PerspectiveTransform caclulates Core Animation `CATransform3D` matrix for view projection in 3D. It can be used to place views within given image visual perspective.
PerspectiveTransform caclulates homogeneous transformation matrix for a view 3D projection in 2D. It can be used to place views within given image visual perspective using Core Animation `CATransform3D` and [`CALayer.tranform`](https://developer.apple.com/documentation/quartzcore/calayer/1410836-transform). Projection is caclulated between source and destination perspectives that are defined by 4 corners, assuming they form a [Quadrilateral](https://en.wikipedia.org/wiki/Quadrilateral).
