In the last chapter, you learned that 3D objects, called meshes, are composed of a list of 3D points (vertex buffer) and indices (index buffer) that creates the triangles that are drawn on the screen. To create complex meshes such as characters or buildings, 3D artists use modeling software that is capable of handling the vertex buffers and index buffers for us, including a lot of powerful tools for an easy creation.
The Babylon.js solution comes with plugins for Blender (https://www.blender.org/) and 3ds Max (http://www.autodesk.fr/products/3ds-max/overview), two famous modelers known by artists. These plugins are intended for 3D artists and are used to export the scenes built in these modelers to a format that Babylon.js is capable of loading. The exported files are JSON files with the .babylon
extension. More information about the format can be found at http://doc.babylonjs.com/generals/File_Format_Map_(.babylon...
