OdModelerGeometry::evaluate Method (double, double, int, OdGePoint3d&, OdGeVector3dArray&)
Syntax
C++
virtual OdResult evaluate(double dU, double dV, int iDerivDegree, OdGePoint3d& point, OdGeVector3dArray& derivatives) const = 0;
Description
DescriptionEvaluates the position and an arbitrary number of derivatives of the ModelerGeometry object at the specified parameter value (U, V).
Parameters|
Parameters |
Description |
|
dU |
[in] U direction parameter. |
|
dV |
[in] V direction parameter. |
|
iDerivDegree |
[in] Degree of derivatives to evaluate. |
|
point |
[out] Passed-in parameter for returning the evaluated position on the ModelerGeometry object. |
|
derivatives |
[out] Passed-in parameter for returning derivatives array of vectors, in the order of uDeriv, vDeriv, uuDeriv, uvDeriv, vvDeriv. |
ReturnseOk if evaluation is successfully done. If the U or V value is out of range, returns eOutOfRange.
