Light affects how an image is perceived in so many ways. There are shadows and various reflections that bounce off each object. I wonder how expensive it is and how many textural light layers are needed to apply what reflection and light intensity are needed on each individual object. I'm also intrigued with how to get the reflection of other objects that are next to it, besides just the ambiance and background of the room itself. Also, is there a way to adjust a variable or method for the light in the room that can adjust the reflections on each of the objects to make changing the lighting in the room for efficient to see?

Global illumination algorithms, for example photon mapping and ray tracing, can deal with the light reflection between objects in the scene

Adding upon getting the reflections of other objects, are there ways to deal with the lighting based on the refraction/reflection of transparent/translucent materials, such as caustics of glass?

Good discussion, folks! We will study in detail how to create images like this using physically-based light transport and modeling of materials. Stay tuned!
@mylinhvu11 -- at least one way to do what you describe is to change the environmental lighting incident on the scene, and compute the global light transport. This will be an option on a later assignment!
