VisionLib Release 20.6.1

20.6.1 Release is here

VisionLib Release 20.6.1 is now available at visionlib.com.

This update focuses once more on HoloLens 1 + 2 and adds a significant performance boost while using VisionLib Tracking. Additionally, it brings AutoInit to the XR glasses.

We’ve entirely revised and added new video tutorials. And we give access to the first beta URP extension, which enables to use VisionLib with Unity’s Universal Render Pipeline. › Read on.

More HoloLens #1

Better Tracking Performance

The new update not only makes VisionLib Tracking on HoloLens more stable. It also increases the performance and almost doubles the overall speed when using Model Tracking on the XR device. This means faster tracking of movable objects and more overall performance for Model Tracking on HoloLens:

More HoloLens #2: AutoInit

You can now also use AutoInit on HoloLens 1 + 2, which liberates from initial poses to start tracking. This is in particular a key feature as it eases object registration and tracking, and enables users to detect objects from any viewing angle.

Have a look at the new HoloLens AutoInit example scene and refer to the documentation to get started.

More HoloLens #3: New Parameters

With AutoInit for HoloLens, we also introduce new parameter options:

  • The fieldOfView parameter adds control to improve tracking of small objects on HoloLens 2: you can either set it to wide (default) or narrow to optimize the tracking of small objects.
  • Increase the performance on HoloLens significantly, by setting the useColor parameter “false” in the tracker & input section of your tracking configuration.

To experience AutoInit and test fieldOfView on the device, we’ve added additional voice commands to all HoloLens example scenes and we’ve added a new one scene to test the new behaviour. Use them to find, which setting fits best your tracking target’s size.

Please Note: To improve the performance on HoloLens example scenes, the debug image is not displayed by default anymore and showLineModel is disabled. Both can be re-enabled on runtime using the voice command Show Debug Image.

Setup & Debug Tracking with visLab

visLab is a desktop app to generate and configure VisionLib tracking files. It is a great tool to quick-track custom objects and test their tracking quality. It enables easy debugging of tracking setups and lets you save the results in configuration files that can be re-used e.g. with VisionLib’s Unity SDK.

With this update, we’ve improved the stability and workflow while using visLab. Wizard dialogs now assist during the process and minor changes to the UI make the Bounding Box info more visible: it is a great help to find the right metric of the 3D files used as target reference.

Have you tried it, yet? While visLab isn’t mandatory to setup VisionLib tracking, it nevertheless adds some ease to the process. You can download visLab from the VisionLib Customer Area and use it with your trial or all other licenses.

General Updates

Besides AutoInit and improvements to HoloLens, the new release comes with many more updates and bugfixes. Here an overview on the most relevant ones:

  • We optimized the VisionLib code and reduced the size of the binaries; especially for iOS and Android.
  • To improve coping with wrong metric settings, which may cause bad tracking results, we’ve added a warning that issues and indicates inconsistencies, if the bounding box of the given model appears inappropriate to the (user) given metric.
  • VisionLib’s ImageTracking has a quality parameter now – between 0 (bad tracking) and 1 (good tracking) – and enables to check tracking quality programmatically.
  • We share the first beta of VisionLib’s URP extension, which enables to use VisionLib with Unity’s Universal Render Pipeline. Preview-1 package is available in the Download section.

New Tutorial Videos on Youtube

We entirely revised our Youtube tutorials, which run you through the basic steps to start AR Tracking with VisionLib: from downloading + installing the package up to tracking custom objects.

We’re going to add more video in the next weeks, which will also cover advanced cases, like working with VisionLib’s parameters, or using AutoInit or Multi-Model-Tracking.

On top, we’ve added starter tutorials for working with visLab, which explain the tool and how-to setup tracking configurations with it.

Learn VisionLib – Workflow, FAQ & Support

We help you apply Augmented Reality in your project, on your platform, or within enterprise solutions. Our documentation has a new home, and is now publicly available at docs.visionlib.com. It gets you quickly started with VisionLib – no need to login repeatedly anymore.

We also entirely remastered our Video Tutorials, making them more comprehensive and useful. We’re adding new videos with essential insides for starters and pros alike in the next couple of weeks.

Also, check our revised Example Scenes in the Unity SDK. Our Using VisionLib pages give a good overview on how-to get development started by providing workflows and tools. There is also a page collecting important news & updates of each release.
