Hi,
I am trying to implement an intersection callback function (using the
pfSegsIsectNode function) to avoid jumping on bridges, trees or whatever
while driving on my terrain.

  1) In the definition of the pfSegSet structure, there is a 'void* userData'.
     How can I get a pointer to it in my callback function ?
  2) I am doing several intersections at the same time. The first segment
     is for this ground collision problem. I thought that I could use a call
     to pfQueryHit with a PFQHIT_SEGNUM type, but it seems to return pointer
     values instead of an index number -> is it what I should get? is it a
     bug or am i stupid ? (please, don't answer directly to this last question)

Thank you for any comment, and happy new year!!!!
