• Additional options for point cloud filtering, scaling, swapping y-z axis, splitting to smaller files and more
• Supports LAS 1.0 to 1.4
• RGB colors : read point cloud RGB colors
• Intensity or Classification color : read point cloud intensity/classification colors (only RGB or Intensity or Classification, not both at the same time currently)

Visit: https://las2gltf.kelobyte.fi *50% discount for existing Pointcloud Viewer & Tools users!

Quick Start

• Once you have installed the converter plugin, you can select GLB Export format
• 
• Select your LAZ source file (you can download sample file here: https://files.fm/u/658mgracwb )
• Set output folder
• Adjust settings, Recommended initial settings:
  • [ x ] Auto-Offset, to bring cloud near 0,0,0.
  • [ x ] Swap Y and Z (because Unity Y is Up)
  • [ x ] Invert X is often required for LAZ to GLB files, otherwise point cloud is mirrored in X axis
• For most clouds, you want [x] Split to grid is disabled, so that you get single file output
• Optional: You can now save your settings into File for later Use, press Export Settings
• Press Convert to begin processing
• If you enabled [x] Open output folder, Explorer window is opened (so you can access file easily)

Installation

• Download main Converter (if you don't already have it) https://github.com/unitycoder/PointCloudConverter/releases ) Important: Use release "106" or later!
• Download your GLB plugin (you'll receive serial code & download site link in your email after purchase), unzip it. *Download link: https://las2gltf.kelobyte.fi/download/
• Place unzipped files into "PointCloudConverterX64/plugins/" (if plugins folder doesn't exists, create it under pointcloudconverter folder)
• 
• You can browse that folder from this button in GUI:
• 

Using Commandline

• Check main converter commandline arguments: https://github.com/unitycoder/PointCloudConverter/wiki/Commandline-Arguments
• Or use GUI to setup correct settings and press "Get Arguments" (to get ready to use commandline args)
• Or run: pointcloudconverter.exe -? to get help output
• GLTF specific arguments are:
  • -exportformat=glb
  • -usegrid=true *if you want to split cloud(s) into multiple files

Limitations

• Really large files cannot be converted as single glb files (tested: 2.8gb laz file works, 3.8gb laz file doesn't work, need to use split to grid to output multiple files)

Troubleshooting

Conversion runs successfully, but there is not output

• Your LAZ file is probably too large. Use [x] Split to grid to output multiple files

My glb cloud is split into multiple files?

• Disable [ ] Use Grid (split to grid) option in converter

Support

• You can report or view open issues at https://github.com/unitycoder/PointCloudConverter/labels/GLTF%2FGLB (using GLTF label, if its specific to this plugin. Or see all issues, if issue is related to main converter)

FAQ

Does this work on Mac or Linux?

• No, it is Windows only

Does it have GUI or Commandline?

• Both, if you run exe without arguments, it opens the GUI.
