Description
The X3D file format was introduced in 2002 as a successor to the 3D VRML (WRL) file format. X3D files contain 3D mesh and model information defined using vertices, faces, normals, and material data, making them broadly as capable as the older VRML format.
X3D files are structured XML text-based files that allow full 3D scenes to contain models comprised of 3D mesh data and other simple shapes. There are browser extensions that allow X3D files to be directly embedded within HTML to allow rendering directly to a web page; however, the format has not seen widespread adoption.
X3D Notes
If your X3D file contains textures, these will be ignored. If a material contains color information, this will be translated where possible.
Supported Features
- Mesh geometry
- Mesh material colors
- Vertex colors
Unsupported Features
Description
The VTK file format is a 3D modeling and graphics format supported by the Visualization Toolkit. Created in the '90s, the Visualization Toolkit provides a series of data and visual tools for advanced 3D modeling applications. Some example functions of the toolkit include polygon simplification, mesh repair and smoothing, and more.
The format has evolved over the years. It started out as a simple text-based format that could be edited within a simple text editor. Additional features have been added over the years, with the most recent version of the format supporting an XML-based format.
VTK Notes
Any model converted to the VTK format will be stored in a triangulated mesh format.
Supported Features
- Polygon mesh
- Triangle strip-base mesh
