I wonder how would you translate an object's real-world "transparency" level into digital. It seems pretty straightforward when an object is fully transparent and light is fully transmitted, but I'm not quite sure how a semi-opaque object would work

I think there could be a way to use a constant to measure the transparency of the object. Then as long as the liquid is homogeneous, we can use the length of the ray passing through the object to calculate how much light is lost. In terms of refraction, I think there are also physics laws like $$ {\displaystyle n_{1}\sin \theta {1}=n{2}\sin \theta _{2}} $$ that govern what we will see.
