OpenGL-cpp
Tried OpenGL in 2018 in Visual studio. Current main.cpp is capable of drawing a triangle with the help of vertex and fragment shaders. 180 lines of code just to draw a triangle was fun and time consuming. To be fair, most of it was setting up GLEW and GLFW.
Libraries used: GLEW 2.1 32 bit GLFW 3.3.2
My opinion on GLSL(shading language)? Complex and not so fun.
