learningopengl

A C++ OpenGL learning project following learnopengl.com, used as a hands-on way to study graphics programming and C++.

What it does

Renders a 3D scene with two cubes: a textured lit cube and a smaller light source cube. The light position animates over time. Features a free-look camera controllable via mouse and keyboard. I followed along with the chapters while I was reading so the commits contain a history of changes, including displaying a basic triangle, plane, etc.

Chapters covered so far:

• Colors
• Basic lighting (Phong shading — ambient, diffuse, specular)
• Materials (material + light structs in shaders)
• Lighting maps (diffuse + specular texture maps)
• etc.
