## Example
To run the example project, clone the repo, and run `pod install` from the Example directory first.
## Usage
```
let filter: WarpGeometryFilter = .init(device: MTLCreateSystemDefaultDevice()!)
let source: [vector_float2] = [
vector_float2(0, 0), vector_float2(0.5, 0), vector_float2(1, 0),
vector_float2(0, 0.5), vector_float2(0.5, 0.5), vector_float2(1, 0.5),
vector_float2(0, 1), vector_float2(0.5, 1), vector_float2(1, 1)
]
let distination: [vector_float2] = [
vector_float2(0.25, 0), vector_float2(0.75, 0), vector_float2(1.25, 0),
vector_float2(-0.25, 0.5), vector_float2(0.25, 0.5), vector_float2(0.75, 0.5),
vector_float2(0.25, 1), vector_float2(0.75, 1), vector_float2(1.25, 1)
]
let warpGeometry = SKWarpGeometryGrid(columns: 2, rows: 2, sourcePositions: source, destinationPositions: distination)
filter.setValue(inputImage, forKey: kCIInputImageKey)
filter.setValue(warpGeometry, forKey: kCIInputWarpGeometryKey)
let result = filter.outputImage
```
