AR Hit Testing: From a Screen Tap to Stable Object Placement
Turn geometric candidates into an understandable placement flow with previews, confirmation, adjustment, and recovery.
Read the field noteTOPIC COLLECTION
A practical path from candidate geometry to believable placement. Read hit testing before anchors, then explore depth and occlusion. The articles keep placement, attachment, and visual integration separate so you can test each stage. Pay particular attention to missing data, repositioning, and the difference between a successful local demonstration and a verified deployment.

Turn geometric candidates into an understandable placement flow with previews, confirmation, adjustment, and recovery.
