Just pure math and clever code tricks that fool your brain into seeing layers, shadows, and perspective in a flat 2D image. Programmers use tricks like: - Parallax scrolling (different layers move at different speeds) - Ray marching or signed distance functions - Gradient mapping + noise for fake depth - Vanishing point calculations for perfect perspective - Shader code that si
