Interactive demo of four Filament View post-processing effects using the
existing View parameter on Scene {}. No new SceneView API required.
Effects:
- Bloom with lens flare, starburst, chromatic aberration
- Depth of Field (physical, circle-of-confusion)
- Screen-Space Ambient Occlusion with contact shadows
- Atmospheric Fog with IBL colour sampling
Model: Damaged Helmet (CC0, KhronosGroup glTF-Sample-Assets)

…ntation Plane visualization: - Change planeRenderer from `anchor == null` to always `true` so ARCore's built-in textured grid remains visible even after a model is placed, giving users a clear view of all detected surfaces. Gesture support (was already wired via isEditable, now documented): - Add inline comments on ModelNode explaining that isEditable = true activates three gestures automatically: single-finger drag to move, two-finger pinch to scale (clamped by editableScaleRange), and two-finger twist to rotate around Y. No additional gesture callbacks are needed. Co-Authored-By: Claude Sonnet 4.6 <noreply@anthropic.com>

Summary
Two improvements to the AR model viewer sample:
1. Persistent plane mesh visualization
planeRendererwas previously set toanchor == null, hiding the plane grid as soon as a model was placed. Changed toplaneRenderer = trueso the ARCore plane grid stays visible at all times — users can see where they can place additional objects even after one model is already in the scene.2. Gesture support documented
Confirmed that
isEditable = trueonModelNodealready wires up all three touch gestures internally viaGestureDetector:editableScaleRange)Added inline comments to document this so future developers don't need to re-investigate.
