[Vis5d-users] tcl/vis5d question

 
         I'm running vis5d version 5.2 on a Silicon Graphics O2,
 R12000, IRIX 6.5.  I have compiled vis5d with TCL 8.0 support.
 The problem I encounter is when making trajectories.  If I do
 it interactively there is no problem.  However, if I try to use
 a tcl script, vis5d appears to hang if I specify a time that
 exceeds some certain (unknown) value.  For example, if I specify
 the following:
 
 vis5d_make_traj $dtx 84 34 8 0 1
 
 to make a trajectory at the (y,x,z) point of (84,34,8) at time
 0 (trajectory set 1), it works fine.  I can even specify several
 trajectories at various locations.  I have experimented with the
 start time, and I can use anything up to 120 (I have 365 time
 points in my data set).  For example, I can generate four traj-
 ectories with the following:
 
 vis5d_make_traj $dtx 84 34 8  0 1
 vis5d_make_traj $dtx 84 34 8 10 1
 vis5d_make_traj $dtx 84 34 8 20 1
 vis5d_make_traj $dtx 84 34 8 30 1
 
 But, if I specify the start time as being anything greater than
 120, when I startup vis5d with the tcl script, the program seems
 to be computing something for a long time; the cursor is a clock
 icon and none of the buttons can be selected.  I've let it run
 for over an hour in this state before killing the program.  On
 the other hand, if I startup vis5d without the script, then man-
 ually select a trajectory, I have no problem getting one at any
 timestep, and it seems to plot right away.
 
 Any ideas what's going on here?  Is this a rendering problem, or
 a TCL problem?  Any help would be most appreciated.  Thanks in
 advance.
