Convert mesh to x3d

What is the difference between .mesh and .x3d?

Description: Mesh is a 3D graphic data file type that contains information about the surface of a 3D object. It is composed of vertices, edges, and faces that define the shape and structure of the object. Mesh files can be used to create 3D models for computer graphics and animation.; X3D (Extensible 3D) is a royalty-free open standard file format used to represent 3D computer graphics. It is used to store and interchange 3D model data, including surface geometry, color, animation, and metadata. X3D files are built on the XML standard, and can be viewed and edited with a variety of 3D modeling programs.
