AFAICT these two functions:
virtual void
GeoVectorProperty::getValue(Vec3f &val, const UInt32 index) const;
virtual void
GeoVectorProperty::setValue(const Vec3f &val, const UInt32 index);
can simply be removed, since they offer no advantage over the member
function templates. When the untyped geo properties are used, the data
can only be accessed through get/setGenericValue and one has to pay for
two conversions (first to MaxTypeT then to ExternalType).
So, could you try and remove these functions to see if that solves your
problem as well? Or am I overlooking something ?
Thanks,
Carsten
