Computer Graphics deals with hardware, algorithms and datastructures for the synthesis of images or movies from abstract 3D scene, geometry and material descriptions as well as camera/object motion. This lecture introduces the fundamental concepts of computer graphics. In detail the following mayor topics will be discussed:

  • Two and three dimensional object representation
  • Affine and perspective mappings
  • Scene representations/the scene graph
  • Clipping algorithms
  • Raster algorithms
  • Sampling theorem and antialiasing
  • Computing visibility and occlusion
  • Color spaces
  • Optical material properties and shading
  • Textures
  • Global illumination
  • Graphics hardware architectures and rela time rendering
  • Representations of curves and surfaces

Exercises: In the exercises the theoretical concepts of the lecture are examplified in practical programming assignments. Programming is primarily done in C++ using the OpenGL library.
