## Detailed Description

Performs a linear interpolation of two animation clips based on a normalized factor

QLerpClipBlend can be useful to create advanced animation effects based on individual animation clips. For instance, given a player character,, lerp blending could be used to combine a walking animation clip with an injured animation clip based on a blend factor that increases the more the player gets injured. This would then allow with blend factor == 0 to have a non injured walking player, with blend factor == 1 a fully injured player, with blend factor == 0.5 a partially walking and injured player.

See also QBlendedClipAnimator.

## Property Documentation

### blendFactor : float

Specifies the blending factor between 0 and 1 to control the blending of two animation clips.

Access functions:

float | blendFactor() const
void | setBlendFactor(float blendFactor)

Notifier signal:

void | blendFactorChanged(float blendFactor)

### endClip : Qt3DAnimation::QAbstractClipBlendNode *

Holds the sub-tree that should be used as the start clip for this lerp blend node. That is, the clip returned by this blend node when the blendFactor is set to a value of 1.

Access functions:

Qt3DAnimation::QAbstractClipBlendNode * | endClip() const
void | setEndClip(Qt3DAnimation::QAbstractClipBlendNode *endClip)

Notifier signal:

void | endClipChanged(Qt3DAnimation::QAbstractClipBlendNode *endClip)

### startClip : Qt3DAnimation::QAbstractClipBlendNode *

Holds the sub-tree that should be used as the start clip for this lerp blend node. That is, the clip returned by this blend node when the blendFactor is set to a value of 0.

Access functions:

Qt3DAnimation::QAbstractClipBlendNode * | startClip() const
void | setStartClip(Qt3DAnimation::QAbstractClipBlendNode *startClip)

Notifier signal:

void | startClipChanged(Qt3DAnimation::QAbstractClipBlendNode *startClip)
