The Unit property of the Sphere struct represents a standard unit sphere. This sphere is centered at the origin of the coordinate system and has a radius of 1. It is a static property, meaning it is shared across all instances of the Sphere struct and can be accessed without creating an instance of Sphere.
Use the Unit property when you need a reference to a standard unit sphere in your calculations or simulations. This can be particularly useful in scenarios involving physics simulations, collision detection, or any geometric computations where a unit sphere is required.
// Accessing the Unit sphere Sphere unitSphere = Sphere.Unit; // Example usage: Checking if a point is inside the unit sphere Vector3 point = new Vector3(0.5f, 0.5f, 0.5f); bool isInside = unitSphere.Contains(ref point); // Example usage: Tracing a ray against the unit sphere Ray ray = new Ray(Vector3.Zero, Vector3.One); float distance; bool hit = unitSphere.Trace(ray, 100.0f, out distance);
