What are caustics? A caustic is a beautiful phenomenon in nature where curved surfaces reflect or refract light, thereby concentrating it to a relatively small area. This technique makes it possible to essentially imagine any kind of caustic pattern, for instance, this brain pattern, and it will create the model that will cast caustics that look exactly like that. It also works with sunlight, and you can also choose different colors for your caustics. The authors found their simulations to be in good agreement with reality, therefore the desired caustic patterns can be fabricated faithfully.
