Crate oxigdal_3d 

OxiGDAL 3D

3D visualization, point cloud processing, and terrain mesh support for OxiGDAL.

This crate provides comprehensive 3D geospatial data handling capabilities:

Features

• Point Clouds: LAS/LAZ, COPC (Cloud Optimized Point Cloud), EPT (Entwine Point Tiles)
• Mesh Formats: OBJ, glTF 2.0/GLB export with texture support
• Terrain: TIN (Triangulated Irregular Network), DEM to mesh conversion
• Visualization: 3D Tiles (Cesium) for web-based 3D mapping
• Classification: Ground, vegetation, building extraction

Example Usage

use oxigdal_3d::*;

// Read LAS point cloud
let mut las = pointcloud::LasReader::open("points.las")?;
let point_cloud = las.read_all()?;

// Classify ground points
let ground = classification::classify_ground(&point_cloud.points)?;

// Create TIN from ground points
let tin = terrain::create_tin(&ground)?;

// Export as glTF mesh
let mesh = terrain::tin_to_mesh(&tin)?;
mesh::export_gltf(&mesh, "terrain.glb")?;

Architecture

• Pure Rust implementation where possible
• Streaming support for large datasets
• Memory-efficient processing with spatial indexing
• Web-ready formats (glTF, 3D Tiles)
• Feature-gated C dependencies (PDAL, PCL) per COOLJAPAN Pure Rust Policy
