The program based on SIGGRAPH 05 paper, Mesh Saliency (Lee et al, 2005), implemented by OpenGL 4 and Assimp. Using mean curvative (Taubin, 1995) to improve the performance of Surface simplification (Garland et al, 1997). Some codes modified by "Anton's OpenGL 4 Tutorials". And you can use the follow code to compile the program:

make -f Makefile
./mesh_saliency
