To place AR objects on real-world surfaces, you use ray casting to perform hit tests against detected environments. This enables stable grounding and precise object spawning where the user points in the AR space.

Yes, depth-aware placement utilizes surface normals to achieve natural alignment on floors and tables. This ensures AR objects conform accurately to the physical geometry of detected real-world surfaces.

Yes, WorldQueryModule is required to execute real-time surface hit testing for AR object placement. It must be available within your LensStudio TypeScript workflow to manage hit-test sessions.

The best way to manage ray input for surface placement is using SIK-based ray input integrated with your LensStudio TypeScript workflows. This combination handles hit-test sessions and rendering for AR object spawning.

AR object placement fails without depth data because the ray casting mechanism relies on depth testing to detect real-world surfaces. Accurate hit tests require depth information to calculate surface normals and grounding.
