Questions on Augmented Reality + Vuforia. With Answers.
What is Vuforia?
The Vuforia Engine is the most widely used platform for AR development, with support for leading phones, tablets, and eye-wear. Developers can easily add advanced computer vision functionality to Android, iOS, and UWP apps, to create AR experiences that realistically interact with objects and the environment.
The Vuforia Engine Library is also organized by major feature categories. The major feature categories are Images, Objects and Environments.
What is a reco?
A "reco" occurs when your app recognizes a target in your Cloud Database.
What are Model Targets?
Allow you to recognize objects by shape using preexisting 3D models. Place AR content on a wide variety of items like industrial equipment, vehicles, toys, and home appliances.
What are Image Targets?
Attach content onto flat images, such as print media and product packaging.
What are Object Targets?
Created by scanning an object. They are a good option for toys and other products with rich surface details and a consistent shape.
What are Multi-Targets?
Created using more than one Image Target and can be arranged into regular geometric shapes (e.g. boxes) or in any arbitrary arrangement of planar surfaces.
What are Cylinder Targets?
Recognize images wrapped onto objects that are approximately cylindrical in shape (bottles, coffee cups, soda cans).
What are VuMarks?
Customized Markers that can encode a range of data formats. They support both unique identification and tracking for AR applications.
What is the External Camera?
Access video data from a camera outside of the one in a phone or tablet when creating AR experiences.
What is the Ground Plane?
Enables you to place content on horizontal surfaces in the environment like tables and floors.
What is Vuforia Fusion?
Designed to provide the best possible AR experience on a wide range of devices. It senses the capabilities of the underlying device and fuses them with Vuforia Engine's features, allowing developers to rely on a single Vuforia API for an optimal AR experience.
What is Object Recognition?
Enables Object Targets to be created by scanning physical objects. It allows you to create apps that recognize and track intricate rigid objects.
What is the Cloud Recognition Service?
Helps recognize a large set of images. Database is frequently updated.
What is Vuforia Web Services API?
Allows you to manage the large image databases in the cloud efficiently and enables you to automate your workflows by direct integration into your current management systems.
What is the Vuforia Engine Driver Framework?
Allows developers to provide and consume data from external systems through Vuforia Engine. This framework provides access to External Camera features. The External Camera defines all specifics required for Vuforia Engine to access external image sources.
Where should the AR camera be placed in the scene?
Anywhere, because the Vuforia Tracker handles camera and target positioning automatically at Runtime, BUT it's helpful to have the AR camera looking at the scene contents so that you can use the camera Preview, and also when using Play Mode without a webcam.
What is Z-fighting?
Occurs when the depth buffer confuses the distances of textures that are very near each other.
Appears as a shimmering or flickering effect.
Adjusting the Clipping Plane can help to resolve this.
