Converts LandXML files, versions 2.0 and 1.2, to .glTF files for 3D viewing integration. This project is setup using CMake for Windows, Linux and MacOS.

Prebuilt Windows installer available at: https://buymeacoffee.com/nathancrews/e/255640

Example: Open Windows Powershell, VSCode terminal or any other terminal that can run cmake, then:

c:\>d:

d:\>CD GitHub\LandXML2glTF

d:\GitHub\LandXML2glTF>mkdir build

d:\GitHub\LandXML2glTF>CD build

[Windows and Linux]

d:\GitHub\LandXML2glTF\build>cmake ..

[MacOS]

d:\GitHub\LandXML2glTF\build>cmake -G Xcode ..

Assuming no errors, when cmake completes, the \build\LandXML2GLTF.xxx (or Makefile) project files should exist.

CMake build for Windows, MacOs and Linux:

d:\GitHub\LandXML2glTF\build>cmake --build .

Required: [path to LandXML file] full or relative path to the LandXML file(s). If the path contains a trailing wild char ".\LandXML\*", all .xml files in that directory will be converted.

Optional: /s If specified sub-directories will be searched for .xml for conversion. /b If specified valid LandXML .xml files will be converted to .glb files.

Example Usage 1:

.LXML2glTF.exe "..\..\..\..\LandXML\subdivision-2.0.xml"

Output: Converting "..\..\..\..\LandXML\subdivision-2.0\subdivision-2.0.xml" to "D:\GitHub\LandXML2glTF\LandXML\subdivision-2.0\subdivision-2.0.gltf" Parsing and building LandXML model... Building glTF model... Writing glTF file: D:\GitHub\LandXML2glTF\LandXML\subdivision-2.0\subdivision-2.0.gltf

Example Usage 2:

D:\github\landxml2gltf>.\Release\LXML2glTF.exe ".\LandXML\*" /s /b

The GDAL (PROJ) library is used for WGS84 geolocation and requires evironment variable PROJ_LIB pointing to the location for the requird proj.db file. A proj.db file is provided in the \LXML2glTF\data directory.

Example: PROJ_LIB="D:\GitHub\LandXML2glTF\LXML2glTF\data"
