FrustumDecorator Class

Beta  

Decorates the viewport with a graphical depiction of a Frustum. This is obviously only useful when drawn inside a viewport using a different Frustum. Options for doing so include:

  • Having more than one viewport, and drawing the frustum of one viewport inside the other viewports; and
  • Allowing the user to take a snapshot of the current frustum, then navigate the view to inspect it within the same viewport.
