There is some proximity function in sources ???? I can't find such a keyword
in listing. I mean something like famouse proximity pattern ?

You should look sources of good old proximity pattern available in MegaPOV.
You can check additional parameters there were available to control finding
nearest intersection point. I think it is much better to have such an addition
as pattern. It could be placed in traditional texture with apropriate map.
Be sure you have readed all proximity related threads on this news server.
There were some further suggestions IIRC.
