This is the python implementation of the OpenGL tutorial on www.learnopengl.com
Vispy stable release dont support #330 version of GLSL, so we are using older versions
where out and in are replaced by varying keywords, and attributes are used instead of layout
You have to setup vispy for your project or use the requirements.txt
Vispy do not support structs in fragment shader which means something like `self.program['material.ambient'] is not gonna work.
Will be continuing the tutorials on pyopengl now onwards.
