This is a simple grey-scale renderer that I made to experiment with camera movement and some classical shading methods:

• flat and Gouraud shading: http://page.mi.fu-berlin.de/block/htw-lehre/wise2012_2013/bel_und_rend/skripte/gouraud1971.pdf
• Phong shading: http://www.cs.northwestern.edu/~ago820/cs395/Papers/Phong_1975.pdf

Instructions

Install the following dependencies:

• GLEW (OpenGL loader)
• GLFW (windowing/input)
• GLM (linear algebra)
• assimp (model loading)

Build the program:

make

Run the program:

./_build/rendering

Controls:

• escape: close program
• f: switch between free camera and fixed camera
• mouse: turn camera (free mode) or turn around target (fixed mode)
• up/down: zoom in/out
• left/right: move sideways (free mode only)
• 1: flat shading
• 2: Gouraud shading
• 3: Phong shading
