Convert b3d to x3d

What is the difference between .b3d and .x3d?

Description: B3D files are 3D models created with the Blitz3D game development engine. They store the model's geometry, textures, and shading information. B3D models can be used in games, 3D animation, and other 3D applications.; 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.
