Usage: you must use this class as is. You should never derive it.
public class CATCrvEvalCommand
Class representing a command for computing a multiple evaluation
on points of a CATCurve.
The evaluation is
performed by the Eval method of the CATCurve interface and results
are handled by the CATCrvEvalLocal class.
Basic evaluators can be directly used as in the following examples:
CATCrvEvalLocal EvalResult;
CATCrvParam Parameter ;
Curve->GetStartLimit(Parameter) ;
Curve->Eval(Parameter, CATCrvEvalCommand::EvalPoint , EvalResult) ; // Evaluate point
Curve->Eval(Parameter, CATCrvEvalCommand::EvalFirstDerivative , EvalResult) ; // Evaluate first derivative
Curve->Eval(Parameter, CATCrvEvalCommand::EvalSecondDerivative , EvalResult) ; // Evaluate second derivative
Curve->Eval(Parameter, CATCrvEvalCommand::EvalThirdDerivative , EvalResult) ; // Evaluate third derivative
Curve->Eval(Parameter, CATCrvEvalCommand::EvalUpToFirstDerivative , EvalResult) ; // Evaluate all derivatives up to first derivative
Curve->Eval(Parameter, CATCrvEvalCommand::EvalUpToSecondDerivative , EvalResult) ; // Evaluate all derivatives up to second derivative
Curve->Eval(Parameter, CATCrvEvalCommand::EvalUpToThirdDerivative , EvalResult) ; // Evaluate all derivatives up to third derivative
The evaluation types are not exclusive. You can ask for other types
by using the Order method, or put the command to
No Evaluation with the Reset method.
