3D Object Protocol

• Septopus uses three.js as its rendering engine. In order to facilitate the separation of the Septopus Engine and the extension that can provide multi-rendering engine rendering, the call to three.js is encapsulated into this library.

• three.js is a complex 3D rendering engine with a large amount of code, which is split into another file in the three library.

Library Reference

• The encapsulated entry file is entry.js, which is introduced as a single file.

• There are only two methods to request this library, namely get and mesh, and their functions are shown in the following table.

Method	Function	Target
get	Get the built-in objects of three.js	All 3D components
mesh	Generate a mesh for rendering and put it into the scene for 3D display	Geometry and Materials

Object Category

• After organizing three.js, the following categories of objects and methods will be referenced

Category	Main Function	File location
Basic Componet	The foundation and core objects of 3D rendering environment construction, such as scenes, cameras, meshes, etc.	THREE_FOLDER/basic
Geometry	Creating geometric objects for 3D content	THREE_FOLDER/geometry
Light	Different lighting effects for basic lighting and creating atmosphere	THREE_FOLDER/light
Material	Give different materials to geometry to create rich and colorful 3D content	THREE_FOLDER/material
Texture	Parse the image and use it as the texture of the material	THREE_FOLDER/texture
Loader	Load models created by different types of external 3D software	THREE_FOLDER/loader
Extend	Secondary packaging components	THREE_FOLDER/extend
