Vuforia engine in unity

If you are building an application with Vuforia in Unity for Android, and your application size the APK compressed file exceeds MB, you should consider some measures to reduce its size. We present in this article various suggestions and how to use the OBB expansion file in Unity. The file size limit is currently set to MB. If the size of your app is due to the use of large files, such as videos, 3D models and textures, or other Unity assets, you may want to consider hosting them externally, such as on a server.

This way, the assets are downloaded via the network and used at runtime which dramatically reduces your app size since they are not packaged with the app.

Please refer to the official Unity Asset Bundle documentation for more details about this feature:. In the section below, we describe the practice of using expansion files and loading dataset files from there. While you are allowed to use the OBB split option with Vuforia, you should be aware that certain Vuforia functionalities may need to be handled in an alternate manner. In particular, the database loading feature is affected as the dataset files.

The custom script should read your dataset.

You can use this capability to overlay guided step-by-step instructions on top of machinery for the industrial enterprise or add digital features and experiences to a physical product or game. Vuforia Engine offers a broad range of features and targets to make your AR development process more flexible. One of our newest features, Vuforia Model Targets, is a key capability for both commercial and industrial uses.

Model Targets allow applications to recognize physical objects like machines, automobiles, or toys and track them based on a CAD or digital 3D model. For industrial uses, this feature can provide assembly workers and service technicians with AR work instructions and procedural guidance while in the factory or out in the field. Existing Vuforia Engine apps that were built for phones and tablets can easily be configured in Unity to run on HoloLens.

Add the Vuforia Engine package as described here. The sample provides a complete HoloLens project including pre-configured scenes that can be deployed to a HoloLens. The scenes show how to use Vuforia Image Targets to recognize an image and augment it with digital content in a HoloLens experience. You can easily substitute your own content in the scenes to experiment with the creation of HoloLens apps that use Vuforia Engine.

Developing a Vuforia Engine app for HoloLens is fundamentally the same as developing Vuforia Engine apps for other devices. You can then apply the build settings and configurations described in the section below.

In the portal, developers have access to the Vuforia Engine Forums where they can join community discussions, a library with in-depth documentation on all the Vuforia Engine Features, and the Vuforia Target Manager where users can create their own custom Targets.

Device Tracking maintains tracking even when a target is no longer in view. It's automatically enabled for all targets when the Positional Device Tracker is enabled. Vuforia Engine automatically fuses the poses from camera tracking and HoloLens's spatial tracking to provide stable target poses independent of whether the target is seen by the camera or not.

In these cases, the DefaultTrackableEventHandler script that is used on all targets continues to render augmentation content. The developer can control this behavior by implementing a custom trackable event handler script. The Vuforia Engine offers three modes that can be selected: default, for optimizing speed, and for optimizing quality.

Since we want to perform Image recognition, we first have to tell vuforia what to detect or identify and then track it. We achieve this by defining Image Targets. Image targets represent images that the vuforia engine can detect and track. These Images can be anything, although it is ideal to have an Image with more distinct features as it vastly improves tracking of the image especially, in visually noisy environments.

A set of these Image targets will be stored as a Database. This works for smaller datasets, but for larger datasets, it is ideal to store this on the cloud, such are called Cloud Databases. Databases and targets have to be created from the Vuforia developer portal. Navigate to the Target Manager on the portal website and create a new Database.

Name it and select the type as Device. Set the type to Single Image and browse and upload your image. You can also use the demo Image I used from here. Set the width to 0.Taylor has 1,841 rushing yards and 13 touchdowns this season to lead the Badgers.
