Ray.dir is a member variable in the C++ programming language that represents the direction of a ray in a three-dimensional space. It is commonly used in ray tracing algorithms and graphics programming to determine the path a ray takes. This variable typically stores a vector that specifies the x, y, and z components of the ray's direction. The Ray.dir variable is essential for calculating intersections, reflections, and refractions of rays in various simulations and rendering processes.
