Exercises

Python usage in the exercises

As discussed we happily allow exercises done in python. Yet we do not have the resources to change our exercises at this moment. Also a quick poll showed only few interested students. If you have problems with python you can write the mailing list as well and hopefully we find an answer.

There are two resources): 1) undefinedSmall introductory sheet 2) Small program to display meshes

Starting the lecture

Please inscribe yourself to the mailinglist at https://lists.iai.uni-bonn.de/mailman/listinfo.cgi/vl-atcg1.

In this lecture you will have the chance to learn many interesting theoretical as well as practical topics. In any case you have a problem understanding, please always feel free to write to the mailing list. This should be a place where you students can talk freely about the lecture, so please do not hesitate to ask and reply! Of course the tutors are on the mailing list as well and will reply as well.

The book "Polygon Mesh Processing" mentioned bellow is available for reading also at our institut - though it may be more interesting for later topics. If you are curious just ask.

Good start !

Description

Digital geometric models

Digital geometric models find nowadays numerous applications ranging from industrial CAD and terrain or scientific visualization to games and movie productions.

This lecture covers all aspects of DGM from their aquisiton and representation to editing and processing. In detail it discusses the following topics:

  • Methods for the generation of polygonal meshes (laser scanning, registration and integration of single mesh parts, etc.)
  • Representation: point based representations, efficient mesh data structures
  • Processing: reconstruction techniques, mesh compression, optimization of polygonal meshes (fairing and remeshing), mesh decimation and refinement, hierarchical representations.

Rendering

This lecture discusses advanced rendering techniques that aim at highly realistic images. Particular emphasis lies on high quality depictions of materials.

In detail the topics of this lecture are:

  • Foundations of radio- and photometry
  • Models for the description of optical material properties and light sources
  • Transport-, volume visualization- and rendering equation
  • Algorithms and techniques for the solution of the volume visualization and rendering equation
  • Algorithms and techniques of image based rendering
