Planet Nine Spaceship Creator
Generate interactive 3D spaceship visualizations showcasing the Planet Nine ecosystem as a rotating sphere with continents, dynamic lighting, and smooth controls.
What This Skill Does
Creates a complete THREE.js-based 3D visualization with:
Interactive sphere with mouse/touch rotation controlsDual-hemisphere materials (screen side + ocean side)Continent mapping system for ecosystem componentsTypewriter text effect with canvas textureSmooth animations and responsive designZero framework dependencies (pure THREE.js + vanilla JS)Instructions
1. Analyze Requirements
When the user requests a spaceship visualization:
Confirm the project name and themeAsk if they want the Planet Nine ecosystem mapping or custom continentsDetermine if additional interactive elements are neededVerify target browsers (ensure WebGL support)2. Project Structure Setup
Create a minimal file structure:
```
project-name/
├── index.html # Main HTML with embedded styles
├── script.js # Complete THREE.js application
└── CLAUDE.md # Project documentation
```
**No build tools, no package.json, no frameworks.**
3. Generate index.html
Create HTML file with:
THREE.js CDN import (`https://cdn.jsdelivr.net/npm/[email protected]/build/three.min.js`)Embedded CSS for full-screen canvas and loading screenMinimal DOM structure (loading div, canvas via THREE.js)Script tag linking to `script.js`**CSS Requirements:**
`body`: `margin: 0; overflow: hidden; background: #000`Canvas: full viewport (`width: 100vw; height: 100vh`)Loading screen with centered text, fade-out animation4. Generate script.js
Implement complete THREE.js application with these components:
#### Scene Initialization
`PerspectiveCamera` (FOV 75, responsive aspect ratio)`WebGLRenderer` (antialiasing enabled, black background)Window resize handler for responsive behavior#### Sphere Geometry
`SphereGeometry` (radius ~2.5, segments 128 for smooth surface)Multi-material approach: - **Screen Side**: Glossy `MeshPhongMaterial` (black with high shininess)
- **Ocean Side**: Green-tinted `MeshPhongMaterial` (representing living Planet Nine)
Position camera at appropriate distance (z ~6-8)#### Lighting System
Create four-light setup:
1. **AmbientLight**: Overall illumination (intensity ~0.3)
2. **Main DirectionalLight**: Front light (white, intensity ~0.8)
3. **Secondary DirectionalLight**: Side definition light (intensity ~0.3)
4. **Green PointLight**: Atmospheric glow for text side (position near screen hemisphere)
#### Canvas Texture for Text
Create offscreen `<canvas>` element (1024x512 or similar)Implement typewriter effect for "Hello World" or custom textApply glow effect (shadow blur, multiple text renders)Add blinking cursor animationMap canvas to `CanvasTexture` and apply to material#### Continent System
Create method to add continents:
Input: name, color, latitude/longitude, sizeConvert lat/lon to 3D sphere coordinatesGenerate `PlaneGeometry` for continent surfaceCreate `RingGeometry` for purple boundaryOrient planes to follow sphere curvature (lookAt sphere center)Add as child objects to sphere (rotate with sphere)**Planet Nine Default Continents:**
The Stack (Brown, ~30°N, 0°E)The Nullary (Dark Slate Gray, ~30°N, 90°E)allyabase (Dark Olive Green, ~30°N, 180°E)The Advancement (Indigo, ~30°N, 270°E)#### Interactive Controls
Implement mouse/touch rotation:
Track pointer down/move/up eventsCalculate delta movementApply rotation to sphere with smooth interpolation (lerp factor ~0.05)Continue rotation momentum after releaseSupport both mouse and touch events for mobile#### Animation Loop
Use `requestAnimationFrame` for 60fpsUpdate any animations (typewriter, cursor blink)Render sceneApply smooth rotation interpolation5. Generate CLAUDE.md Documentation
Create comprehensive documentation including:
**Overview**: Project description and Planet Nine context**Architecture**: Core design principles (no frameworks, Planet Nine libraries only, keep it simple)**File Structure**: Complete file listing**Features**: Detailed technical breakdown of 3D visualization, materials, lighting, continents**Development Guidelines**: Code standards, future enhancement rules (Planet Nine integration only)**Technical Notes**: Performance considerations, browser compatibility**Usage**: How to run (just open index.html)6. Code Standards
Enforce these rules:
**ES6+ JavaScript**: Use classes, arrow functions, const/let**No TypeScript**: Pure vanilla JavaScript only**No Build Process**: Direct browser execution**Single Responsibility**: Each method handles one specific task**Clear Naming**: Descriptive variable and method names**Comments**: Explain non-obvious THREE.js concepts (coordinate systems, materials, lighting)7. Testing Checklist
Before delivery, verify:
[ ] Sphere renders correctly with both hemispheres[ ] Continents positioned accurately on surface[ ] Mouse/touch rotation works smoothly[ ] Typewriter effect displays correctly[ ] Responsive design works on mobile[ ] No console errors[ ] Loading screen fades out after initialization[ ] All materials and lights render as intended8. Customization Guidance
Advise user on common customizations:
**Change text**: Modify typewriter string in script.js**Add continents**: Call `addContinent()` with new coordinates/colors**Adjust lighting**: Modify light intensities and positions**Change colors**: Update material properties (color, emissive, shininess)**Resize sphere**: Adjust geometry radius and camera position**Speed rotation**: Modify interpolation factor in animation loopExamples
Example 1: Default Planet Nine Spaceship
**User Request:** "Create a Planet Nine spaceship visualization"
**Output:**
`index.html` with THREE.js CDN and full-screen canvas`script.js` with complete spaceship implementation (dual-hemisphere sphere, 4 continents, typewriter "Hello World")`CLAUDE.md` with full documentationExample 2: Custom Theme Spaceship
**User Request:** "Make a spaceship showing our company's three products as continents"
**Output:**
Same file structureCustom continents at specified coordinates with user-chosen colorsTypewriter text shows company nameDocumentation adapted to custom themeExample 3: Minimal Moon Visualization
**User Request:** "Just a simple rotating moon with craters"
**Output:**
Simplified version: single-material sphere (gray)Crater continents (dark gray circles)No typewriter effectSimplified lighting (ambient + single directional)Important Constraints
1. **No Frameworks**: Never add React, Vue, Angular, Svelte, etc.
2. **No Build Tools**: No webpack, Vite, Parcel, or bundlers
3. **No Package Managers**: No npm, yarn, or pnpm required
4. **THREE.js Only**: Only external dependency is THREE.js CDN
5. **Planet Nine Ecosystem**: Future integrations must use official Planet Nine libraries (sessionless, MAGIC, teleportation, Covenant, BDO)
6. **Mobile-First**: All interactions must work on touch devices
7. **Performance**: Maintain 60fps, use geometry reuse, avoid memory leaks
Planet Nine Integration (Future)
When user requests additional features, only integrate these official Planet Nine libraries:
**sessionless**: Cryptographic authentication**MAGIC Protocol**: Transaction capabilities**teleportation**: Content discovery**Covenant**: Contract visualizations**BDO**: Configuration persistence**Never suggest** non-Planet Nine third-party libraries, state management frameworks, or complex toolchains.
Delivery Format
Provide complete, working files:
1. Full `index.html` (ready to open in browser)
2. Full `script.js` (complete THREE.js implementation)
3. Full `CLAUDE.md` (comprehensive documentation)
User should be able to immediately open `index.html` and see a working 3D spaceship with smooth interactions.
