Three.js is a lightweight, open-source JavaScript library that simplifies the process of rendering 3D graphics in the browser using WebGL. It provides a high-level API for creating and manipulating 3D scenes, including cameras, lights, materials, and animations. Three.js is widely used for building interactive 3D web applications, games, data visualizations, and more.
Is There a Point to Learning Three.js with Tools Like Spline?
Absolutely! While tools like Spline (and others such as Verge3D, PlayCanvas, or Babylon.js) offer more user-friendly, no-code/low-code solutions for creating 3D web experiences, Three.js remains a powerful and versatile tool with unique advantages. Here’s why learning Three.js is still worth it:
Why Three.js is Still Relevant
- Full Control and Flexibility:
- Three.js gives you complete control over every aspect of your 3D scene. Unlike higher-level tools, you’re not limited by pre-built templates or workflows. If you can imagine it, you can build it with Three.js.
- This flexibility is crucial for custom projects that require unique interactions, complex animations, or advanced shaders.
- Performance Optimization:
- With Three.js, you can fine-tune performance for your specific use case. This is especially important for projects with high-poly models, real-time physics, or large datasets.
- Tools like Spline abstract away many performance considerations, which can be limiting for advanced users.
- Large Community and Ecosystem:
- Three.js has been around since 2010 and has a massive community of developers. This means extensive documentation, tutorials, and third-party libraries are available to help you solve almost any problem.
- The ecosystem around Three.js (e.g., libraries like Cannon.js for physics, Tween.js for animations) is vast and well-supported.
- Cost-Effective:
- Three.js is free and open-source, making it an excellent choice for indie developers, startups, or anyone on a budget. Many alternative tools require paid subscriptions for advanced features or commercial use.
- Learning WebGL Fundamentals:
- Learning Three.js gives you a deeper understanding of WebGL and 3D rendering principles. This knowledge is transferable to other tools and frameworks, making you a more versatile developer.
- Custom Integrations:
- Three.js can be easily integrated with other JavaScript frameworks (e.g., React, Vue, Angular) and backend systems. This makes it ideal for building complex web applications that require 3D visualization.
When to Use Tools Like Spline Instead
While Three.js is powerful, tools like Spline have their place:
- Rapid Prototyping: Spline allows you to create 3D scenes and interactions quickly without writing code.
- No-Code Workflows: If you’re a designer or non-developer, Spline’s visual interface is more accessible than writing JavaScript.
- Simple Projects: For basic 3D visualizations or configurators, Spline can save time and effort.
However, Spline and similar tools often lack the depth and customization options that Three.js provides. They may also come with licensing costs or limitations for commercial use.
Why Be Pro Three.js?
- Future-Proof Skills:
- Web-based 3D graphics are becoming increasingly important in industries like e-commerce, gaming, education, and AR/VR. Learning Three.js equips you with skills that are in high demand.
- Creative Freedom:
- With Three.js, you’re not constrained by the limitations of no-code tools. You can create unique, innovative experiences that stand out.
- Career Opportunities:
- Proficiency in Three.js is a valuable skill for front-end developers, game developers, and creative technologists. It opens doors to exciting projects and job opportunities.
- Open-Source Power:
- Being open-source, Three.js is constantly evolving with contributions from developers worldwide. You can even contribute to its development or customize it to suit your needs.
Conclusion
Yes, tools like Spline are fantastic for quick, no-code 3D projects, but they don’t replace the need for Three.js. Learning Three.js is still highly valuable if you want full control, flexibility, and the ability to build complex, high-performance 3D web applications. It’s a skill that will serve you well in the growing field of web-based 3D graphics.

Three.js is still a solid skill to have! No-code tools like Spline are super convenient, but they don’t give the same level of control or depth. If you really want to create something unique (or just understand how 3D on the web actually works), learning Three.js is totally worth it.
