Creating a simple color tracker
To include color tracking on your scene just complete the following steps.
1. Import ColorTracker package.
2. Go to the folder ColorTracker/Scripts/Integration on the project explorer.
3. Drag the ColorTrackerPanel script to the GameObject containing the main camera on
your scene.
4. Choose the input mode and the tracker accurancy. Then add as many color targets as
you need to use. You will notice there are two input modes: Screen and Webcam. Those
modes are examples about how you can implement your own input modes. The Screen
mode captures everything is drawn on the view. The Webcam mode captures the image
from the camera sensor on device.
6. Create a new canvas to render the tracks, go to menu GameObject -> UI -> Canvas.
7. Connect the ColorTrackerRender component to the Canvas, graphic model, and
ColorTrackerPanel. For graphic model you can use the “Indicator” prefab included in
the ColorTracker/Demo/Prefabs folder.
