Welcome to the NUKE Developer Guide. This is intended for use with the bundled NUKE Developer Kit (or NDK), which allows writing and compilation of C++ plug-ins (essentially shared libraries) for use inside of NUKE. The Developer Guide is designed as a getting started walkthrough for many common areas of plug-in writing, from constructing your first simple PixelIop, through to the esoterics of particle behaviours, 3D ops and more. It is not intended to be a replacement for the class reference documentation provided as part of the NDK, but rather as a complementary document. It is also not intended as an introduction to C++, and will throughout assume a good working knowledge of the language. If you are coming to the NDK without a working knowledge of the language, there are a wide variety of getting started texts available, including Scott Meyers’ “Effective C++” and “Effective STL” for good practice guidelines.
Note
This guide, and the NDK as a whole, is not intended for plug-in writers looking to utilise the OpenFX (OFX) API. The OFX API is designed for commercial plug-in writers looking to write and compile a plug-in once and have them run across a number of hosts, and host versions. The NDK, on the other hand, offers a far greater degree of access to underlying NUKE functionality, but does require recompilation of plug-ins far more frequently due to API changes. The OFX API is documented on the OFX SourceForge site.
Note
Throughout this guide, we’ll refer to NUKE. NUKE can be taken to mean either NUKE or NUKEX, since NUKEX is essentially the same package with options unlocked by different types of license.
To develop NUKE plug-ins you will need:
Using this guide effectively entirely depends on your current NDK knowledge level. Those with exposure to the API already should just be able to dip in and out of the sections covering their intended plug-in’s operating area. For those without previous exposure, the sections are laid out to follow the suggested reading order. Major plug-in areas also have exercises associated with them for those looking for a more ‘cookbook’ approach to aid inhouse training. This guide does not replace the class reference documentation which appears alongside it. By referring to class reference and header files and experimenting with the examples provided, you should be able to gain an indepth knowledge of the areas introduced in this document.
All users should set up their compiler as per Appendix A: Setting up Projects & Compilers if they haven’t done so already, and follow along with the various examples as they are introduced.
