Web Worker Performance

What are Web Workers?

Web Workers allow you to run scripts in background threads, separate from the main execution thread of a web application.

Benefits in Our Game

• Offloading Terrain Generation: Moves computationally intensive tasks off the main thread.
• Smoother Gameplay: Prevents terrain generation from causing frame rate drops.
• Responsive UI: Ensures the game remains interactive while generating new chunks.

Implementation Details

1. Chunk Generation:
   • Each chunk is generated in a separate web worker.
   • The main thread sends chunk coordinates to the worker.
   • The worker returns the generated chunk data.
2. Data Transfer:
   • Use transferable objects to efficiently pass large chunk data between the worker and main thread.
   • Example: postMessage(chunkData, [chunkData.buffer])
3. Worker Pool:
   • Implement a pool of workers to manage multiple chunk generations simultaneously.
   • Helps in utilizing multi-core processors effectively.

Texture Atlas Optimization

What is a Texture Atlas?

A texture atlas is a large image containing multiple smaller textures, used to reduce draw calls and improve rendering performance.

Benefits in Our Game

• Reduced Draw Calls: Minimizes GPU state changes.
