DirectXTK SimpleMath

Ray class modeled after the XNA Game Studio 4 (Microsoft.Xna.Framework.Ray) math library.

Header

#include <SimpleMath.h>

Initialization

using namespace DirectX::SimpleMath;

Ray r;                                // Create a ray starting at the origin
                                      // pointing in positive Z
Ray( Vector3(1,2,3), Vector3(0,1,0 ); // Creates a ray at 1,2,3
                                      // pointing in positive Y

Fields

  • position: Position of the ray
  • direction: Direction vector of the ray

Methods

  • Comparison operators: == and !=
  • Intersects: Performs intersection tests of the ray against a collision type, a triangle, or a Plane.
