PBR Demo

Info:

A simple app to test out a Pbr shader that uses the metallic model and the Cook-Torrence BRDF (whatever that means... I basically just copied the code from https://learnopengl.com/PBR/Theory)

Controls:

Right click & WASD to move camera

Buttons in bottom left swap material & model. Buttons in bottom right swap environment.

Couple of hidden features too for the adventurous to discover.
