Point Clouds to 3D tiles

Hi there,

Firstly, thank you and very interesting project!

I am quite new to this, but I would like to know, how to convert .las or .pod to 3D tiles? Is there a converter available? Or if not, what would be the best way to include point clouds to Cesium?

Thank you,

Monika

Hi Monika,

For 3D Tiles, we are actively working on the point cloud tile format, see https://github.com/AnalyticalGraphicsInc/3d-tiles/issues/22#issuecomment-231618325

I’m not aware of any tools for converting LAS files yet, but this will be one of the services in the upcoming https://cesiumjs.com/

Also, for the latest news on 3D Tiles, watch this thread: https://groups.google.com/forum/#!topic/cesium-dev/tCCooBxpZFU

Hi Monika,

This project may help you convert LAS files to cesium point cloud tiles:

I've been looking at the PCD specs. Why invent another new point cloud data format? Have you considered simply using one of the widely used data formats that is currently available? E.g. the open source .pcd format (http://pointclouds.org/documentation/tutorials/pcd_file_format.php#pcd-file-format)

Cheers

Hi Nahid,

PCD is a general-purpose format; the 3D Tiles point cloud tile format is optimized for 3D rendering. For example, this is similar to the different between COLLADA and glTF for general 3D models, and the different between PSD and png for images.
