Overview

Holds the result of a point query made on a Shape or Space.

#distance : Float64
The distance to the point (negative if the point is inside the shape).
#distance=(distance : Float64)
#gradient : Vect
The gradient of the signed distance function.
#gradient=(gradient : Vect)
#point : Vect
The closest point on the shape's surface (in world space coordinates).
#point=(point : Vect)
#shape : Shape
The nearest shape
#shape=(shape : Shape)

def self.new(shape : Shape, point : Vect, distance : Float64, gradient : Vect) #

def distance : Float64 #

The distance to the point (negative if the point is inside the shape).

def distance=(distance : Float64) #

def gradient : Vect #

The gradient of the signed distance function.

The value should be similar to point/distance, but accurate even for very small values of #distance.
