Shadow mapping is a core technique in 3D rendering that simulates light source perspectives to generate and display realistic shadows.
It works by first creating a depth map from the light’s viewpoint, where objects closer to the light block those behind, defining shadowed regions.
Widely applied in games, animations, and visual effects, it enhances scene depth and realism by making shadows appear natural.
To optimize, adjusting shadow mapping resolution helps balance shadow quality and rendering speed, ensuring efficient yet lifelike 3D visuals.
