freestyle_rt_cpp

My first fully working ray tracer running on the CPU.

Features

• Phong lighting model (embient, diffuse, specular light).
• Shadows
• Reflection
• Refraction
• Various shapes (sphere, block, etc.)
• Texture mapping on blocks
• Moving camera

Build (using Make)

• A C++ compiler supporting C++17
• GNU Make

Build and clean commands:

# build the demo executable
make
# remove build artifacts and the executable
make clean
# clean then build
make rebuild

You can run the executable from the project root as follows.

./demo

The output will be written in a .ppm file, as defined in src/main.cpp.
