# Batomorph

This is a simple raytracer, written for POSIX systems in C23 with zero
runtime dependencies (outside of the standard library).  To build with
CMake:

```sh
cmake -B build
cmake --build build
```

You may want to adjust the `NTHREADS` definition in `src/render.c` to
match your system for best performance.

When ran, the demo programs (`build/demo` and `build/rand`) will write
the rendered image in sRGB
[Farbfeld](https://tools.suckless.org/farbfeld/) to standard out.  For
example:

```sh
build/demo > out.ff           # Produce Farbfeld file
build/demo | ff2png > out.png # Produce PNG file
build/demo | feh              # View directly
```

(Note that `ff2png` and `feh` are third-party programs)
