3D Polygonal Mesh Surfaces
--------------------------

Contents
^^^^^^^^
* Basic concepts
  
  - Polygonal meshes: vertices, edges and faces. 
  - Topology and geometry
  - STL format for surface files

    
* Shading
  
  - surface shading: diffuse and specular reflection

* Use of Slicer_ to read and render polygonal surfaces

* Use of vtk_ to program reading, creation and visualization of surfaces
