The UnityMol development documentation was generated with DoxyGen. It was initiated by Axel Viala. It can be accessed directly from this server through this link.
UnityMol is CiteWare, so please mention our PLoS One and SweetUnityMol articles when you use UnityMol in your projects. We would also welcome your contributions to integrate your developments and improvements in the official UnityMol version for everybody. UnityMol development would not have been possible without the many resources available through the Unity3D forums, and it is thus natural to "give back" the outcome of this work.
Concerning source code availability, the everyday development of UnityMol does not take place on a public repository but in our lab's internal gitlab environment. We do release source code with every major UnityMol version, typically when the related paper gets accepted. If you need source code access in between these releases, please contact us to find an appropriate solution.
