# Camera, Lighting, and Effects Determine the camera position and lighting for the current session, and apply effects, such as occlusion, to elements of the environment. ## Topics ### Camera Get details about a user’s iOS device, like its position and orientation in 3D space, and the camera’s video data and exposure. [`class ARCamera`](/documentation/ARKit/ARCamera) Information about the camera position and imaging characteristics for a given frame. ### Lighting Effects [Adding realistic reflections to an AR experience](/documentation/ARKit/adding-realistic-reflections-to-an-ar-experience) Use ARKit to generate environment probe textures from camera imagery and render reflective virtual objects. [`class AREnvironmentProbeAnchor`](/documentation/ARKit/AREnvironmentProbeAnchor) An object that provides environmental lighting information for a specific area of space in a world-tracking AR session. [`class ARLightEstimate`](/documentation/ARKit/ARLightEstimate) Estimated scene lighting information associated with a captured video frame in an AR session. [`class ARDirectionalLightEstimate`](/documentation/ARKit/ARDirectionalLightEstimate) Estimated environmental lighting information associated with a captured video frame in a face-tracking AR session. ### Occlusion [Occluding virtual content with people](/documentation/ARKit/occluding-virtual-content-with-people) Cover your app’s virtual content with people that ARKit perceives in the camera feed. [Effecting People Occlusion in Custom Renderers](/documentation/ARKit/effecting-people-occlusion-in-custom-renderers) Occlude your app’s virtual content where ARKit recognizes people in the camera feed by using matte generator. [Visualizing and interacting with a reconstructed scene](/documentation/ARKit/visualizing-and-interacting-with-a-reconstructed-scene) Estimate the shape of the physical environment using a polygonal mesh. [`class ARMatteGenerator`](/documentation/ARKit/ARMatteGenerator) An object that creates matte textures you use to occlude your app’s virtual content with people, that ARKit recognizes in the camera feed. --- Copyright © 2026 Apple Inc.
