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.

A WRL file, also known as a Virtual Reality Modeling Language (VRML) file, is a plain text file format used to represent 3D models and scenes for virtual reality applications. Developed in the mid-1990s, WRL files are utilized to describe the geometry, appearance, and interactions of objects within a virtual environment. These files contain a structured set of nodes that define various components, such as shapes, materials, transformations, and viewpoints, which collectively create a coherent 3D scene. WRL files were popular for web-based virtual reality experiences in the early days of the internet and played a crucial role in the development of interactive 3D content for online applications.

Each node in a WRL file represents a specific element of the 3D scene and includes attributes that define its characteristics. For instance, nodes can specify the shape of an object (e.g., cubes, spheres, or complex meshes), its position and orientation in the virtual space, its visual appearance through materials and textures, and even its behavior through animations or interactive features. The flexibility and extensibility of the VRML language allowed for the creation of diverse and immersive virtual reality experiences that could be accessed through compatible web browsers or specialized VRML viewers.

Although WRL files were widely used in the past, they have largely been replaced by more modern 3D file formats like OBJ (Wavefront Object) or glTF (GL Transmission Format). These newer formats offer better performance, compression, and support for advanced features, making them more suitable for contemporary virtual reality and 3D applications. Nonetheless, WRL files still hold historical significance as a pioneering standard that contributed to the early exploration and adoption of 3D content on the web and laid the groundwork for the evolution of virtual reality technologies.

WRL Converter Capabilities

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

Information for converting from STL to WRL

Your STL file will be converted to a WRL 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 WRL support color material information our tool will also attempt to convert the color information too.
