What is meshoptimizer?

The meshoptimizer npm package is a library for optimizing 3D meshes. It provides various algorithms to reduce the size of 3D models, improve rendering performance, and optimize vertex and index buffers.

What are meshoptimizer's main functionalities?

Vertex Cache Optimization

This feature optimizes the order of indices to improve the vertex cache efficiency, which can lead to better rendering performance.

const meshopt = require('meshoptimizer');
const indices = new Uint32Array([0, 1, 2, 2, 3, 0]);
const optimizedIndices = meshopt.optimizeVertexCache(indices, 4);
console.log(optimizedIndices);

Overdraw Optimization

This feature reorders triangles to reduce overdraw, which can improve rendering performance by minimizing the number of pixels that are drawn multiple times.

const meshopt = require('meshoptimizer');
const indices = new Uint32Array([0, 1, 2, 2, 3, 0]);
const vertices = new Float32Array([0, 0, 0, 1, 0, 0, 1, 1, 0, 0, 1, 0]);
const optimizedIndices = meshopt.optimizeOverdraw(indices, vertices, 3, 1);
console.log(optimizedIndices);

Vertex Fetch Optimization

This feature reorders vertices to improve the efficiency of vertex fetch operations, which can lead to better performance in rendering pipelines.

const meshopt = require('meshoptimizer');
const indices = new Uint32Array([0, 1, 2, 2, 3, 0]);
const optimizedIndices = meshopt.optimizeVertexFetch(indices, 4);
console.log(optimizedIndices);

Index Buffer Compression

This feature compresses the index buffer to reduce the size of the 3D model, which can save memory and bandwidth.

const meshopt = require('meshoptimizer');
const indices = new Uint32Array([0, 1, 2, 2, 3, 0]);
const compressedIndices = meshopt.encodeIndexBuffer(indices, 4);
console.log(compressedIndices);

const meshopt = require('meshoptimizer');
const vertices = new Float32Array([0, 0, 0, 1, 0, 0, 1, 1, 0, 0, 1, 0]);
const compressedVertices = meshopt.encodeVertexBuffer(vertices, 3, 4);
console.log(compressedVertices);
