my "main" function works normally and gives me the sphere visualization.But,
when I pick on the sphere, directly, the error message is displayed. So I
deduced that the error comes from the last added code, in which I added
triangleFilter and subdivisionFilter. my program code is long, but i have to
put it as it is, in order that you can compile it and see the message error:
