The Cesium team is delighted to be a part of your Christmas traditions with the NORAD Tracks Santa program! Built on the CesiumJS open-source 3D mapping library, the Santa Tracker gives everyone a look at Santa’s Christmas Eve journey, as children around the world nestle snug in their beds while...

We are happy to announce the release of Cesium 1.52. Highlights include: Added support for high dynamic range (HDR) rendering. It is enabled by default when supported, but can be disabled with Scene.highDynamicRange. #7017 Added functions to get the most detailed height of 3D Tiles on-screen or off-screen. #7115 Added...

We have a new showcase up on our demos page! Geology of Dorset The Dorset Geologists’ Association Group has built an interactive map with Cesium that allows users to layer many geology datasets to better understand the region around Dorset. The map fuses Digital Elevation Model over Europe (EU-DEM) and...

The 3D tiling pipeline on Cesium ion now includes support for interior and exterior BIM and CAD models, adding to existing support for point clouds, photogrammetry, and 3D buildings. BIM model with photogrammetry scene, courtesy of Bentley Systems. Bring geospatial context to your BIM and CAD 3D Tiles by combining...

This is a guest post by Pascal Poulain about some experimental work he did on embedding time series inside 3D Tiles. He uses weather prediction data to illustrate the concept. - Sarah When visualizing spatio-temporal datasets in CesiumJS, out-of-core processing, based on 3D Tiles, can offer better capacities in terms...

Visualizing and understanding massive 3D data often involves combining different formats into the same scene. 3D Tiles already enables this kind of data fusion. For greater flexibility, CesiumJS provides a classification system that allows you to dynamically highlight and annotate your 3D data using any arbitrary set of geometry. For...

We are happy to announce the release of Cesium 1.51. Highlights include: Added WMS-T (time) support in WebMapServiceImageryProvider. Added cutoutRectangle to ImageryLayer, which allows cutting out rectangular areas in imagery layers to reveal underlying imagery. Ground atmosphere, sky atmosphere, and fog colors now match. Shrunk minified and gzipped Cesium.js by...

One of the new visual improvements in CesiumJS 1.50 is the ground atmosphere. This can be seen on the globe when viewed from space. The new ground atmosphere on the far right makes the globe look more realistic. CesiumJS already includes a sky atmosphere, which allows you to control the...

With the 1.50 release, CesiumJS now supports the new specular glossiness glTF extension. This extension gives you greater control over how a 3D model responds to various realistic lighting conditions. Materials on this model are powered by the new specular-glosssiness extension.
