Alan Thank You for your suggestion, however,
the dust puff cloud is a little to wispy and light looking
to look like dirt. Maybe it can be modfied.. Is it possible to modify the parameters to make th particals appear larger and more dense while possessing the proper physical motion??
If it is possible maybe someone could give me some pointers
on the necessary changes to be made. Perhap PI is not suited for this type of applications. That is why I am asking whether I am looking at the wrong application for the described task. If ther are any suggestions on how to acomplish this task your input would be most appreciated.
Thanks
