# SKWarpGeometryGrid A definition for a grid-based deformation of nodes that conform to [`SKWarpable`](/documentation/SpriteKit/SKWarpable). ``` class SKWarpGeometryGrid ``` ## 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. ## Topics ### Creating a Warp Geometry Grid [`init(columns:rows:)`](/documentation/SpriteKit/SKWarpGeometryGrid/init(columns:rows:)) Creates a warp geometry grid of a specified size. [`init(columns:rows:sourcePositions:destinationPositions:)`](/documentation/SpriteKit/SKWarpGeometryGrid/init(columns:rows:sourcePositions:destinationPositions:)) Creates a warp geometry grid of a specific size and warp translation, in point arrays. [`initWithColumns:rows:sourcePositions:destPositions:`](/documentation/SpriteKit/SKWarpGeometryGrid/initWithColumns:rows:sourcePositions:destPositions:) Creates a warp geometry grid of a specific size and warp translation, in pointers to point arrays. [`gridWithColumns:rows:sourcePositions:destPositions:`](/documentation/SpriteKit/SKWarpGeometryGrid/gridWithColumns:rows:sourcePositions:destPositions:) [`grid`](/documentation/SpriteKit/SKWarpGeometryGrid/grid) Initializes a new empty grid. [`init(coder:)`](/documentation/SpriteKit/SKWarpGeometryGrid/init(coder:)) Tells you when to intialize a grid that was loaded from an archive. ### Animating Warping [Animate the Warping of a Sprite](/documentation/SpriteKit/animate-the-warping-of-a-sprite) Interpolate warping from source to destination warp geometry grids. ### Accessing or Setting Warp Geometry Grid Size [`numberOfColumns`](/documentation/SpriteKit/SKWarpGeometryGrid/numberOfColumns) The object’s number of columns. [`numberOfRows`](/documentation/SpriteKit/SKWarpGeometryGrid/numberOfRows) The object’s number of rows. [`vertexCount`](/documentation/SpriteKit/SKWarpGeometryGrid/vertexCount) The object’s total number of vertices. ### Accessing or Setting Grid Vertices Get or set `float2` values that correspond to individual vertices of the grid. [`destPosition(at:)`](/documentation/SpriteKit/SKWarpGeometryGrid/destPosition(at:)) Returns the destination position of a vertex. [`replacingByDestinationPositions(positions:)`](/documentation/SpriteKit/SKWarpGeometryGrid/replacingByDestinationPositions(positions:)) Returns a copy of this grid, updated with the argument destination positions. [`replacingBySourcePositions(positions:)`](/documentation/SpriteKit/SKWarpGeometryGrid/replacingBySourcePositions(positions:)) Returns a copy of this grid, updated with the argument source positions. [`sourcePosition(at:)`](/documentation/SpriteKit/SKWarpGeometryGrid/sourcePosition(at:)) Returns the source position of a vertex. [`gridByReplacingDestPositions:`](/documentation/SpriteKit/SKWarpGeometryGrid/gridByReplacingDestPositions:) Returns a copy of the receiver with the destination positions replaced by a specified array. [`gridByReplacingSourcePositions:`](/documentation/SpriteKit/SKWarpGeometryGrid/gridByReplacingSourcePositions:) Returns a copy of the receiver with the source positions replaced by a specified array. --- Copyright © 2026 Apple Inc.
