OPENGL DEMO
PLATFORM
Windows Desktop
DESCRIPTION
This demo was a way of getting to grips with real time rendering using the OpenGL API. I decided to use the 'core profile', also known as modern OpenGL as it forces the developer to write shaders to render their geometry.
​
The player can move freely in 3D as well as switch between different light types; directional lights, points lights and spot lights. I used the Blinn-Phong lighting model for efficient specular highlights.
​
I also incorporated a model loader to read and draw 3D models from Wavefront .obj files. Lastly, I added help text by drawing generated glyphs onto 2D textures using the 'FreeType' library.
