Homonym: Occlusions (Blockage)
Occlusions refer to the blockage or obstruction of a passage or opening in various contexts, such as in medicine, optics, and computer graphics. In medicine, an occlusion can occur in blood vessels, leading to reduced blood flow and potential health issues. In optics, it describes how one object can block the view of another, affecting visibility and perception.
In computer graphics, occlusions are important for rendering scenes realistically. When creating 3D environments, understanding how objects block light and visibility helps in producing accurate images. Techniques like occlusion culling are used to improve performance by not rendering objects that are hidden from view.
