I ported the Point Cloud Library (PCL) to the browser!

import PCL from 'pcl.js'; async function main() { const pcl = await PCL.init({ url: 'https://cdn.jsdelivr.net/npm/pcl.js/dist/pcl-core.wasm', }); // Write a PCD file pcl.fs.writeFile('/test.pcd', ArrayBuffer); // Load PCD file, return point cloud object const pointCloud = pcl.io.loadPCDFile('/test.pcd'); // Filtering a PointCloud using a PassThrough filter, see: https://pcl.readthedocs.io/projects/tutorials/en/master/passthrough.html#passthrough const pass = new pcl.filters.PassThrough(); pass.setInputCloud(pointCloud); pass.setFilterFieldName('z'); pass.setFilterLimits(0.0, 1.0); pass.filter(pointCloud); // Save filtered point cloud objects as PCD files pcl.io.savePCDFileASCII('/test-filtered.pcd', pointCloud); // Read PCD file content, the content is ArrayBuffer const pcd = pcl.fs.readFile('/test-filtered.pcd'); // Delete all PCD files pcl.fs.unlink('/test.pcd') pcl.fs.unlink('/test-filtered.pcd') // ... } main();
