, and one of the rules was that post-processing was disallowed. So people got motion blur by recompiling the program to average several frames together, which didn't count as post-processing since it was still a ray-tracer that did it.

Wasn't the source "always" available but just under a custom non-FOSS compatible license? I used to use POV-Ray quite a bit and participated in the IRTC a few times as well. Even 15 years ago the reason for keeping the legacy license was IIRC mostly that it would have been a huge task to get in touch with all the contributors or alternatively to rewrite all the parts that could not have been relicensed.


Yeah the source was available for as long as I used it (hence people being able to hack on it for the motion blur), but always under the no-redistribution license. I wasn't yet very familiar with FOSS but I remember understanding that the source being available was a big deal, and the no-redistribution clause was also a big deal.
