Builder Exploration Notes — Task 3: Hover Interaction

Capability Gap Identified

Hover Events: No visible support for onPointerOver / onPointerOut (hover) in the interaction panel
Click Behavior: onClick trigger is present in UI, but actions did not produce visible results during testing
Visual Logic: No clear way to connect user interaction to visual state changes (e.g., color/scale)
Interaction Experience: Scene appears static due to lack of responsive feedback

Observations

Interaction UI exists but execution behavior is unclear or inconsistent
Hover-based interaction is not exposed as a first-class concept
Click interaction may require additional configuration or may be unstable in current environment

Comparison vs Code

Vanilla:
- Requires raycasting and mouse tracking
- Fully controllable but complex
R3F:
- Hover interaction is simple using onPointerOver / onPointerOut
- Very intuitive and minimal code
Thob:
- Hover interaction not available
- Click interaction present but did not behave as expected during testing

Key Insight

The builder currently lacks clear support for continuous pointer-based interactions (like hover) and shows limitations in reliably executing event-based visual updates.

Product Perspective

Hover interactions are essential for user feedback (highlighting, selection cues). The absence or instability of such interactions limits the builder’s ability to create engaging 3D experiences.

Verdict

Strong for static visual setup
Limited for interactive behavior (hover and dynamic feedback)
