Bridging [AGGeometryKit](https://github.com/hfossli/AGGeometryKit) with [POP](https://github.com/facebook/pop) for amazing dynamics and animations.

See [this interesting video](https://vimeo.com/93206523) about animation principles by Cento Lodigiani. If you like what you see and want to mimic step #1 and #5 - then this kit is here to help you.

### Installation

New-school: Use the cocoa pod named `AGGeometryKit+POP`.   

Old-school: Grab the files found in `Source`.

## Demo

[See the video on vimeo ](https://vimeo.com/95383807)

## Technology

It does not rely on snapshotting view hierarchy at all. Whenever you update the property `quadrilateral` (defined in [AGGeometryKit](https://github.com/hfossli/AGGeometryKit)) on the `CALayer` you are actually just applying a new `CATransform3D`. This can be done on any view whether it is an interactive UIWebView or just a plain UIImageView. This is totally cost-free! :)

## Interface

Animate each corner independently using these new POPAnimatableProperty's.

```objc

extern NSString * const kPOPLayerAGKQuadTopLeft;

extern NSString * const kPOPLayerAGKQuadTopLeftX;

extern NSString * const kPOPLayerAGKQuadTopLeftY;

extern NSString * const kPOPLayerAGKQuadTopRight;

extern NSString * const kPOPLayerAGKQuadTopRightX;

extern NSString * const kPOPLayerAGKQuadTopRightY;

extern NSString * const kPOPLayerAGKQuadBottomLeft;

extern NSString * const kPOPLayerAGKQuadBottomLeftX;

extern NSString * const kPOPLayerAGKQuadBottomLeftY;

extern NSString * const kPOPLayerAGKQuadBottomRight;

extern NSString * const kPOPLayerAGKQuadBottomRightX;

extern NSString * const kPOPLayerAGKQuadBottomRightY;

@interface POPAnimatableProperty (AGK_POP)

+ (instancetype)AGKPropertyWithName:(NSString *)aName;

@end

```
