SDPSL

SDPSL provides tools for discovering a RenderMan shader's arguments at runtime in a render-engine neutral way, either with external, per-shader XML metafiles, or by parsing a shader's source directly. This significantly simplifies the development of render-engine-neutral 3D graphics tools, by eliminating linking to multiple, proprietary parsing libraries (such as libslcargs.a for BMRT, libsloargs.a for PRMan, etc.) It also allows a shader author to communicate a much richer set of data to modelling apps in a standardized way. For example, a shader metafile can specify that a string argument is intended for use as a texture; a modelling app can use this information to adjust its UI accordingly.
