OdGeNurbCurve2d::setEvalMode Method
Collapse All
Syntax
C++
OdGeNurbCurve2d& setEvalMode(bool evalMode = false);
Parameters
Parameters 
Description 
bool evalMode = false 
[in] Input state of the evaluation mode. 
Returns

Reference to this OdGeNurbCurve2d object.

Description

Sets the evaluation mode. 

 

Remarks

If evalMode is false, there is no optimization of an internal evaluator. This mode generally should be used if only one or two values per interval between two consecutive knots are evaluated. 

If evalMode is true, then the evaluator optimization is turned on. This provides better performance if three or more values per knot interval are computed. 

Currently not implemented.
