evaluateInteriorPointV4() return value ?

[nicholas_yue]

Hi,

 

  I came across this method which I am planning to use but there is no document about the return values.

 

virtual int          evaluateInteriorPointV4(UT_Vector4 &pos,

                                       fpreal u, fpreal v, fpreal w = 0) const;

 

  I am guessing there must be a reason for not simply returning a boolean.

 

Cheers

evaluateInteriorPointV4(UT_Vector4 &pos,......)

 

Value of sampled point returns by reference (&pos). Function returns 0 if evaluation is OK, -1 otherwise.
