This sample demonstrates the use of the Focus Areas in a Scene component.
Focus areas help to focus the viewers' attention to a certain part of the scene. Focus areas can be captured in slides and shared as part of the webscene.
The sample includes basic UI controls to choose focus area style Dark or Bright, or None to disable the focus area. A minimal UX to modify the focus area is implemented using the SketchViewModel class.
Click inside the focus area to modify it. With the first click, it is possible to move, scale or rotate the area. With the second click inside the focus area, single vertices of the shape can be adjusted.
