i only see a black screen The shapes in the $3$D scene are all white and look flat. The goal is to add two different light sources at different positions to improve the look of the scene and define the $3$D shapes better. Also, add some color to one of the lights to bring more color into the scene. The following picture shows an example $3$D scene after the two lighting sources have been added.Create code to address the required functionality. Apply logic and proper syntax to code. All code should be well commented.
