# SKWarpGeometryGrid

A definition for a grid-based deformation of nodes that conform to SKWarpable.

## Declaration

```swift
class SKWarpGeometryGrid
```

## Mentioned in

Animate the Warping of a Sprite Warping SpriteKit Content By Using an Effect Node

## Overview

Overview An SKWarpGeometryGrid exposes a 2D array of source positions, and set of destination positions with matching size, that allow you to define which sections of a node should be translated from the source positions to the destination positions. Conceptually, this forms two grids—a source grid and a destination grid—where the visual warping is accomplished by stretching or shrinking each section of the node as the source positions of the grid interpolate to their corresponding destination positions.
