# Week 2 Task 2 - Texture Switcher
|
|
|
|
## Objective
|
|
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
|
|
- **Notes**: Requires manual `TextureLoader` management. The developer must ensure textures are fully loaded before assignment to prevent "black frames" or flicker.
|
|
- **Key concepts**: Texture Mapping, Asynchronous Loading, UV Wrap.
|
|
- **Complexity**: Medium (Handling external URLs and loading states manually).
|
|
|
|
## R3F
|
|
- **Possible**: Yes
|
|
- **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**: Async loader management and texture instance reuse.
|
|
- **Complexity**: Easy.
|
|
|
|
## Thob Page Builder
|
|
- **Possible**: Yes
|
|
- **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**: Upload textures to Project Library -> Configure RadioGroup loop -> Map variants to the Material's `map` property.
|
|
- **Complexity**: Easy-Medium (Complexity scale depends on loop logic).
|
|
|
|
## Comparison Summary
|
|
- **Possible in all 3?**: Yes
|
|
- **Main differences**: Vanilla is imperative/manual; R3F is declarative/hook-based; Thob is visual/library-based.
|
|
- **Where Thob is better**: Hosting assets and providing a visual gallery for texture selection rather than dealing with URL pathing.
|
|
- **Where Thob is weaker**: Expression "discoverability." Finding proprietary terms like `$context.item_currentItem.id` is difficult without documentation.
|
|
- **What feels awkward or unclear**: The mass of console warnings generated by the data-binding system during loop interactions.
|
|
|
|
## Limitation Type (if any)
|
|
- [x] Editor UX limitation (Context visibility)
|
|
- [x] Documentation/Discovery limitation (Proprietary syntax)
|
|
- [x] Schema / data model limitation (Internal binding redundancy)
|
|
- [x] Asset pipeline limitation (Silent 5MB file size upload limit)
|
|
|
|
## Workaround
|
|
- **Is there a workaround?**: Not required for functionality; manual memorization of syntax is currently required to bridge the documentation gap.
|
|
|
|
## Suggested Improvement
|
|
- **Primary Optimization**: Implement an **Autocomplete/Dropdown** for expression fields so users can see `$context` options directly in the UI.
|
|
- **Secondary Optimization**: Optimize the runtime renderer to reduce the volume of `method already registered` logs during loops.
|
|
- **Is it**: Editor, UX, Docs.
|
|
|
|
## Business Value
|
|
- **High**: Essential for configurators that require "real-world" surface swapping (flooring, upholstery, car finishes).
|
|
|
|
## Product Lens
|
|
- **Is this pattern useful for real customers?**: Yes.
|
|
- **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?**: Yes. Visually, the texture rendering is production-quality.
|
|
- **What would improve the experience?**: In-editor tooltips explaining the data-binding logic.
|
|
|
|
## Recommendation
|
|
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.
