Class CM3View
CM3View Class
Class to manage a 3D view. This includes:
- Three.js camera
- Three.js Renderer which renders the scene into the camera (which is tied to the view's element)
- ViewingPlatform - optional platform to allow the camera to move indepenently from the direction of the platform.
Think of an airplane with a pilot, the plane is moving in one direction but the pilot can look in other directions.
- ViewingControls - these are based on the Three.js classes but modified to allow for spatial actions
For mulitple views, these need to move here:
- CanvasElement - the element the scene is displayed in
- CanvasContainer - the DIV that contains the canvas object. This is required to capture resize events and then resize the canvas element.
