## Detailed Description

Qt3DAnimation::QAbstractAnimation is an abstract base class for all animations. Qt3DAnimation::QAbstractAnimation can not be directly instantiated, but rather through its subclasses. QAbstractAnimation specifies common properties for all Qt3D animations, such as animation name and type, current position and animation duration, while leaving the actual animating for the subclasses.

## Member Type Documentation

### enum QAbstractAnimation::AnimationType

This enumeration specifies the type of the animation

Constant | Value | Description
--- | --- | ---
`Qt3DAnimation::QAbstractAnimation::KeyframeAnimation` | `1` | Simple keyframe animation implementation for QTransform
`Qt3DAnimation::QAbstractAnimation::MorphingAnimation` | `2` | Blend-shape morphing animation
`Qt3DAnimation::QAbstractAnimation::VertexBlendAnimation` | `3` | Vertex-blend animation
