-# Task: Texture / Surface Variant Switcher
+# Week 2 Task 2 - Texture Switcher
 
 ## Objective
-Create one object with 2–3 surface variations (e.g., leather, wood, fabric).
+Implement a dynamic surface switcher (Earth/Moon) on a 3D sphere and evaluate the developer experience across Vanilla, R3F, and Thob.
 
 ## Vanilla three.js
--Possible: Yes / Partial / No
+- **Possible**: Yes
--Notes:
+- **Notes**: Requires manual `TextureLoader` management. The developer must ensure textures are fully loaded before assignment to prevent "black frames" or flicker.
--Key concepts:
+- **Key concepts**: Texture Mapping, Asynchronous Loading, UV Wrap.
--Complexity: Easy / Medium / Hard
+- **Complexity**: Medium (Handling external URLs and loading states manually).
 
 ## R3F
--Possible: Yes / Partial / No
+- **Possible**: Yes
--Notes:
+- **Notes**: Minimal implementation using the `useTexture` hook. Caching and loading states are handled out-of-the-box by the framework's architecture.
--What R3F abstracted:
+- **What R3F abstracted**: Async loader management and texture instance reuse.
--Complexity: Easy / Medium / Hard
+- **Complexity**: Easy.
 
 ## Thob Page Builder
--Possible: Yes / Partial / No
+- **Possible**: Yes
--Notes:
+- **Notes**: High visual efficiency using the built-in Media Library and the `RadioGroup` component. Managing 4 variations through a loop keeps the hierarchy much cleaner than individual buttons.
--Builder steps:
+- **Builder steps**: Upload textures to Project Library -> Configure RadioGroup loop -> Map variants to the Material's `map` property.
--Complexity: Easy / Medium / Hard
+- **Complexity**: Easy-Medium (Complexity scale depends on loop logic).
 
 ## Comparison Summary
--Possible in all 3? Yes / Partial / No
+- **Possible in all 3?**: Yes
--Main differences:
+- **Main differences**: Vanilla is imperative/manual; R3F is declarative/hook-based; Thob is visual/library-based.
--Where Thob is better:
+- **Where Thob is better**: Hosting assets and providing a visual gallery for texture selection rather than dealing with URL pathing.
--Where Thob is weaker:
+- **Where Thob is weaker**: Expression "discoverability." Finding proprietary terms like `$context.item_currentItem.id` is difficult without documentation.
--What feels awkward or unclear:
+- **What feels awkward or unclear**: The mass of console warnings generated by the data-binding system during loop interactions.
 
 ## Limitation Type (if any)
--[ ] Editor UX limitation
+- [x] Editor UX limitation (Context visibility)
--[ ] Runtime limitation
+- [x] Documentation/Discovery limitation (Proprietary syntax)
--[ ] Schema / data model limitation
+- [x] Schema / data model limitation (Internal binding redundancy)
--[ ] Component limitation
+- [ ] Asset pipeline limitation
--[ ] Event system limitation
--[ ] Asset pipeline limitation
--[ ] Unknown / needs investigation
 
 ## Workaround
--Is there a workaround?
+- **Is there a workaround?**: Not required for functionality; manual memorization of syntax is currently required to bridge the documentation gap.
--If yes, what is it?
 
 ## Suggested Improvement
--What should improve in Thob?
+- **Primary Optimization**: Implement an **Autocomplete/Dropdown** for expression fields so users can see `$context` options directly in the UI.
--Is it:
+- **Secondary Optimization**: Optimize the runtime renderer to reduce the volume of `method already registered` logs during loops.

-## Difficulty Estimate
--Easy / Medium / Hard
 
 ## Business Value
--Low / Medium / High
+- **High**: Essential for configurators that require "real-world" surface swapping (flooring, upholstery, car finishes).
 
 ## Product Lens
-- Is this pattern useful for real customers? Yes / Partial / No
+- **Is this pattern useful for real customers?**: Yes.
-- What kind of customer use case does this support?
+- **What kind of customer use case does this support?**: Architectural visualization and high-end retail customizers.
-- Does Thob feel strong enough for this use case?
+- **Does Thob feel strong enough for this use case?**: Yes. Visually, the texture rendering is production-quality.
-- What would improve the experience?
+- **What would improve the experience?**: In-editor tooltips explaining the data-binding logic.
 
 ## Recommendation
-Should Thob support this better? Why?.
+Thob is very strong at handling assets. To make it enterprise-ready, they should focus on making the "Logic" layer as visual as the "3D" layer by adding autocompletion for binding expressions.
