computer graphics & visualization Image Synthesis – WS 07/08 Dr. Jens Krüger – Computer Graphics and Visualization Group Outline of course Interactive image synthesis Interactive rendering (i.e. local illumination) DirectX/OpenGL – concepts and (syntax) Textures and mapping techniques Shadows, reflections Effects (fur, volumes, particle systems …) Programmable graphics hardware Scenengraph (high-level) APIs Physics based rendering Radiometric quantities, radiance-equation Radiosity Photon mapping BRDF (reflection properties of real material) Other Topics Image based rendering REYES High dynamic range imaging Point based rendering Image Compression, e.g. JPEG, MPEG, PNG, GIF

computer graphics & visualization Image Synthesis – WS 07/08 Dr. Jens Krüger – Computer Graphics and Visualization Group Interactivity vs. Photorealism Realistic images („as a photo“) Only by physical simulation of Light emission and light transport Interaction between light and matter (reflection, scattering) Image synthesis (recording and perception) Very expensive (i.e. not interactive) Interactive graphics (not very realistic in general) Hardware support for „trivial“ functions Tricky approximations Games, virtual environments, training simulators Tend to become increasingly realistic
