An absolutely phenomenal book I'd recommend on writing your own computer graphics from scratch is 'Tricks of the 3D Game Programming Gurus' [1] by Andre LaMothe. It was published in 2003, but as it's about how technology works and not using whatever the latest graphics API is - it's timeless. It goes through everything in immense, yet still very accessible, detail. You start from nothing and at the end have a fully lit, shadowed, spatially partitioned, animated, textured, 3D game - using a software renderer that you write from scratch.
