Intro to computer Graphics/shaders

[rico001]

Found a free online book. It is also available from a publisher for money.

Computer Graphics from Scratch by Gabriel Gambetta "....demystifies the algorithms used in modern graphics software with basic programming and high school math." https://www.gabrielgambetta.com/compute ... m-scratch/

Also the flight gear canvas supposedly can be used to draw 2D things. See documentation for that.

I'd recommend 'Real Time Rendering' as great a introduction, I have the third edition but 4th edition is out now : for FlightGear a second-hand copy of the older editions will do you fine
