WEM Overview

WEM - General Information

The approach of the WEM (Winged-Edge Mesh) library is to unify the generation, the processing and the rendering of surface representations. By writing WEM modules for MeVisLab, developers can focus on certain tasks like the smoothing of a surface, the reduction of faces of a surface mesh, or special rendering of data. Several WEM-related modules can be connected in order to form mesh-processing pipelines. This helps solving certain problems arising in the processing and the visualization of medical data.

This library provides a basis for dealing with common tasks: an isosurface can be generated at a certain threshold out of medical images, and the resulting surface can be reduced in its amount of primitives or can be smoothed by using different algorithms. For rendering, the surface can be colored in order to reflect certain additional information or according to a flexible coloring scheme out of the image data itself. Finally, all the generated and modified surfaces can be saved and loaded with a variety of different file formats that are compliant with standard 3D applications.
