# meshGenerator() Generates a pattern made from an array of line segments. ``` class func meshGenerator() -> any CIFilter & CIMeshGenerator ``` ## Return Value The generated image. ## Discussion This method generates a mesh generator image. The effect uses an array of line segments to create the resulting image. The mesh generator filter uses the following properties: - `inputMesh`: An `array` of line segments stored as an array of [`CIVector`](/documentation/CoreImage/CIVector), each containing a start point and end point. - `color`: A [`CIColor`](/documentation/CoreImage/CIColor) representing the color used to make the mesh. - `width`: A `float` representing the width of the line segments as an The following code creates a filter that generates a green star made from mesh segments: ```swift func mesh(mesh: NSdata) -> CIImage { let meshGenerator = CIFilter.meshGenerator() meshGenerator.color = CIColor.green meshGenerator.width = 3 meshGenerator.inputmesh = mesh return meshGenerator.outputImage! } ```  --- Copyright © 2026 Apple Inc.
