[osg-users] division by zero in osgParticle/FluidProgram.cpp

[Csaba Halász]

Hi!

If wind_accel has zero length, then line 43

 double critical_dt2 = relative_wind.length2()/wind_accel.length2();

will attempt a divide by zero. A simple fix would be to check for zero
but that would still leave the possibility of an overflow if the
divisor is small. So a more clever check would be nice. Any
suggestions?
