Doom Fire (SDL3)

A single-file Doom-fire effect written in C with SDL3. A low-resolution fire buffer is simulated bottom-up with random spread, upscaled 8x, and streamed to the window at ~24 FPS.

Built while learning SDL3 and graphics.

Requirements

• SDL3 development files (this is SDL3, not SDL2)
• gcc and pkgconf

Build & Run

make        # builds ./app
make run    # builds and runs the demo
make clean  # removes the app binary

make run opens a graphical window and requires a display (fails in headless environments).
