13. Refraction, reflection and transparency
When we combine 3D models, we need to be concerned with how they interact with each other on a physical level – making sure they only intersect if we want them to, preventing them from crashing into one another, ensuring they’re all sitting flat on the Ground Plane so they cast appropriate shadows.
But if we’ve used transparent or reflective materials, we need to consider how the models behave when seen through each other. How much does a bowl refract the view seen through it? How much reflection should there be on a flat surface? How fast should that reflection fade away? Just how opaque is a glass bottle?
