Collapse All
Syntax
C++
virtual OdResult evaluate(double dU, double dV, int iDerivDegree, OdGePoint3d& point, OdGeVector3dArray& derivatives) const = 0;
Parameters
Parameters 
Description 
double dU 
[in] u direction parameter.  
double dV 
[in] v direction parameter.  
int iDerivDegree 
[in] The degree of derivatives to evaluate.  
OdGePoint3d& point 
[out] A passed-in parameter for returning the evaluated position on the ModelerGeometry object.  
OdGeVector3dArray& derivatives 
[out] A passed-in parameter for returning derivatives array of vectors, in the order of uDeriv, vDeriv, uuDeriv, uvDeriv, vvDeriv.
 
Returns

Returns eOk if evaluation is successfully done. If the u or v value is out of range, returns eOutOfRange.

Description

Evaluates the position and an arbitrary number of derivatives of the ModelerGeometry object at the specified parameter value (u, v).
