A (very) simple ray caster using Go and SDL
Just a fun project to see how hard it would be to create a Wolfenstein3D like ray caster. I have not put much effort into optimization for either CPU or memory as I'm favoring readability over speed.
I have also not added texture maps or complex lighting. I may add these at some point in the future, but I really just wanted to create a basic space I could explore.
This is in Go (since that is what I use most of the time at work) with SDL for drawing. In order to build this you first need to
brew install sdl2{,_image,_mixer,_ttf,_gfx} pkg-config
and then you should be able to just build and run the app.
I'm still playing around with some of the color shading and I may go through and do some small optimizations, but for the most part I'm done with the main work.
