WebSession space vs Unity space. Since an AR device will be used to drive the Camera's position and rotation, you cannot directly place the Camera at an arbitrary position in the Unity scene. Instead, you should position the ARSessionOrigin.This will make the Camera (and any detected features) relative to that as a result.. It is important to keep the Camera and … WebAug 10, 2024 · A raycast is like shining a laser pointer in your scene, to see what the laser hits.

The raycaster component uses the three.js raycaster. The raycaster checks for intersections at a certain interval against a list of objects, and will emit events on the entity when it detects ...
