This class is focused on advanced topics in the field of geometry processing. Students will get familiar with recent developments in the area of shape analysis and shape retrieval. Topics among others will be:
Assignment notes
Running Matlab: Unfortunately, there is a bug in the current MATLAB installation in the pool. Before running Matlab it is therefore required to define a certain environment variable. Choose My Computer -> Properties -> Advanced -> Environment Variables -> New (in User Variables). Now define MATLAB_PREFDIR=C:\TEMP\<username>
Installing OMToolbox: In the exercises we will make use of the OmToolbox - an Interface of the OpenMesh Library to Matlab. To install it follow these steps
- download the Toolbox either
Windows Binaries or
Source
- extract OMT archive
- Under Windows in the Pool: Set environment variable VS80COMNTOOLS to the same value as VS90COMNTOOLS, e.g. c:\Program Files (x86)\Microsoft Visual Studio 9.0\Common7\Tools\ (for defining environment variables see Running Matlab). The value of VS90COMNTOOLS can be determined by running the command "set" in the command window
- start Matlab
- add OMT directory and its subdirectories to the Matlab path via File -> Set Path -> Add With Subfolders
