Occlusion maps are a type of texture map used in computer graphics to simulate the occlusion, or blocking, of light on a surface. This technique is commonly used in 3D rendering to create more realistic and detailed images by taking into account how light interacts with objects in a scene.
Occlusion maps work by assigning darker values to areas of a surface that are likely to be shadowed or blocked from the light source, and lighter values to areas that are more exposed. This helps to create the illusion of depth and dimension in a 3D environment, as shadows and shading play a crucial role in how we perceive the shape and form of objects.
By using occlusion maps, artists and developers can enhance the visual quality of their 3D models and scenes without having to rely solely on complex lighting setups. This technique is especially useful in creating realistic textures for surfaces such as rocks, bricks, and other objects with intricate details that benefit from the added depth and definition provided by occlusion mapping.
Overall, occlusion maps are a powerful tool in the world of computer graphics, allowing for more immersive and visually appealing 3D environments that closely mimic the way light behaves in the real world.
