A compact raytracer for X Window System written in C
Requires MiniLibX for Linux to work (will install it by itself but you need the dependencies).
MiniLibX dependencies:
-
Ubuntu (or Debian-based):
- libbsd:
sudo apt install libbsd libbsd-dev - X11 headers:
sudo apt install xorg libxext-dev zlib1g-dev
- libbsd:
-
Fedora (or RPM-based):
- libbsd:
sudo dnf install libbsd libbsd-devel - X11 headers:
sudo dnf group install "X Software Development"
- libbsd:
clone with submodules:
git clone --recursive https://github.com/3lswear/minirt_
cd minirt_ && make
Pass a path to a scene file as an argument to the executable:
./miniRT maps/spheres_plane_color_lights.rt
Q /ESCto quit,
SPACE to switch cameras if there are more than one.
Some demo scenes are located in maps folder.
