Four

An (incomplete) 4d rendering library written in C++
Example: An orthographically projected pentachoron (5-cell) rotating about the yw-plane (the code for this can be seen in pchoron.cpp):

Example: A 4d-3d perspectively projected and 3d-2d orthographically projected tesseract rotating about the zw-plane (the code for this can be seen in hypercube.cpp):

What still needs to be done

• Write unit tests
• Solid and wireframe mode interoperability
• hide everything GLM related
• write build instructions for Windows
• Camera Controls
• File/model loading
• Clarify private and public functions
• Premade geometries (hypercubes and pentachorons)

How to use

When compiling, include the C++ files in the include/ directory and use the compiler flags for glfw3 and glew.
This library uses C++11 features
Build examples for hypercube.cpp:
MacOS (tested on OS X 10.15.7):
      g++ hypercube.cpp include/*.cpp -o hypercube -lSDL2 -lglew -framework OpenGL -std=c++11
Linux (tested on Fedora 33):
      g++ hypercube.cpp include/*.cpp -o hypercube -lGL -lGLEW -lSDL2 -std=c++11

More detailed instructions are coming later, but for now, see hypercube.cpp, pchoron.cpp, and test.cpp for examples.
