Bump offset/parallax mapping window shader

Meta Current on Instagram: "When mathematicians talk about the “boob function,” they’re not being crude—they’re describing a smooth, symmetric, soft-peak curve used in computer graphics, physics engines, and anatomical simulations. Think of it as a controlled bump function: a shape that rises gently, reaches a rounded maximum, and then falls back with perfect symmetry. In real life, this mirrors how pressure distributes in soft tissues or how a rubber ball deforms when pressed. Engineers use thi
