Subject: [info-performer] FCS obj disappear when original location not in
FOV
(I've submitted a very similar post to the listing, but I didn't get my own
post via email so I assumed it didn't go out. So, I'm trying
again...)
I've recently started using engines, fluxes and FCS nodes. But I have an odd
behavior.
I bring in a .flt model to a pfNode.
Using the model node, I add it to an FCS node that I created with a C
version of fcs_animate example. I now have a moving airplane.
PROBLEM:
I then move my eye point around. If the original location of the object
leaves the FOV, my moving airplane disappears. Naturally, if the airplanes
move such that the original location and the (now displaced due to
animation) airplane can't both be seen in a frame, all traces of the
airplane in the visualation are gone.
Thoughts:
-I was unable to port one line from the fcs_animate example:
fcs->setBound(&bsph, PFBOUND_STATIC); Would this be an issue? Also, I
couldn't find the C version of this function after some time searching
through the .h files. Any help here, also, would be appreciated.
