Week 1 — General Notes & Personal Summary

Milestone Recap: Tasks 1–4

Task 1 (Material Color): Handled color changes imperative (Vanilla), declarative (R3F), and UI-driven (Thob).
Task 2 (Texture Mapping): Successfully applied checkerboard and URL-based textures. Thob speed was the highlight here.
Task 3 (Hover Feedback): Identified a major gap—Hover is standard in code but missing from the builder UI.
Task 4 (Click Toggle): Discovered that the onClick interaction engine is currently unstable/broken in the builder.

The Thob Advantage: Setting up a 3D scene (adding a cube + lighting + texture) in the builder is lightning-fast. What takes a 10-minute Vite setup in Vanilla takes 2 minutes in the Thob UI.
The Interactivity Threshold: As soon as we moved from "Static Visuals" to "Interactive Behavior," the strength shifted back to R3F. The builder's UI for interactions exists, but the execution logic isn't there yet.

Writing the Raycaster manually in Vanilla felt outdated and boilerplate-heavy compared to the clean onPointerOver props in R3F.
Insight: Thob would benefit immensely by mirroring R3F's declarative event model (simple triggers linked to property changes).

The most valuable part of this week's sprint was identifying that:

Hover (PointerOver/Out): Is not just "hidden"—it's currently missing as a first-class feature in the Thob engine.
Click (Interaction Dispatcher): Is unreliable. Even when wired correctly in the UI, it doesn't always fire in the runtime.
CORS/Asset Linking: External URL textures are prone to browser blocking, making internal "Project Library" uploads the only safe path for now.
