Renderer

• The renderer runs in world coordinates (B coordinate system), which uses plot positioning on standard data (std) to piece together the complete world.

Types of Renderer

• According to system requirements, the Septopus Engine supports three types of renderers, whose main functions are as follows:

Type	Main Function	Code
3D Renderer	主The main renderer displays the 3D scene of the Septopus world	/render/render_3d.js
2D Renderer	2D map renderer, showing a small map	/render/render_2d.js
Observe Renderer	Display models generated by other 3D software or single block	/render/render_observe.js

Program Structure

• Use the unified rendering entry RENDERER.show(), which can be called directly by the framework.

• Renderer needs to build the running Dom structure. For example, 2D needs to create <canvas></canvas> for drawing.

*renderer can parse standard data (std) to generate rendering data, or use data that has been parsed by other renderers for output.
