Detailed Description

This array holds all the visible objects in one liveViz3d computation.

Users should inherit all their visible classes from this kind of array element.

Rationale: By keeping all viewables in one big array, we can update the viewpoint using a single broadcast. The sensible alternative of keeping several different arrays (e.g., one array of tiles, one of buildings, one of trees) would result in multiple broadcasts, and make addressing more complicated.

Here is the caller graph for this function:

void LV3D_Array::addViewable

(

CkViewable *

v

)

Add this viewable to our set.

The viewable is still owned by the caller, but must survive until removed or the element is destroyed.

This routine is often called exactly one per array element lifetime, and often from the constructor or pup routine.

For liveViz, the array element basically only exists to provide network access for this CkViewable.

There is a small fixed limit on the number of CkViewables you can add. 1 is safe.

void LV3D_Array::LV3D_Viewpoint

)

[virtual]

This request is broadcast every time a client viewpoint changes.

Internally, it asks the stored CkViewables if they should redraw, and if so, queues up a LV3DRenderMsg.
