Pixel Noir is a real-time demo that my colleague Thomas Weber and I have programmed during a lab course at the Vienna University of Technology in winter 2010. Our goal was to create a short scene that showcases cinematic real-time graphical effects as provided by our own render-engine based on modern OpenGL.Here are a few technical facts and features of our demo project: Variance Shadow Mapping Post-Process Depth of Field Particle-effects for dusty air-particles Gamma-correct handling of textures and image output Tone mapping and cinematic color curves Barrel distortion Adhoc evaluation of bezier splines for animated objects Using Loose Octrees for View Frustum Culling. COLLADA based content pipeline, including import of geometry, animations, common materials with textures and additional 3D Studio Max specific extra profile data. Awesome OpenGL core profile and extension loader, automatically generated from the OpenGL specification. OpenGL 3.3 core profile
