v1.0.0

SplatTransform v1.0.0

We're excited to announce SplatTransform v1.0.0 - a major milestone that transforms the project from a CLI-only tool into a full-featured library with programmatic API support for both Node.js and browser environments.

Highlights

• Library API: SplatTransform can now be imported as a library in your JavaScript/TypeScript projects
• Cross-Platform: Works in both Node.js and browser environments
• Streaming File Systems: Flexible file system abstractions for reading from URLs, memory, or ZIP archives
• Statistical Summaries: New --summary action for data analysis

New Library API

import {
    readFile,
    writeFile,
    getInputFormat,
    getOutputFormat,
    DataTable,
    processDataTable,
    UrlReadFileSystem,
    MemoryFileSystem
} from '@playcanvas/splat-transform';

Key Exports

Export	Description
readFile / writeFile	Read and write splat data in various formats
DataTable, Column	Core data structures for splat data
processDataTable	Apply transformations, filters, and actions programmatically
computeSummary	Generate statistical summaries for data analysis
UrlReadFileSystem	Read from URLs (browser/Node.js)
MemoryReadFileSystem	Read from in-memory buffers
ZipReadFileSystem	Read from ZIP archives
MemoryFileSystem / ZipFileSystem	Write to memory or ZIP archives

New Features

• Statistical Summary Action (-m, --summary): Generate per-column statistics including min, max, median, mean, stdDev, nanCount, and infCount
• Configurable WASM URL: Browser bundlers can now configure the WebP WASM module location
• Improved K-Means Initialization: Better clustering for SOG compression

Breaking Changes

• PlayCanvas is now a peer dependency: Install playcanvas alongside @playcanvas/splat-transform
• Node.js Buffer removed: All internal code now uses Uint8Array for cross-platform compatibility

Installation

# CLI usage
npm install -g @playcanvas/splat-transform

# Library usage
npm install @playcanvas/splat-transform playcanvas
