# 3D Data Compression

### Smaller 3D assets, faster loading, seamless rendering.

**STD.DEV utilizes Draco compression to reduce 3D mesh and point cloud file sizes, enabling faster loading and lower bandwidth usage.** Because Draco requires specialized handling for web integration, the system employs WASM-based decompression to ensure efficient, high-performance real-time decoding across VR, AR, and browser-based platforms.

### Draco Geometry Encoding

The asset pipeline applies Draco compression algorithms to selectively collapse mesh and point cloud topologies. This mathematically reduces three-dimensional model sizes without sacrificing coordinate quality, enabling fluid real-time rendering logic and faster downloads.

### WebXR Bandwidth Standardization

Data payload limits are rigidly enforced for Extended Reality interfaces to deliver high-performance 3D spatial content. This strict compression minimizes bandwidth usage across platforms, eliminating pipeline bottlenecks in VR and AR environments with minimal performance trade-offs.

### WebAssembly Payload Decoding

To overcome web execution limitations, compressed topological data is decoded in real-time using compiled WebAssembly modules. This shifts processing off the main thread, allowing large-scale spatial assets to load at near-native CPU speeds with minimal latency.

**By integrating Draco compression, STD.DEV ensures that 3D content loads faster, consumes less bandwidth, and delivers high-quality rendering**—whether in web, VR, or AR environments.
