4.1 Options

Options are parameters of the graphic state that apply to the entire scene. All options are saved at each FrameBegin and restored at the corresponding FrameEnd call. It is important to set these options before the WorldBegin...WorldEnd block since it is a RenderMan assumption that rendering may begin any time after WorldBegin; all options must be fixed by then. Also, and contrary to transforms, the order in which options appear is not important.

The RenderMan API declares a standard set of options (which are used to control camera and image parameters) and opens a door to implementation specific options through the RiOption call. 3Delight supports all of the standard options and has some specific calls; both groups are described in the following sections.

4.1.1 Image and Camera Options
4.1.2 Implementation Specific Options
