eorld-usdp 1.0.0

Eorld USDP SDK — Unified Space Description Protocol v1.0

Eorld USDP SDK

USDP (Unified Space Description Protocol) v1.0 — an open-source 3D spatial data protocol and developer toolkit.

Overview

The Eorld USDP SDK provides a unified 3D spatial description protocol. Any 3D reconstruction tool can implement a single Provider to convert its output into USDP format and enter the Eorld spatial ecosystem.

Components

Module	Description
USDP Protocol	Unified Space Description Protocol specification (v1.0)
P003 Coordinate Normalization	Multi-source coordinate system unification
Provider Interface	Abstract plugin interface for spatial data sources
Reference Implementation	COLMAP/SfM converter

Installation

pip install eorld-usdp

Quick Start

from usdp import SpaceDescription, CoordinateSystem
from usdp.provider import USDPProvider
from usdp.coordinate import normalize_coordinates

# Load any 3D reconstruction output
space = SpaceDescription.from_provider(MyProvider, source_path="scan/")

# Normalize to USDP standard coordinate system
space = normalize_coordinates(space, target=CoordinateSystem.USDP_STANDARD)

# Export to USDP format
space.export("output.usdp")
