HeightmapIterator

import Heightmap

Data structures for generating and exposing a height map.

struct Heightmap

A two-dimensional array of unit-values, used to represent a height map.

subscript(x: Int, z: Int) -> Float { get }

Returns the floating point value at the width and depth you provide.

subscript(xz: XZIndex) -> Float { get }

Returns the floating point value at the width and depth you provide.

init(_ contents: [Float], width: Int)

Creates a new height map from the collection of floating point values that you provide.

init(_ contents: [Float], width: Int, depth: Int)

Creates a new height map from the collection of floating point values that you provide.

init(bytes: [UInt8], width: Int)

Creates a new height map from the collection of bytes that you provide.

init(from decoder: any Decoder) throws

init(normalizing: [Float], width: Int)

Creates a new height map normalizing the collection of floating point values that you provide to unit values.

var contents: [Float]

The linear interior contents of the two-dimensional array.

var endIndex: Int { get }

let height: Int

The height of the array.

var startIndex: Int { get }

let width: Int

The width of the array.

subscript(linearindex: Int) -> Float { get set }

func index(after i: Int) -> Int

func makeIterator() -> HeightmapIterator

func normalize(expand: Bool = false) -> Heightmap

Returns a height map with the values normalized to map between 0.0 and 1.0.

mutating func normalized(expand: Bool = false)

Changes the contents of the height map to normalize the values between 0 and 1.0.

typealias Index = Int

typealias Iterator = HeightmapIterator

protocol IteratorProtocol<Element>

A type that supplies the values of a sequence one at a time.
