Version 1.4 Release

What’s new in v1.4
We are constantly adding to and improving udStream which uses our software development kit (udSDK) for unlimited detail 3D data visualisation. Here’s what’s new in version 1.4;
Point Class Classification Off
Point Class Visualisation On

Isolate Key Features With Data Point Classes

Now you can identify features and classes of data while not being concerned with anything else. For example foliage, bitumen, road and rail are now some of the types of features you can isolate and display in your project.

Technical:
• Filter out points based off its classification.

Visualise and Measure Vertical Elevations

The new Section View tool takes a slice of the point-cloud which is then displayed as a side or cross-section. It is useful to visualise and measure vertical elevations. A typical use case might be taking a cross-section of a road to measure its profile, or, to take a slice of a building to inspect its facade.

Technical:

• Incorporates all scene items including point-cloud data, meshed objects, map tiles and measurements

• Can be a created from a single line or multiple line segments

• Hover over a position in the section view to display the same position in the 3D scene

• Optional grid view for reference of the scale of the cross section.

gITF 2.0 Support For Faster Loading

udStream 1.4 now comes with support for the glTF 2.0, a specification for the efficient transmission and loading of 3D scenes and models. You might consider it the gold standard for describing a three-dimensional scene. Fast, flexible and compact, it is great a choice to set up complex scene objects and animations.

Technical:
• To load a file, simply drag and drop the file into udStream.
• udStream currently supports the following glTF 2.0 features:
– Models
– Meshes
– Materials
– Textures
– Animation

WKT Support For Faster Loading

We have expanded support for custom spatial reference systems with the ability to describe your system with custom Well Known Text (WKT).

Technical:
• WKT can now be used to set the camera geozone and during converting
• properly geolocate your model with standard or pre-defined custom coordinate systems.

New Features

  • Added Section View tool
  • Added GLTF 2.0 support
  • Added feature to hide points based on classifications
  • Added (experimental) Temporal Anti-Aliasing
  • Added media placement tool
  • Added performance/quality trade-off slider
  • WKT can now be used to set the camera geozone and during convert

Improvements

  • (Browser) Fixed viewsheds
  • (Browser) Improved 32bit Chrome support
  • Added point count estimation for TIFF conversion
  • Switched the map tiles to use higher performance servers
  • Exporting video sequences create subfolders to avoid overriding/losing previous exports
  • Lots of translation improvements
  • When using native dialogs you can now select multiple files at once for convert
  • The scene explorer enables/disables automatically based on the application complexity
  • udStreamConvertCMD version number tracks the udStream verion
  • udStreamConvertCMD can do clipping from OBB, Cylinder and Sphere shapes
  • udStreamConvertCMD can now convert TIFF, SLPK and (on supported platforms) FBX
  • Added Show All and Hide All buttons for the scene explorer
  • Added “Reload” button on UDS models to stream the model from scratch when there are issues
  • (macOS) udStream is now signed correctly so it will launch without being forced
  • Error states are more clear for conversion and they are also slightly more verbose
  • Mouse Height is now shown in the projection information (only Ellipsoidal height in ECEF)
  • Fixed some issues in the handling of some specific OBJ files
  • OBJ is an option for Export point-cloud from a model with primitives (and LAS is disabled)
  • Fixed reprojection issues for some datums including Hong Kong grid

Bug Fixes

  • Fixed an issue causing visualisations to sometimes be inaccurate in regards to the height above ellipsoid
  • Fixed object highlighting not working when using classification visualisation
  • Fixed an issue where new modals being opened sometimes weren’t focussed correctly
  • (Windows) Fixed issues with mip-maps not working correctly
  • Improved atmosphere flickering/flashing (particularly near the horizon)
  • Fixed some issues related to visualisation effects ‘wobbling’
  • Projects deleted in the portal or by another user are now reflected correctly in udStream
  • Area measurement is more accurate on sloped surfaces and better handles complex intersections
  • Fixed a crash during conversion when more than 34 cores are available
  • Fixed a crash when there are a lot of overlapping UDS models displayed on screen
  • Significant improvements to the stability when exporting a large region of a large point cloud over the internet (far less likely to fail prematurely)

Brisbane city 3D model aerial view

South-East Queensland

Take a virtual tour of this massive 3D model of Brisbane and The Gold Coast

Flythrough massive models of Brisbane (75mm) and the Gold Coast (25mm) with over 196 billion points of aerial photogrammetry data.

A digital twin of a whole city has been entirely prohibitive to present and share globally due to the massive amount of data. udStream rapidly renders and presents this data on standard specification computers with average internet bandwidths.

Essential Settings

• Go to Settings > Maps & Elevation, check Keep Camera Above Ground

Recommended Settings

• Go to Maps & Elevation, select Azure Aerial, adjust Map Height to -40.00m, turn on Digital Elevation Model

• Go to Settings > Appearance > Show Camera Information, adjust Move Speed to speed up and slow down

• Go to Visualisation > Display Mode, select Colour, select Skybox Type > Atmosphere, adjust Time of Day to 12.000

Mt Fuji 3D model aerial view

Mount Fuji

Explore Japan like never before in this huge point cloud data set.

Explore the countryside, highways, powerplants and harbours of Japan’s Shizuoka prefecture. The 7777 km² model is part of Honshu’s Pacific coast dominated by Mt Fuji. It is created from five datasets of 117 billion points from aerial laser survey.

Recommended Settings

• Go to Maps & Elevation, select Azure Aerial, adjust Map Height to -50.00m, turn on Digital Elevation Model

• Go to Settings > Appearance > Show Camera Information, adjust Move Speed to speed up and slow down

Underground Mine

Go underground and explore the mine caverns with amazing detail

Explore over one billion points of terrestrial laser scan data of the underground workings of a mine located 2000 metres below the remote Western Australian desert.

This project is a great example of how a minesite can be used as a digital twin combining up to date LiDAR scans with live IoT feeds for asset tracking, insitu images/document geolocation, survey planning and analysis, OH&S applications, production analysis and more.

Recommended Settings

• Go to Maps > Elevation, select ESRI WorldImagery

• Go to Settings > Appearance > Show Camera Information, adjust Move Speed to 30.000m/s

High altitude image of the Great Barrier Reef 3d model

The Great Barrier Reef

Fly, and swim, through our massive 3D project of the entire Great Barrier Reef

The Great Barrier Reef (GBR) is the largest coral reef ecosystem on Earth and stretches over 2500 km along the north-eastern Australia margin. Bathymetry mapping of this extensive reef system is vital for the protection of the GBR allowing for the safe navigation of shipping and improved environmental management.

This dataset contains bathymetry (depth) products from the compilation of all available source bathymetry data within the Great Barrier Reef into a 30 m resolution Digital Elevation Model (DEM). It contains approximate 770 million points and was originally provided as a 25GB ASC file.

For over a decade (until 2017), deep-water multibeam surveys have revealed the highly complex shelf-edge drowned reefs and continental slope canyons. Airborne LiDAR bathymetry acquired by the Australian Hydrographic Service cover most of the GBR reefs, with coverage gaps supplemented by satellite derived bathymetry.

All source bathymetry data were extensively edited as point clouds to remove noise, given a consistent WGS84 horizontal datum, and where possible, an approximate MSL vertical datum.

Recommended Settings

• Go to Maps & Elevation, select Azure Aerial, adjust Map Height to -500.00m, turn off Digital Elevation Model

• Go to Settings > Appearance > Show Camera Information, adjust Move Speed to speed up and slow down

• Go to Visualisation > Display Mode, toggle between Skybox Type > Atmosphere and Colour, adjust Field Of View
