Cesium for Omniverse v0.24.0

Cesium for Unity Samples v1.13.1

CesiumJS 1.123

Cesium for Unreal

In October, we discussed our collaborations with Esri, highlighted AERO AI’s work on reintegrating WebODM with Cesium ion, shared progress on the Cesium Revit Add-In, introduced Japan Regional Terrain and updates to Japan 3D Buildings, dove into how to become a Cesium Certified Developer in Japanese, and explained key updates to glTF rendering in CesiumJS.

We made improvements across Cesium this month. To get notifications about our monthly releases, you can subscribe to the Cesium release roundup thread on our community forum.

CesiumJS 1.123 is now available. Highlights of the release include:

Updated default 3D Tiles and Model lighting when using PBR in order to create a more realistic appearance. #12129

Added ScreenSpaceCameraController.maximumTiltAngle to limit how much the camera can tilt. #12169 by new contributor albek446

Updated Japan Buildings sandcastle to use Japan Regional Terrain. #12259

Moved Viewer functionality to CesiumWidget to increase usability. Makes the CesiumWidget closer to a drop in replacement for the Viewer when not utilizing the extra Viewer widgets. #11967.

Fixed flickering issue caused by bounding sphere retrieval being blocked by the bounding sphere of another entity. #12230

Updates to default 3D Tiles and Model lighting when using PBR create a more realistic appearance.

Cesium for Unreal v2.10.0 is now available. Highlights of the release include:

Added a shared assets system that ensures external images referenced by different glTFs will only be loaded once per image. Previously, these images would be loaded again for each glTF that referenced them. This significantly reduces memory usage for tilesets that reuse the same textures.

Added CircumscribedGroundHeight property to CesiumSunSky. It defaults to 0, which is consistent with the previous behavior. It can be set to a larger value (like 40) to avoid dark splotchy artifacts when zoomed out far from the globe in certain tilesets where geometry extends very far beyond the ellipsoid in the low-detail representation, such as Google Photorealistic 3D Tiles.

Fixed a bug that caused incorrect lighting for tilesets using KHR_materials_unlit.

Reduced the memory used by tiles with KHR_materials_unlit.

CesiumGlobeAnchor properties are no longer shown on the main CesiumSunSky Details panel, because it is almost never necessary to set these. They can still be set on the component's own Details panel if needed.

Fixed error messages in the Unreal log about uninitialized fields in FCesiumSampleHeightResult.

CesiumJS 1.122 is now available. Highlights of the release include:

Added CallbackPositionProperty to allow lazy entity position evaluation. #12170 by new contributor jfayot

Added enableVerticalExaggeration option to models. Set this value to false to prevent model exaggeration when Scene.verticalExaggeration is set to a value other than 1.0. #12141 by new contributor timeichfeld-msa

Fix Texture errors when using a HTMLVideoElement. #12219

Fixed noise in ambient occlusion post process. #12201

The new CallbackPositionProperty allows Entities to lazily evaluate a position. Here, it’s used to track a drone flying through the Grand Canyon, as visualized using Google Photorealistic 3D Tiles.

Cesium for Unreal v2.9.0 is now available. Highlights of the release include:

Added SampleHeightMostDetailed function to Cesium3DTileset, which asynchronously queries the height of a tileset at a list of positions. It is callable from both C++ and Blueprints.

Drastically reduced tile mesh memory usage in UE 5.3 and 5.4 by working around a bug that causes those engine versions to add more texture coordinate sets than necessary.

Fixed a bug where the scale, noData, and default values of a property in EXT_strutural_metadata were not correctly passed to the tileset's material.

Trees and rocks floating above Cesium World Terrain, with lines drawn to where they would fall on the hills below them.

The same trees and rocks placed on the terrain using SampleTerrainMostDetailed. Assets provided by Quixel Megascans.

Pennoni is moving engineering from graph paper to streaming 3D models with Cesium for Unreal and Google Photorealistic 3D Tiles. Pennoni’s engineers, with collaborating architects, create 3D models for proposed structures using CAD data, point clouds, or photogrammetry. Pennoni loads these directly into Unreal Engine, ensuring accurate placement and lighting with Cesium for Unreal, and streams Google Photorealistic 3D Tiles via Cesium ion for real-world urban context, so the future view is clear.

As AEC projects increasingly require public input and organizations prefer plans with realism for their own understanding, Pennoni is moving engineering from graph paper to streaming 3D models with Cesium for Unreal and Google Photorealistic 3D Tiles.

Multidisciplinary engineering firm Pennoni—also our neighbor, headquartered in Philadelphia—serves clients across the US and has recently created immersive visualizations for clients in Florida; Virginia; Washington, DC; Maryland; Delaware; Pennsylvania; New Jersey; and Massachusetts. Whether it’s for a revamped playground, a shared-use path, a new neighborhood, bridge replacement, or a streetscape, Pennoni is bringing 3D interactions to architecture, engineering, and construction (AEC) planning and approvals. For example, Pennoni recently completed a digital twin of the new “dolphin” cylinder protection system for the Delaware River and Bay Authority (DRBA)’s Delaware Memorial Bridge, a critical twin suspension bridge crossing the Delaware River.

The firm has been heavily involved with design visualization and the creation of digital twins for engineering projects since 2015. That’s when Pennoni in-house viz duo Joe Spadea, PE, associate vice president, Pennoni FX Studios (PFX) visualization practice leader, and Steven Lewis, senior engineering technician, led the formation and creation of the PFX team. Since that time, there have been new faces and technologies to grow the firm’s capabilities. The firm began using Cesium in 2023, when Mike Sulesky, design visualization specialist at Pennoni, met the Cesium team at a Drexel University event. The PFX Studios team found that integrating Cesium with tools they were already using was easier and saved time, freeing up days of work to improve other facets of a project. With Cesium for Unreal and Google Photorealistic 3D Tiles, they no longer needed to hand-model a project’s surroundings and could instead create suitable scenes and infrastructure massing in house.

“It’s a constant balance of quality, budget, and time. Cesium allows us some flexibility of budget and time,” said Tim Timmons, senior design visualization specialist at Pennoni.

Pennoni creates interior and exterior 3D renderings and animations for its clients’ individual projects. For interiors, the firm’s Unreal Engine artists combine manual modeling with marketplace assets. For exteriors, Pennoni’s engineers, with collaborating architects, create 3D models for proposed structures using CAD data, point clouds, or photogrammetry. Pennoni loads these directly into Unreal Engine, ensuring accurate placement and lighting with Cesium for Unreal, and streams Google Photorealistic 3D Tiles via Cesium ion for real-world urban context, so the future view is clear. 

Google Maps Platform’s Photorealistic 3D Tiles were designed to scale from city blocks to citywide, immersing users in the surroundings they expect to see. Photorealistic 3D Tiles use the Open Geospatial Consortium (OGC) community standard 3D Tiles format. This format, created by Cesium, efficiently streams massive amounts of data required to display details for both collaborative planning and public awareness.

Pennoni reports that including Cesium in its digital innovation has helped the firm impress clients, win work, and market Pennoni itself, as the engineers work hand in hand with the company’s corporate communications team.

“Rather than waiting years for a project to be completed, and then capture and post photos, we can show visualizations immediately, in present day,” explained Spadea.

Earlier this month, Cesium announced we joined Bentley Systems, a leading infrastructure engineering software company, via acquisition. Together with Bentley, Cesium provides a complete platform for building digital twin experiences for the natural and built environment, with a strong commitment to open source, open standards, and open APIs.

"The recent acquisition is a great fit and a win for everyone. Pennoni has utilized Bentley tools and has a long-standing partnership with Bentley, so this is a welcome next step for us. It's remarkable as well that all three firms are headquartered in the Delaware Valley. Move over, Silicon Valley,” said Spadea.

In August, we explained more about the Cesium Certified Developer process, highlighted Cesium ion Self-Hosted updates, shed light on Cesium ion architecture (parts 1 and 2), launched Cesium Moon Terrain, did a deep dive into our GitHub Actions workflow, explored 3D models of early civilizations with UNICiv, and shared our SIGGRAPH trip report.

Add Cesium Moon Terrain to your Asset Library from the Cesium ion Asset Depot.

CesiumJS 1.121 is now available. Highlights of the release include:

Enable MSAA by default with 4 samples. This smooths jagged edges for increased visual realism. #12158

Switched the default (non-HDR) tonemapping for models, atmosphere, and globe from ACES to PBR Neutral Tonemap from Khronos. This widens the gamut of possible colors and provides more consistent color appearances across renderers. #12160

Expose the tonemapper and exposure properties of PostProcessStageCollection to allow changing the tonemap used when HDR is turned on. This defaults to the PBR Neutral Tonemap from Khronos. #12160

Added WaterMask globe material, which visualizes areas of water or land based on the terrain's water mask. #12149

Fixed several bugs with PBR lighting for more realistic rendering. #12100, #12116, and #12118

Cesium for Unreal v2.8.0 is now available. Highlights of the release include:

Added universal (Intel and Apple Silicon) binaries for Unreal Engine 5.2. Unreal Engine 5.3 and 5.4 already had universal binaries.

Raster overlays now have bAllowAnyoneToDestroyMe set to true by default. This allows them to be dynamically removed and destroyed at runtime via the Blueprint Destroy Component function called from anywhere, including Level Blueprints. Previously, attempting to delete a raster overlay from outside the Actor would result in an error.

Fixed a bug introduced in the previous release that caused instanced tilesets to render incorrectly.

Debug sections are no longer compressed on Linux and Android, improving compatibility.

Fixed a bug where calling Refresh on a CesiumRasterOverlay would cause the overlay to appear on the Cesium3DTileset, even if inactive.

Cesium for Unity v1.12.0 is now available. Highlights of this release include:

Editor and Player builds both now require macOS 10.15+. Previously, 10.13 was supported for Players, and 12.7+ was required for the Editor.

Added originPlacement property to CesiumGeoreference to toggle between "Cartographic Origin" and "True Origin" reference modes. Whereas "Cartographic Origin" is the default for georeferenced tilesets, "True Origin" may be used for non-georeferenced tilesets centered at the origin.

Fixed a bug that prevented using the Token panel with a new Cesium ion Server that had never had its token set before.

Fixed a bug that could cause a crash in CesiumIonSession when the object was garbage collected or the AppDomain was unloaded while network requests were in progress.

Fixed a bug that could cause CesiumFlyToController to unexpectedly interrupt a flight.

Fixed a bug that prevented clipping with CesiumCartographicPolygon from working with HDRP.

Cesium for Omniverse v0.22.0 is available. 

The extension now supports using non-WGS84 ellipsoids. A CesiumEllipsoidPrim should be specified on the ellipsoidBinding field of a CesiumReferencePrim.

Yesterday we announced a new Design Tiler and Revit Add-In, available for early access and feedback via our AECO Tech Preview Program. These tools transform IFC and Revit files into 3D Tiles. Read more here.

Globe view of UNICiv, showing sites from 1800 BCE - 1500 CE. The Legananny Dolmen in Ireland is selected.

Interactive digital maps display detailed contemporary geographic information, increasingly in 3D, for navigation, exploration, and virtual travel. What the world looked like near the beginnings of human civilization, however, is more difficult to discover, search, and visualize. Cesium Research’s most recent publication, UNICiv: A Universal Navigation Interface to Civilization, explores Cesium’s ability to support 3D models of ancient and historic sites within their geographical and temporal context.

Developed over the summer by Cesium's Yuhan Liu and led by Dr. Norman Badler, Head of Research, UNICiv is an extensible, universal, spatio-temporal interface that leverages Cesium for Unreal and 3D Tiles to visualize structures of the distant past. As a demonstration and education tool, UNICiv’s applications range from cultural heritage to urban planning. The UNICiv publication has been accepted as a full research paper to the Eurographics Workshop on Graphics and Cultural Heritage (GCH 2024). 

GCH is the premier technical meeting for novel digital technologies in the cultural heritage domain, fostering discussions in AI, Computer Graphics, Computer Vision, and Human-Computer Interaction.

UNICiv offers over 30 explorable 3D models of historic and archaeological sites around the world, displayed collectively on a single interactive globe. These models are produced by archaeologists, independent artists, or research projects from institutions and nonprofits. Sites range in time from 8000 BCE to 1500 CE. Examples include Neolithic monuments like Stonehenge, ruins of Bronze Age villages, and Greco-Roman temples. These models have been curated and imported into Cesium for Unreal through Cesium’s integration with Sketchfab. The models are imported into Unreal using Cesium’s plugin and placed on top of Cesium World Terrain with Bing Maps Aerial imagery.

Users can explore the past in 3D using UNICiv’s interface. Start by navigating a Cesium globe where ancient structures are highlighted as pins. The timeline interface indexes sites that appear on the globe. When users select a site, they are taken on a flight path to its geolocated model, where they can use traditional game controls to explore. Users can build their personalized list of sites to save, compare, and present their findings. Additionally, some locations offer reconstructed visualizations that can be overlaid on current-day ruins, providing a unique perspective on how these ancient sites once appeared.

From incorporating more models to iterating on user experience, UNICiv is an ongoing research project with exciting directions for future work. A significant task for the future would be to incorporate and reverse-engineer significant geographical changes to experience the natural environment experienced by the earth’s earliest inhabitants. In the meantime, UNICiv provides a uniform, 3D geospatial, contextualized interface to the re-discovered past.

The UNICiv publication was one of eight full research papers accepted to the 22nd Eurographics Workshop on Graphics and Cultural Heritage 2024. The Cesium research team is excited to present at the conference, which takes place September 16–18, 2024, in Darmstadt, Germany.

UNICiv is a powerful tool for visualizing temporal change on a global scale, especially in cultural and historical preservation. Initial user evaluations have highlighted UNICiv’s significant potential for advancing archaeological demonstration, education, and exploration. Furthermore, the UNICiv interface becomes increasingly adept at capturing the development of human civilization as more 3D models are integrated into it. Thus, the Cesium research team plans to soon provide open access to the UNICiv resource and welcomes collaborations and user contributions. Contact Dr. Norm Badler to express your interest in UNICiv.

Cesium Moon Terrain

“We launched Cesium Moon Terrain as an accurate and interoperable 3D Tiles canvas to support the international interest in lunar exploration and building structures on the moon's surface,” said Cesium CEO Patrick Cozzi. “Cesium Moon Terrain will enable engineers, system integrators, and digital content creators to build simulations, mission plans, and real-time operations experiences.”

Cesium Moon Terrain visualized in Cesium for Unreal

Cesium Moon Terrain was recently demonstrated at the Digital Twin for Lunar Development Workshop held at NASA’s Jet Propulsion Laboratory. The workshop brought the space enterprise community together to focus on advancing digital twins for NASA and the creation of an open, interoperable platform for a lunar digital ecosystem.

As early adopters, Ansys has utilized 3D Tiles in both their Systems Tool Kit (STK) and their RF Channel Modeler software to help users easily incorporate geospatially accurate datasets into their digital mission modeling and systems modeling engineering capabilities. Users are able to directly understand impacts of terrain in challenging locations such as lunar polar regions to accurately analyze communications system designs.

Another early adopter, Buendea, is collaborating with the NASA Advanced Operations Concept Lab on developing the XR Operations Support System (XOSS) to support real-time simulations on the Moon and Mars. Buendea is interested in Cesium Moon Terrain for its potential to enhance their ongoing projects.


“We’re excited about the potential of Cesium Moon Terrain to accelerate our work, including our efforts with NASA, to accurately plan and simulate explorations of the lunar surface,” said Julian Reyes, Founder of Buendea.

To access Cesium Moon Terrain, sign up for an account, or sign in to Cesium ion and add the tileset to your Asset Library from the Cesium ion Asset Depot. Once added, create a Cesium Story, incorporate the data into a web application with CesiumJS, or build advanced visualizations with Cesium for Unreal and Cesium for Unity.

Each of these visualization engines have been updated to enable non-WGS84 based ellipsoids to support an accurate representation of the lunar surface for analysis and measurements. Cesium Moon Terrain is also available for Cesium ion Self-Hosted. 

With Cesium Moon Terrain, users can leverage the same workflows and functionality already available in our open source runtime engines. Use Cesium Moon Terrain as a base layer to place models of habitats, vehicles, or rovers on the lunar surface.  If you have your own high resolution terrain data, clip and inset it within Cesium Moon Terrain so that your projects can live within a single continuous 3D surface rather than multiple separate project areas. 

NASA's ambitious Artemis program aims to return humans to the Moon and eventually land them on Mars. With this, along with initiatives from SpaceX, Boeing, BlueOrigin and others, the demand for an open, interoperable, standards-based platform has never been greater. Cesium Moon Terrain meets this demand, providing a versatile foundation for countless applications.

We look forward to seeing your projects built with Cesium Moon Terrain! Sign up or sign in to get started.

In July, we opened applications for this quarter’s Cesium Ecosystem Grants, welcomed new teammates, and attended SIGGRAPH 2024.

The Games are currently running through August 11, 2024, with 45 events at venues across Paris, in other regions of France, and nearly 10,000 miles away—including beach volleyball at Eiffel Tower Stadium, football (soccer for those of us in the US) in Nice, and surfing in Tahiti. Massive amounts of data are required to quickly show competition locations and popular landmarks in detail on studio monitors during broadcasts. To manage the data and accurately present the geospatial context for the Games, NBC Sports paired its 3D models of stadiums with Cesium for Unreal and Google’s Photorealistic 3D Tiles.

Paris is among the 2,500 cities Google Maps Platform has made available as Photorealistic 3D Tiles: high-res imagery draped over 3D mesh and formatted as 3D Tiles, the OGC community standard created by Cesium to optimize streaming of massive 3D geospatial data. With Google’s extensive coverage, Photorealistic 3D Tiles were designed for city scale, and even down to a city block, providing details viewers expect to see in the real world. NBC Sports imports Photorealistic 3D Tiles into its Unreal Engine projects through Cesium ion, where NBC Sports also hosts its 3D models of venues used for the Games. Smooth rendering of these geospecific 3D datasets and realistic lighting enable NBC Sports to orient and immerse viewers.

“Cesium made it easy for our team of Unreal artists to manipulate Google’s Photorealistic 3D Tiles, building projects that showcase the real-world data to viewers without needing to devote additional resources to acquiring the data. The platform’s speed and quality fit right into our workflow,” said Wade Echer, VP of On-Air Graphics at NBC Sports. “Using Cesium in this manner allowed us to minimize the hours needed to accomplish the job, freeing up other artists for other projects.”

Ocean Exploration Trust/NautilusLive: Orbit to Dive

The launch point for Ocean Exploration Trust’s expeditions is Exploration Vessel (E/V) Nautilus, a 68-meter (224-foot) research ship. E/V Nautilus has space for interdisciplinary teams, labs, and remotely operated vehicles (ROVs). Capable of reaching depths of 4,000 meters (13,000+ feet) ROV Hercules is equipped with lights, high-resolution cameras, and sensors, and it can carry special instrument packages like the widefield camera array to capture high-res video and images for seafloor photogrammetry. In exploring previously unexplored deep-sea habitats worldwide, OET often must acquire data to create their own high-resolution maps. Because OET shares mapping and ROV operation data, expeditions contribute to US and international ocean and technology exploration strategies. This season’s ten expeditions are underway, live streaming daily, with real-time results available to the public.

Funded by NOAA Ocean Exploration and the Office of Naval Research, the RUMI project is growing in its applications for both educational and scientific audiences. The project brings together the images and video from ROV Hercules, bathymetric point clouds from E/V Nautilus’s multibeam echosounder, and other dive observations in a georeferenced digital environment. 

The team at Ocean Exploration Trust and its expedition partners gather vast amounts of data from previously unexplored areas, thousands of meters below the sea surface. “Combining these disparate data streams in one 3D space with Cesium is a unique alternative to downloading our data and using a spreadsheet,” said Jonathan Fiely, OET’s Media Production Specialist and the RUMI Co-Lead. “It’s a powerful way to discover our data in an interactive and engaging manner.”

In building digital models, RUMI uploads its data about the ocean to Cesium ion for hosting and tiling into 3D Tiles, the most efficient way to stream massive, detailed models and combine them for visualization and analysis. Cesium for Unreal’s built-in georeferencing system ensures these models are accurately placed on a WGS84 globe. The team accesses Cesium World Bathymetry for areas along coastlines and inland topographic coverage, to provide broader geospatial context.
