What is navara_wasm?

navara_wasm is a module that compiles a Rust-based GIS engine into WebAssembly (WASM), enabling it to run in web browsers. It performs high-speed map processing while communicating asynchronously with the rendering engine.

Key Roles

• Serves as the entry point for running the Rust-based GIS engine in the browser
• Manages asynchronous communication with rendering engines (e.g., navara_three)
• Internally executes GIS processing such as LOD, coordinate transformation, and tile management
• Manages and updates internal state using Bevy ECS

Characteristics

• Rust-based engine

  • Achieves robust implementation through type safety
  • Optimized through low-level memory management

• Efficient integration with rendering engines

  • Receives commands from navara_three and others via event-driven architecture, processing state updates and feature additions asynchronously
  • Delegates heavy processing to Web Workers to reduce main thread load

• Efficient state management via ECS

  • Uses Bevy ECS to flexibly control entities (features, cameras, terrain, etc.)
  • Enables automatic control of LOD and visible range based on GIS data

• Rendering engine-agnostic architecture

  • Independent of specific rendering engines (Three.js, Babylon.js, etc.), providing high versatility
  • GIS engine API can be used independently

• Multi-platform support

  • Architecture enables future deployment beyond the web (native apps, mobile, etc.)

Typical Usage

It is executed internally through rendering engine libraries such as navara_three.
