enum ETangentMode

Key tangent mode for cubic interpolation.

Enumerator
eTangentAuto	Auto key (spline cardinal).
eTangentTCB	Spline TCB (Tension, Continuity, Bias)
eTangentUser	Next slope at the left equal to slope at the right.
eTangentGenericBreak	Independent left and right slopes.
eTangentBreak	Independent left and right slopes, with next slope at the left equal to slope at the right.
eTangentAutoBreak	Independent left and right slopes, with auto key.
eTangentGenericClamp	Clamp: key should be flat if next or previous key has the same value (overrides tangent mode).
eTangentGenericTimeIndependent	Time independent tangent (overrides tangent mode).
eTangentGenericClampProgressive	Clamp progressive: key should be flat if tangent control point is outside [next-previous key] range (overrides tangent mode).

    };

enum EInterpolationType

Key interpolation type.

Enumerator
eInterpolationConstant	Constant value until next key.
eInterpolationLinear	Linear progression to next key.
eInterpolationCubic	Cubic progression to next key.

        eInterpolationConstant = 0x00000002,    
        eInterpolationLinear = 0x00000004,      
        eInterpolationCubic = 0x00000008        
    };

enum EWeightedMode

Weighted mode.

Enumerator
eWeightedNone	Tangent has default weights of 0.333; we define this state as not weighted.
eWeightedRight	Right tangent is weighted.
eWeightedNextLeft	Left tangent is weighted.
eWeightedAll	Both left and right tangents are weighted.

Definition at line 57 of file fbxanimcurve.h.

Definition at line 66 of file fbxanimcurve.h.
