Spline.design Introduction

Spline.design is a powerful, browser-based 3D design tool that's revolutionizing how game developers create 3D assets. Unlike traditional 3D software that requires complex installations and steep learning curves, Spline runs entirely in your web browser and offers an intuitive interface that makes 3D design accessible to everyone.

In this chapter, you'll learn what Spline is, why it's perfect for game development, and how to get started with your first project.

What is Spline?

Spline is a modern 3D design tool that combines the power of professional 3D software with the accessibility of web-based applications. It's designed for creators who want to build 3D content without the complexity of traditional tools like Blender or Maya.

<strong>Key Features:</strong>

  • <strong>Browser-based</strong> - No installation required, works on any device
  • <strong>Real-time collaboration</strong> - Multiple team members can work together
  • <strong>Interactive 3D</strong> - Create interactive 3D experiences, not just static models
  • <strong>Easy export</strong> - Export to popular formats for game engines
  • <strong>Intuitive interface</strong> - Designed for designers, not just 3D specialists

<strong>What Makes Spline Different:</strong>

Traditional 3D software focuses on modeling and rendering. Spline goes further by enabling interactive 3D experiences that can be embedded in websites, used in game engines, or exported as standalone applications.
