CircleEmitter

public class CircleEmitter : Circle, Emitter

A circle that emits rays radiating out from its perimiter

  • Angle of the step between emitted rays

    The value is clamped to a minimum of 0

    Declaration

    Swift

    public var rayStep: Int { get set }

  • Visual style for the emitter’s rays

    Declaration

    Swift

    public var style: RayTraceStyle

  • Instantiate a new emitter at the specified coordinates

    Declaration

    Swift

    public init(x: Double, y: Double, radius: Double, rayStep: Int)

    Parameters

    x

    Center X coordinate
    y

    Center Y coordinate
    radius

    Radius of the emitter
    rayStep

    Angle between emitted rays

  • Process the ray casting operations for this emitter.

    This method calculates the paths of the emitter’s rays, but does not draw them. Any previous rays will be overwritten.

    Declaration

    Swift

    public func run(objects: [RayTracable])

    Parameters

    objects

    The objects with which the rays will interact

  • Draw the paths taken by the emitter’s rays.

    This method does not perform any ray tracing.

    Declaration

    Swift

    public func draw()
