Detailed Description

Render-time scene snapshot used by ScanlineRender2 plugin and other render plugins on the same architecture, such as DepthMapRender which is used for light shadow maps.

This structure represents a snapshot of all objects and transforms that are needed to render a certain camera view at a certain time.

Use the next/prev scene methods to access other SlrScenes for motionblur purposes. All SlrScenes shared by the sample renderer will share the same stage, object and light lists so matching objects and lights between scenes means accessing the same one by index in the other SlrScene.
