A Projection that is updated dynamically at the specified Update Delta. The class can be used to stream projection data to Projection clients, like Projected Raster Overlay. Note to Implementers: When implementing a derived class of ProjectionStream, you must provide an implementation for the Update method.

Update

When overridden in a derived class, updates the projection data associated with the projection stream at the specified time. When the Update method is called, the projection stream contains the current projection data. The time parameter provides the current and next Scene Manager time. Return true if the projection data was updated, otherwise return false.

UpdateDelta

Gets or sets the update delta of the projection stream in seconds. The Update Delta defines the interval at which the Update method will be called. The default Update Delta is 0, which will call the Update method every time the Scene Manager time changes. When animating, this means the Update method would be called on every animation step.
