OdModelerGeometry::modifyPositionAndTangent Method
Collapse All
Syntax
C++
virtual OdResult modifyPositionAndTangent(double dU, double dV, const OdGePoint3d& point, const OdGeVector3d* uDeriv, const OdGeVector3d* vDeriv) = 0;
Parameters
Parameters 
Description 
double dU 
[in] U parameter.  
double dV 
[in] V parameter.  
const OdGePoint3d& point 
[in] New location of the point on the surface.  
const OdGeVector3d* uDeriv 
[in] Tangent vector in the U direction.  
const OdGeVector3d* vDeriv 
[in] Tangent vector in the V direction.
 
Returns

eOk if successful or an appropriate error code otherwise.

Description

Adjusts the location and tangent of a point on this ModelerGeometry object with the specified parameter ([U, V]). The local control points are adjusted accordingly. If the pointers uDeriv and vDeriv are equal to NULL, then only the location of the point is adjusted.
