exception in oddbspline::getarea()
exception in oddbspline::getarea()
i am using dd 1.14.02 libs.
the code:
code:
oddbsplineptr pspline = oddbspline::createobject();
odgedoublearray weights;
pspline->setnurbsdata( 3, // degree
false, // rational
true, // closed
false, // periodic
controlpoints, // control points
knots, // knots
weights, // weights
1.0000e-10, // control point tolerance
1.0000e-10); // knot tolerance
odgematrix3d matrix;
matrix.settoscaling(0.013888898047845547);
pspline->transformby(matrix);
double area = 0;
odresult result = pspline->getarea(area);
/*
controlpoints =
{

};
knots =
{
0, 0, 0, 0, 1, 1, 1, 2, 2, 2, 2
};
weights = {}; // empty
*/
when executed, results in getarea() throwing an einvalidinput exception. the relevant call stack is:
code:
kernel32.dll!7c81eb33()

if i skip pspline->transformby(matrix) then no exception is generated and i get area = 0.00016050263399227611 with result = eok.
what am i doing wrong?

hi dd guys,
any pointers on this?
thanks,
varun
this is a bug (tolerance issue) in odgepolyline3d::isplanar. it will be fixed in the next release.
vladimir
any dates set for next release yet?
regards,
varun
