Metro: measuring error between surfaces
Sample Images


Metro is a tool recently developed by our group to evaluate the difference between surfaces (eg. a triangulated mesh and its decimated representation).
Metro adopts an approximated approach based on surface sampling and approximated point--surface distance computation.
It returns both numerical results (reported in the tables below) and error magnitude visualization.
Some examples of Metro visual output:
