Based on the idea
of Professor

DemoSlide3
Requirements
Use
libQGLViewer
as the GUI
Load a mesh (*.off) by CGAL
Use CGAL
::
Polyhedron_3 as the data structure for the mesh
Display the mesh
Select & unselect one vertex of the mesh
Compute geodesic distance from the vertex to all other vertices
& draw
the mesh with vertex color specified by the distances.
Select two vertices, draw a geodesic between them
Visualize other graph algorithms, such as BFS [advance]
Note: may refer to
The
Boost Graph
Library
for graph structures and
algorithms. But the library is hard to use
for beginners.Slide4
