Cesium ion Updates

New assets are available for use in the Asset Depot! This includes:

  • A 10 billion point 3D Tileset point cloud of Montreal
  • 3D Tileset surface models of Cairo, Caracas, Damascus, Honolulu, San Francisco, and Tehran courtesy of Vricon

Improvements to the 3D tiling pipeline include:

  • Fixed a few point cloud bugs related to projections and ECEF input data
  • Improved SRS detection for CityGML files
  • Trimmed the amount of metadata stored in tiles from CityGML input

These updates are included in the hosted tilers on Cesium ion, and in the on-premise 3D Tiling Pipeline command line tools.

A ~10 billion point 3D Tileset of the city of Montreal, Canada captured in 2015 with a resolution of 20 cm. Tiled and hosted by Cesium ion.

CesiumJS 1.58 Release

Some highlights from the CesiumJS 1.58 release are:

  • Reduce the number of Bing transactions and ion Bing sessions used when destroying and recreating the same imagery layer to 1.
  • Fixed memory leak when removing entities that had a HeightReference of CLAMP_TO_GROUND or RELATIVE_TO_GROUND. This includes when removing a DataSource.
  • Fixed 3D Tiles credits not being shown in the data attribution box.

This month we’ve got our eye on Trendspek. They creates digital twins from drone imagery and shares them with 3D Tiles, making it possible to assess maintenance needs remotely.

Trendspek’s tools include measurements, annotations, and timeline viewers for comparing tilesets.
