in the camera class, i believe there is a function to return a ray from the mouse position. i can leave them the keys to my business and the job gets done on-time, every time and i know i have nothing to worry about. we have opportunities to share information. like the feel and comfort of the sock. i just hope we don’t get chopped off. i'd probably want to leave the planet as well. some might argue that if customers don’t come inside you lose a chance for a second sale.
