OdModelerGeometry::setControlPoints Method
|
Parameters |
Description |
|
int iUCount |
[in] The new value of the quantity of control points in the u direction. |
|
int iVCount |
[in] The new value of the quantity of control points in the v direction. |
|
const OdGePoint3dArray& points |
[in] New array of control points (in WCS coordinates). |
Returns eOk if control points were successfully set or an appropriate error code in the other case.
Sets the control points.
The new quantity of control points in the u and v direction must be equal to the current values. New control points are allocated in an AcGePoint3d array. The column indexes are for the v direction, and row indexes are for the u direction. For example, if the surface has n control points in the u direction and m control points in the v direction, the array looks like [0,0], [0,1], ...[0,vCount-1], ..., [uCount-1,0], [uCount-1,1], ...[uCount-1,vCount-1].
