#### swift reflections how to construct a new struct Stack Overflow

Using the generic placeholder T to **construct** a new instance fails with the error 'Aable' cannot be constructed because it has no accessible initializers. Is that even possible? Could it be achieved using reflections or some sort of introspection? protocol Aable { var name: String { get } }.

#### How to construct ray reflection from convex curved surface

I'm trying to understand how to **construct** the **reflection** path of a ray from a curved surface. Here's the basic setup: In a 2D space, assume a point S is the source of a ray and point R is the receiver. An arbitrary convex line is located in space and acts as a perfect reflector for incoming rays.

#### How to construct a 30 degree angle with Math Open Reference

This page shows how to **construct** (draw) a 30 degree angle with compass and straightedge or ruler. It works by first creating a rhombus and then a diagonal of that rhombus. Using the properties of a rhombus it can be shown that the angle created has a measure of 30 degrees.
