Syntax
C++
virtual OdResult evaluate(double dU, double dV, OdGePoint3d& pos, OdGeVector3d& uDeriv, OdGeVector3d& vDeriv) const = 0;
Description
DescriptionEvaluates the position and first derivatives on the ModelerGeometry object at the specified parameter value (U, V).
Parameters|
Parameters |
Description |
|
dU |
[in] U direction parameter. |
|
dV |
[in] V direction parameter. |
|
pos |
[out] Passed-in parameter for returning the evaluated position on the ModelerGeometry object. |
|
uDeriv |
[out] Passed-in parameter for returning the first derivative with respect to U. |
|
vDeriv |
[out] Passed-in parameter for returning the first derivative with respect to V. |
ReturnseOk if evaluation is successfully done. If the U or V value is out of range, returns eOutOfRange.
