This 2023.1 release of LuciadLightspeed brings a structural improvement to the 3D Tiles Engine, also called Meshup. This engine was added with our 2018 product release. After five years, we decided to refresh it to make it leaner and more powerful.
This release also includes important security upgrades and bundles a set of specific enhancements, all based on user feedback. Please also read our advanced notice of the minimum Java version for LuciadLightspeed for next year and beyond.
The 3D Tiling Engine, also referred to as “Meshup”, has been structurally improved.
As a result, tiling your data in the 2023.1 release:
Uses less memory
Produces smaller output results, using fewer tiles
This not only improves processing time, but also decreases time spent downloading the data in the client.
The difference is most noticeable in large datasets, as well as datasets with repeating textures.
The updated algorithms are enabled by default. If you are new to this topic, the article Processing meshes into OGC 3D Tiles will help you get started.
MBTiles is an open format for storing tile sets, based on the SQLite database. MBTiles can contain raster or vector tile sets. LuciadLightspeed already supports MBTiles raster data. This release adds support for MBTiles vector data. Typically, the MBTiles vector format stores data like administrative boundaries, road networks, or points of interest.
For many years, we have fixed the minimum Java version for LuciadLightspeed to 8. With this release, we are giving advanced notification that the LuciadLightspeed 2023.x releases will be the last releases supporting Java 8. For the LuciadLightspeed 2024.0 release, we plan to raise the minimum version to Java 17. We will continue supporing both the Oracle JDK and OpenJDK.
Going forward, we aim to support the latest Java LTS version in our latest release. The minimum JDK/JRE requirements will never change with a minor upgrade, an upgrade from 2022.0 to 2022.1, for instance, or with a patch release of LuciadLightspeed.
This also applies to LuciadFusion.

This 2023.1 release of LuciadLightspeed includes many security upgrades. The release notes provide full detail on the upgraded, removed, and added dependencies. Please look for "security updates" in the upgrade considerations.
Starting from the 2031.1 release, you only need a new product license for a major LuciadLightspeed product version.
More specifically, for version 2022.0 and 2022.1, you still need separate licenses. If you use your license file for LuciadLightspeed version 2023.0 with LuciadLightspeed version 2023.1, it will work. Of course, both product versions must have matching configurations, with an equivalent product name, product tier and options list.
- DAFIF Path Point record support
DAFIF Path Point records are now supported. These records are used to store the path to be followed to land on the runway. In the past, a radar (ILS) was used for the final part of the approach before landing on the runway. GPS-based systems rely on a lateral and vertical path that needs to be followed, which is the information stored in Path Point records.
- Support for Asterix Category 34
This release adds support for radar status messages encoded as Asterix Category 34. This category and its description have been added to the Overview of the ASTERIX specifications for the supported categories in the product documentation.
- AutoCAD DWG 2018 support
LuciadLightspeed now supports DWG 2018 files.
- SLD road styling documentation
