The goal of this project is to play with rendering on PSP while trying to achieve performance improvement, at least relative to original naive approach Maybe even try to make raytracing realtime idk (5 fps is "realtime" enough imho)
Project is based on code from here which in its turn is forked from this
You need not-so-ancient PSPSDK to compile this
mkdir build && cd build && psp-cmake .. && makeHere is the results of running different commits (psp-g++ (GCC) 15.1.1 20250425)
