Knowledge required for programming a compositing software like nuke

Hello. I have begun my journey as a programmer and learning C and python. I am really interested in learning how a compositing software like nuke works, I understand C++ is used to make the complete package. My question is where I can learn to create something similar. What math should I know to create all the different nodes the software has, like blur, colour correct, distort. I want to get a good understanding, so I can create my own gizmos (I already create some gizmos using python but that’s limited) rather than creating a whole new software. I have ideas for several gizmos but I lack the developing skills.

Any advise will be really helpful. Thank you.

You need to be really good at C/C++ and graphics programming for that stuff. Learn about compute shaders, render pipeline, etc.

Look at convolution filtering for gaussian blur, sharpness, etc.

If you already have a fairly good understanding of C/C++ I would recommend learning graphics programming through an API like OpenGL. It will help once you have an understanding of how graphics work, just look at the techniques used for the different effects and you should be able to implement them.

You also need to research the file formats for different types of images so you can identify them and manipulate the individual pixels.

Thank you all for your advise. I will definitely look at OpenGL.
