'''Occlusion culling''' is a [[rendering]] optimization technique that prevents [[graphics]] systems from processing and drawing [[geometry]] hidden behind other objects in a scene. Unlike [[view frustum culling]] which only excludes objects outside the camera's [[field of view]], occlusion culling identifies and skips objects within the frustum but obscured by foreground geometry.<ref>Unity Technologies.

Medium. https://medium.com/@Umbra3D/introduction-to-occlusion-culling-3d6cfb195c79</ref> This technique represents one of the most critical optimizations for [[virtual reality]] and [[augmented reality]] applications, where maintaining 90-120 [[frames per second]] is essential to prevent motion sickness and preserve [[immersion]].<ref>Road to VR.
