USE TURBOWARP! https://turbowarp.org/projects/1151090298 Control WASD to move,arrow keys to look around. When you want to move the camera:pressing space key and move to set the camera. When you want to render the sphere:release pressing space key to render. Or,press R key to render the image. (I recommend press R key.) If you want to keep the result of rendering, take the screenshot. I hope you enjoy and eat sandwitch.
