From Text to 3D Universe: Building a Solar System with Gemini Canvas

In a recent episode of AI Boost Bites, Google demonstrated how Gemini Canvas can turn a single sentence into a fully functional, interactive 3D model. Hosted by Ethan, the tutorial walks users through building a scientifically accurate simulation of the solar system—complete with educational features—without writing a single line of code yourself.

What is Gemini Canvas?

Gemini Canvas is a specialized workspace within Gemini designed for collaborative creation. Unlike the standard chat interface, Canvas provides a dedicated window for drafting documents or generating code, allowing users to preview, edit, and iterate on complex projects like web apps and visualizations in real-time.

Step-by-Step: Building the Simulation

The video outlines a simple three-step process to go from a blank page to a rotating 3D universe.

1. The Foundation Prompt

The process begins with a direct instruction. Ethan types a simple prompt into Gemini Canvas:

“Create a 3D simulation of the solar system”

In seconds, Gemini generates the code and renders a 3D environment where the user can drag to rotate the view and scroll to zoom in and out, inspecting the planets orbiting the sun.

2. Adding Interactivity

To transform the visual model into a functional tool, the tutorial demonstrates how to add controls using natural language. The user asks Gemini to:

“Add a button that lets me pause the planets orbiting the sun and let me then click on a planet to learn more”

Gemini instantly updates the code, adding a pause button that freezes the orbits, allowing for easier inspection of individual celestial bodies.

3. Gamifying the Learning

Finally, the tutorial turns the simulation into an interactive encyclopedia. By prompting Gemini to “add fun facts about the planets on the side of the screen when I hover my mouse over a planet,” the tool adds a dynamic UI layer. Now, clicking on Jupiter or Mars displays their size, nickname, and other trivia, effectively creating a custom educational app in minutes.

Why This Matters

This demo highlights a shift in how we create digital tools. As noted in the video, you no longer need to be a 3D artist or a developer to build immersive experiences. Whether for a classroom project or personal curiosity, your imagination is the only limit to what you can build.
