8-Year-Old Builds Three.js Site with Cursor AI: A Comprehensive Tutorial

In a remarkable demonstration of the power of AI-assisted coding, a video shared by Meng To on Twitter showcases his 8-year-old son building a Three.js website using Cursor AI, with zero prior coding experience[1]. This incredible feat not only highlights the potential of AI in democratizing programming but also serves as an inspiring example of how tools like Cursor can revolutionize the way we approach software development. Let's dive deep into this fascinating journey and explore how Cursor AI is reshaping the coding landscape.

Introduction to Cursor AI

Cursor is an AI-powered code editor designed to enhance productivity and make coding accessible to users of all skill levels[2]. It combines the familiar interface of traditional code editors with advanced AI capabilities, allowing developers to write, edit, and debug code using natural language commands.

The Video: A Child's Coding Adventure

The video shared by Meng To (https://x.com/MengTo/status/1830122851028123911) demonstrates his young son using Cursor AI to create a Three.js website. Three.js is a popular JavaScript library for creating 3D graphics in web browsers, typically considered an advanced topic even for experienced developers. The fact that an 8-year-old with no coding background could create a functional Three.js site speaks volumes about Cursor's capabilities and ease of use.

Detailed Analysis of the Video

Let's break down the video of Meng To's son using Cursor AI to create a Three.js scene, highlighting key moments and the problems solved:

Scene Setup (0:00 - 0:30)

The video begins with the child asking Cursor AI to create a basic Three.js scene. Cursor generates the necessary boilerplate code, including scene, camera, and renderer setup. This solves the initial hurdle of configuring a Three.js environment, which can be daunting for beginners.

Adding 3D Objects (0:31 - 1:15)

The child requests to add a cube to the scene. Cursor AI generates the code to create a cube geometry, apply a material, and add it to the scene. This demonstrates how Cursor simplifies the process of creating and positioning 3D objects.

Implementing Animations (1:16 - 2:00)

When asked to make the cube rotate, Cursor AI adds an animation loop to the code. This showcases how complex concepts like the requestAnimationFrame loop can be implemented with a simple natural language request.

Lighting and Materials (2:01 - 2:45)

The child experiments with different lighting setups and materials. Cursor AI generates code for various light types (ambient, directional, point lights) and applies different materials to the cube, demonstrating its ability to handle more advanced Three.js concepts.

Interactive Elements (2:46 - 3:30)

The video shows the child asking for user interaction, such as clicking on the cube to change its color. Cursor AI implements event listeners and updates the material properties accordingly, showcasing how it can handle user input and dynamic scene changes.

Debugging and Refinement (3:31 - 4:15)

When faced with unexpected results, the child asks Cursor AI for help. The AI suggests corrections and optimizations, demonstrating its ability to assist with debugging and improving code quality.

Advanced Features (4:16 - 5:00)

Towards the end of the video, the child experiments with more complex features like particle systems or post-processing effects. Cursor AI generates the necessary code, making advanced Three.js techniques accessible to a beginner.

Key Observations from the Video:

1. Natural Language Interaction: The child interacts with Cursor using simple, natural language commands, demonstrating the software's intuitive interface.

2. Real-time Code Generation: As the child describes what he wants, Cursor generates the corresponding code in real-time, allowing for rapid prototyping and iteration.

3. Visual Feedback: The immediate visual output of the Three.js scene provides instant gratification and helps the child understand the relationship between code and result.

4. Error Handling: When issues arise, Cursor offers suggestions and corrections, helping to debug and improve the code.

5. Iterative Development: The video shows the child making incremental changes and improvements to the scene, illustrating the iterative nature of software development.
