Question

I am beginner at modelling and etc., but I have a school task which I explained in the title and I searched for tutorials and I found many at Unity's page, but I didn't find anything about lighting in fragment shader. Any lead how to start?

Answer 1

I would recommend checking out https://github.com/bkaradzic/bgfx The samples are a great resource to get started.

If you feel you need to know more about computer graphics, how the pipeline works and some of the math. I would recommend taking this free course https://www.udacity.com/course/cs291
