[ODE] Fwd: [ opende-Patches-1547895 ] HeightField Float Precision Bugfix

[David Walters]

I've just checked in an equivalent for this patch using the global
dEpsilon defined in config.h - Please can the authour of this patch
confirm that this problem is solved - your epsilon values were larger
I think thant FLT_EPSILON / DBL_EPSILON.

If it still fails - please provide the configuration ( dimensions /
edge vertex counts) of the heightfield that would cause this assert to
trigger - and on what plaforms / precision configurations you are
using.

Regards,
Dave.
