Project Update: How Vuforia works
When the initial settings are finished, let’s proceed with the project, but first, let’s explain better what Vuforia does
Vuforia is an augmented reality software development kit (SDK) for mobile devices that enables the creation of augmented reality applications. It uses computer vision technology to recognize and track planar images and 3D objects in real time. This image registration capability enables developers to position and orient virtual objects, such as 3D models and other media, in relation to real world objects when they are viewed through the camera of a mobile device. The virtual object then tracks the position and orientation of the image in real-time so that the viewer’s perspective on the object corresponds with the perspective on the target. It thus appears that the virtual object is a part of the real-world scene. source Wikipedia
To use the AR camera we must insert an object in scenes with the script ImageTarget. Vuforia provides a series of images ready to use but we can use any image. For now, I will use one of the default ones.
The image that we will choose will be the marker that will be recognized by the camera. On this marker will appear the objects that we are going to place over in our scene, children of our game object Image Target. They will be rendered in the same positions of the scene view so we have to pay attention to where we place the objects.
Without making a build of the project, Unity allows us to test the prototype using your computer’s webcam.
