3D software rasterizer using C/ C++

REX

Rex is a side project I'm working on now for the purpose of learning more about graphics programming and rendering. Currently it's just a 3D software rasterizer.

Supported platforms

• Windows
• Linux
• Web-Assembly (https://waleedyaser.github.io/rex-wasm/)

Build and install

• Download and install CMake (at least version 3.12): https://cmake.org/download/

• On Linux make sure to install these dependencies:

   sudo apt install -y libxcb1-dev libxcb-util-dev libxcb-keysyms1-dev libxcb-image0-dev
  

• Configure and build the project by executing the following commands:

   cmake -B build -DCMAKE_BUILD_TYPE=Release
   cmake --build build --config Release -j
  

• The output (rex-viewer.exe) will be in build/bin/Release/ directory.

• You can install binaries to any folder by executing the following command:

   cmake --install build --prefix INSTALL_PATH
  

  replace INSTALL_PATH with the path you want.

• You can package the binaries to a zip file using the following steps:

   cd build
   cpack -G ZIP
  

  You should have rex-VERSION-win64.zip file in the build directory.

Setup emscripten for windows (TODO)

emsdk activate mingw-4.6.2-32bit

cmake -G "MinGW Makefiles" -B build-wasm -DCMAKE_TOOLCHAIN_FILE=D:/code/emsdk/upstream/emscripten/cmake/Modules/Platform/Emscripten.cmake
