用六种算法实现maya动画曲线光滑

在使用动补数据的时候，经常会有手脚等部位的抖动，特意写了个command，直接将动画曲线平滑一下，不用动画师大量的进行手调，下面是代码：

smoothAnimationCurveCmd.h

 

#ifndef _smoothAnimationCurve_
#define _smoothAnimationCurve_

#include <maya/MPxCommand.h>
#include <maya/MObject.h>
#include <maya/MSyntax.h>
#include <maya/MFnAnimCurve.h>
#include <maya/MAnimCurveChange.h>
#include <maya/MItDependencyNodes.h>
#include <maya/MSelectionList.h>
#include <maya/MItSelectionList.h>

class SmoothAnimationCurveCmd: public MPxCommand
{
public:
    SmoothAnimationCurveCmd();
    virtual ~SmoothAnimationCurveCmd();
    virtual MStatus doIt( const MArgList& );
    virtual MStatus redoIt();
    virtual MStatus undoIt();
    virtual bool isUndoable() const { return true; }
    static void *creator(){ return new SmoothAnimationCurveCmd; }
    static MSyntax newSyntax();
    MStatus compliceMethod( MFnAnimCurve &fnAnim, MAnimCurveChange *animCache );
    MItSelectionList getSelectObjectsAnimCurves(); 

private:
    MString type;
    int method;
    unsigned int iterations;
    MAnimCurveChange* pAnimCache;

};

#endif
