Simple software rasterizer from scratch, no dependencies (see below). Whole stuff including math & string classes + .obj parser + image loader + simple scene editor and of course rasterizer with perspective correct texture mapping itself :) is ~3k loc (was written ad-hoc for this small project), about similar amount of code to get a triangle on screen in Vulkan :) This is WIP, no SIMD on purpose as hopefully in future I'll port it to a very tiny MCU
All "interesting" stuff in main.cpp
None, seriously :) Actual rasterizer does not depend on anything, but I use ImGui for my "editor/debugging framework" (added NOT as submodules for simplicity), so here you are. Probably need to add some NO_EDITOR define to strip all this out and save output to .ppm files
Linux:
cd soft_rast
cmake -S . -B ./build
cd ./build
make -j$(nproc)
Windows:
never tried, should be simple enough
Some test models are converted from nice pack at elbolilloduro.itch.io, psionicgames.itch.io, moon is from craftpix.net
