Repair of ice statues
19.10., deadline: 9.11.
Story: You are an administrator of an ice statues
museum. You did not care enough for the refrigeration, the temperature grew and
the statues started to melt down: not too much but their edges are now rather
soft. You would like to repair it before anybody notices. It means to work a
bit on the statues in such a way the sharp edges reappeared.
input is a surface geometric model made of triangles, it can contain
holes. Make a program which allows swapping edges in the triangulation
according to the angle of neighbouring triangles
sharing an edge (a choice of the “better” angle from two possibilities). The
program has to allow an easy change of the criterion of edge swapping,
possibility to constrain the swaps on only a subset of the given points.
Input and changed data should be visualized in two windows, visualization
of lighted and surface models, a possibility to
visualize indices of points. Input and output data are in TRI file, input
data will be given and explained by me. If you preferred NOT to write the visuzalization program and concentrate only on
swapping, it is also possible, you can get the visualization program ready
from me. You will get 6 points for the
visualization program, 6 points
for the edge swapping program and other 4 points in the case that your swapping will be more clever
and will contain also “non-local“ criterion, i.e. following and recover of
the sharp edges with considering higher number of triangles.
As you need some extra information for this
project, I want to make a meeting with those who will be solving this problem.
Therefore, you should proclaim your interest as soon as possible, till 22.10 at the latest, in order to make
one meeting only.
