Pattern Examples

RPS 19 includes example RIB files and shaders demonstrating the Patterns that are shipped for use in RIS rendering mode. These examples can be found in the /lib/examples/RIS/scenes directory of your RenderMan Pro Server installation, in the /pattern and /spt/dinosaur subdirectories. Some of the examples are discussed in detail in the pages below. Whether or not you're inclined to open up a terminal window and render along, these pages serve as a broad overview of the features and capabilities of PRMan's RIS mode.

	Dino - The Dino example is deceptively simple. In actuality, it's showing some important, powerful stuff: it's a hierarchical subdivision surface that takes advantage of PRMan's texture atlas support. We've also chosen this example to show off how AOV support has changed in RIS mode...
	Sample Patterns - PRMan includes pattern nodes for all manner of pattern generation. These can be used for texture mapping, color correction, or procedural shading. Additionally, we've provided a PxrSeExpr node that serves as a scriptable pattern generator and combiner, and a PxrOSL node for creating more complex shader networks in a dedicated shading language.
