Gemini 3 Pro vs Sonnet 4.5

Gemini 3 Pro has launched, and there's been a lot of interest in how it stacks up against Claude Sonnet 4.5 in practical use. The examples below show how both models respond to the same prompts. The prompts we used are also included, so you can try them yourself in Verdent.

Interactive 3D Solar System Explorer

Gemini 3 Pro

Sonnet 4.5

Role: Expert Creative Frontend Developer & Three.js Specialist

Task: Create a high-end, interactive 3D Solar System Explorer as a single HTML file.

Language: All UI text and planet descriptions must be in English.

Core Constraints:

1. Single File: All HTML, CSS, and JavaScript must be in one file.

2. No External Image Assets: Do NOT use `textureLoader.load('url')` because external images often fail to load or have CORS issues. Instead, you MUST implement a `TextureFactory` class that procedurally generates textures using the HTML5 Canvas API (2D context) and converts them to `THREE.CanvasTexture`.

3. Libraries: Use Three.js (r128), OrbitControls, and Tween.js via CDN.

Technical Specifications:

1. Procedural Texture Generation (The "Magic" Part):
   • Create a TextureFactory object.
   • Sun: Use a custom THREE.ShaderMaterial (GLSL) to create a glowing, animated plasma surface effect.
   • Gas Giants (Jupiter, Saturn): Generate banded textures using Canvas gradients and sin/cos waves on the canvas context.
   • Terrestrial (Mercury, Mars, Venus): Generate noise/crater-like textures using random circle drawing on the canvas.
   • Earth: Generate a complex texture with blue oceans, green continent blobs, and semi-transparent white clouds.
2. 3D Scene Setup:
   • Dark space background with a generated particle starfield (8000+ stars).
   • Sun: PointLight + AmbientLight.
   • Planets: Create meshes for the Sun and 8 planets. Use reasonable relative scaling for visualization (not 1:1 astronomical scale, but visually pleasing).
   • Saturn's Rings: Create a ring geometry for Saturn with transparency.
   • Orbits: Draw thin line trajectories for each planet's orbit.
3. Data & Content (English):
   • Store planet data in an array: Name, Type, Color, Radius, Distance, Speed.
   • Include detailed stats: Diameter, Day Length, Year Length, Temperature.
   • Include a short, scientific description for each planet in English.
4. Animation & Interaction:
   • Orbit: Planets must revolve around the Sun at different speeds.
   • Rotation: Planets must rotate on their own axis.
   • Raycasting: Implement mouse hover/click detection on planets.
   • Cinematic Camera: When a planet is clicked (or selected via UI), use Tween.js to smoothly animate the camera position and controls.target to follow the moving planet (enter "Satellite View").
5. UI/UX (HUD Style):
   • Style: Futuristic, glass-morphism aesthetics (translucent dark backgrounds, blur filters, thin borders).
   • Navigation: A list of buttons on the left to select planets.
   • Info Panel: A detail panel on the right that slides in when a planet is selected, showing the stats and description.
   • Loader: A loading screen that says "Generating Textures..." while the Canvas textures are being created.

Code Structure:

• init(): Setup Scene, Camera, Renderer.
• TextureFactory: The logic for generating textures.
• createSolarSystem(): Loop through data and create meshes.
• animate(): The render loop handling rotation and Tween updates.
