C RAY CASTER

A simple ray caster that tries to draw everything through the CPU even on modern displays by utilizing multithreading.

TODO

Since this program still has a long way to go this is the roadmap for now:

• implement ceiling and ground rendering
• implement sprite rendering
• dynamic lights
• static lights
• cpu only rendering with platform-agnostic compilation

this list will change in the future

Dependencies

Depends on the compilation target. For now the available targets are the following:

• SDL3 => needs SDL3

Build

Without specifying a BACKEND the compilation will select from a list of targets and pick the first working solution:

$ make
$ ./ray_caster

When specified BACKEND will compile for that target directly if the necessary Dependencies are available:

$ BACKEND=sdl3 make
$ ./ray_caster

AI Usage

AI has been used in the development of this project. Precisely AI has been used for the following:

• understanding the math needed for the ray-casting algorithm
• monitoring the performance bottlenecks of the application
• Write the Makefile needed to compile the project
