Introduction

This documentation covers the key components and optimizations implemented in our voxel game engine using Three.js. The engine focuses on efficient terrain generation, chunk management, and rendering techniques to create a performant and scalable voxel world.

Texture Management

THREE.TextureLoader()

We use THREE.TextureLoader() to efficiently load and manage textures for our voxel blocks.

const textureLoader = new THREE.TextureLoader();

const blockTextures = {
    grass: {
        top: textureLoader.load('./texture-pack/grass-top.png'),
        bottom: textureLoader.load('./texture-pack/dirt.webp'),
        side: textureLoader.load('./texture-pack/grass-side.webp')
    },
    dirt: textureLoader.load('./texture-pack/dirt.webp'),
    stone: textureLoader.load('./texture-pack/stone.webp'),
    // ... other textures ...
};

Best Practices

• Preload textures during the game's initial loading phase to avoid runtime delays.
• Use WebP format for textures when possible, as it offers better compression and faster loading times.
• Implement texture atlases for further optimization if the number of unique textures becomes large.

Mesh Optimization

Instanced Meshes

We use THREE.InstancedMesh for rendering multiple instances of the same geometry with different transformations, significantly reducing draw calls and improving performance.
