The STL, or Standard Triangle Language, file format has been around since the '80s and is supported by most modern 3D modelling applications. In particular, the STL format has become something of a standard format within the area of 3D printing, despite the rise of more modern formats such as 3MF.

STL files come in two flavours: binary or text format. The text format is human-readable, making it easy to perform manual edits, but can lead to very large file sizes. As you can imagine, the binary format is much more compact and represents the majority of the STL files you are likely to encounter.

The format itself is very simple; the 3D model is represented by a sequential list of triangles, with each triangle defined with 3 points consisting of their X, Y, and Z positions, along with an additional vector that contains the face normal (the direction the face is pointing). There is an additional attribute block for each triangle; however, this is largely unused and thus unsupported.

When converting 3D Model/Mesh files using our STL converter we will attempt to convert color materials into a suitable format for use in the converted file.

X3D (Extensible 3D) is an XML-based file format designed for representing and storing three-dimensional (3D) computer graphics and multimedia content. It is an evolution of the VRML (Virtual Reality Modeling Language) format, offering enhanced capabilities and extensibility. X3D files allow the creation of complex 3D scenes, models, and interactive environments that can be rendered and displayed in various applications, including web browsers with X3D plugins or dedicated 3D visualization software.

The X3D file format supports a wide range of 3D geometries, textures, lighting, animations, and interactions. It uses XML syntax, which makes it human-readable and easily parsed by computers. The extensible nature of X3D allows developers to define custom nodes and add new features, making it adaptable to evolving 3D graphics technologies and application requirements. Additionally, X3D files can be compressed to reduce file size and support faster data transmission over networks, making them suitable for web-based 3D applications and virtual reality experiences.

One of the key advantages of X3D is its platform-independence and interoperability. X3D files can be used across different operating systems and devices without the need for platform-specific modifications. They enable content creators and developers to share 3D assets seamlessly and ensure consistent rendering across various platforms. As a result, X3D has become a popular choice for applications involving 3D visualization, virtual reality simulations, computer-aided design (CAD), educational content, and other multimedia experiences that require dynamic and interactive 3D content.

X3D Converter Capabilities

When converting your STL to X3D our tool will attempt to accurately convert any color/material information.

Information for converting from STL to X3D

Your STL file will be converted to a X3D file using our unified 3D model and mesh conversion tool. Our STL 3D tool performs accurate conversions of 3D elements such as vertices, faces, normals and relevant material information. As both STL and X3D support color material information our tool will also attempt to convert the color information too.
