The following tutorials assume you have some C++ knowledge including a basic understanding of virtual functions. If you have some Opticks plug-in development experience, try either Getting Started, Overviews and HOWTOs or the Class documentation.
The Opticks SDK contains the tutorial plug-ins that are referenced in this Tutorial. You can download the Opticks SDK from the Downloads page of the https://opticks.ballforge.net/ website.
Start with the first tutorial and work your way through as each successive tutorial builds on the previous one.
