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.
It is one of the most important files in 3D printing and graphics programs. OBJ is a neutral interchange format for storage of non-animated 3D models.
