One format for reality capture.
OPX is an open, spatially indexed and cloud-ready container for point clouds, imagery, GIS vectors, survey data, grids, metadata and future 3D Gaussian Splatting workflows.
Reality capture has outgrown single-purpose formats.
OPX is designed to bring the complete capture context into one coherent architecture: scan data, imagery, georeferencing, vectors, survey control and future neural representations.
Unified container
Store point clouds, images, vectors, survey data, grids, metadata and extension blocks in a single versioned file.
Native processing
OPX is built for spatial queries, tiling, LOD, lazy loading and application-native processing — not just exchange.
Future-ready
The block model supports unknown optional block preservation and future representations such as 3D Gaussian Splatting.
Clear structure, independent blocks, spatial access.
The OPX container starts with a Superblock and Root Directory. Every payload is a typed block with explicit versioning, alignment, validation and compatibility rules.
Developer preview foundation.
The current OPX 0.2.0-dev snapshot is an interoperability-focused development state. The reference implementation includes the core container, SDK, CLI tooling, LAS import/export workflows and an optional PDAL integration skeleton.
