Reimplementing the wheel

The goal of this project is nothing, but to have fun and to understand how things work by implementing them from scratch. Code is written in C++ (C++17) and is not intended to be used in production.

The structure of the project

The top-level folders contain stand alone libraries. Each library has a set of unit tests and (sometimes) benchmarks. The third_party folder contains third party libraries that are used in the project. The sandbox folder contains simple applications that use the libraries.

Building the project

The project uses Bazel as a build system.

For instance, to build a math library use the following command:

bazel build //math/...

To run tests for the math library use the following command:

bazel test //math/...

Currently implemented:

• software renderer and math libraries. To run the software renderer demo application use the following command:

bazel run //sandbox/sw_renderer -c opt

Note the -c opt flag, which is used to run the application in release mode to get better performance.

Third party libraries

• SDL2 - Simple DirectMedia Layer is a cross-platform development library designed to provide low level access to audio, keyboard, mouse, joystick, and graphics hardware via OpenGL and Direct3D
• fmtlib - A modern formatting library
• googletest - Google Testing and Mocking Framework
• benchmark - A microbenchmark support library
• imgui - Bloat-free Immediate Mode Graphical User interface for C++ with minimal dependencies
• implot - Advanced 2D Plotting for Dear ImGui
• CLI11 - CLI11 is a command line parser for C++11 and beyond that provides a rich feature set with a simple and intuitive interface
