Hi there,
I am trying to identify and group a set of triangle based its
corresponding geometry model.
Let's say I have 3 models, a cylinder, a cone and a cube. All these 3
models undergone surface me****ng process and generate a common list of
the triangles.
I need to isolate the triangles into a number of group(in this case it
would be 3).
One of the way I am thinking by using the connectivity relation****p
i.e start from a vertex of any arbitrary triangle and walking through
its neighbors until cover the model.
Repeat the same process until no more triangles left in the list.
I wonder if this is the common way to do it or is there any better way
to solve this kind of problem?
There are a lot of unknown related to the connectivity issue. How do I
really know that I have finish walk through the whole model.
I would appreciate if anyone would provide me any pointer. Thanks in
advance.
jeff
