getclosestpointto
hi.
i want to get most closest point at nurbscurve.
odgenurbcurve3d::getclosestpointto() needs odgepointoncurve3d, but odgepointoncurve3d is not defined function of odgepointent3d::point3d(void) const.
and i can't compile code.
do i need to make the inherited class?
even if it succeeds in compile, linkerror(error lnk2019 odgecurve3d::getclosestpointto()) is displayed.
can't i use the function from odgenurbcurve3d?
code:
odgenurbcurve3d nc;
if (edge.getcurveasnurb(nc))
{
int num_cp = nc.numcontrolpoints();
for(unsigned int i=0; i<num_cp; i++)
{
odgepoint3d cps;
cps = nc.controlpointat(i);
odgepoint3d samplepoint;
odgepointoncurve3d poc; // compile error
nc.getclosestpointto(cps, poc); // link error
samplepoint = poc.point();
........
}
}
i using dd 1.13,vc2003.
thank you for your consideration.
