❓ About

This is a project where I learn how a raytracer works by building one. To accomplish this, I will be following along a few books, in particular the Ray Tracing in One Weekend series.

The output of this programme is a PPM file that contains the rendered image.

🛠️ Building and Running the Code

To run this code, you'll need to build it as it uses CMake. To build it, go to the root directory in the terminal and run the commands:

cmake -B build
cmake --build build

The cmake --build build command should be run whenever a change is made to the CMakeLists.txt file in the build directory.

To run the code, you run the command:

Windows: build\Debug\Raytracer.exe > image.ppm
Mac and Linux: build/Raytracer > image.ppm

Optimised Builds

This build option is to render faster.

For Windows, run this command to optimised build:

cmake --build build --config release

And to run the build:

build\Release\Raytracer.exe > image.ppm

For Mac or Linux, run these commands to obptimise build for the fastest results:

cmake -B build/Release -DCMAKE_BUILD_TYPE=Release
cmake --build build/Release

And to run the build:

build/Release/Raytracer > image.ppm

You'll need an image viewer to view the PPM file. I used feh.
