Outline of course

You should know from CG:

• 2D Raster graphicscolors, transparency, scan-conversion, clipping, ...

• Introduction to 3D graphics3D polygonal models, transformation-pipeline, occlusion, illumination, shading, texture mapping, ...

Image Synthesis – WS 07/08Dr. Jens Krüger – Computer Graphics and Visualization Group

Outline of courseInteractive 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

Interactivity vs. PhotorealismRealistic 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
