Spark : modular, composable shaders for graphics hardware
Abstract/Contents
- Abstract
- Real-time computer graphics have become a ubiquitous part of modern life. Rich user interfaces and interactive games appear on screens ranging from mobile phones to stereo-3D TVs. Programmable graphics \emph{pipelines} have been central to delivering these compelling experiences. Shaders - programs that describe the shape, movement, and appearance of rendered objects - run in the stages of these pipelines, and are used to define the "look and feel" of a production. The demand for rich, immersive experiences motivates the use of increasingly complex shaders. In creating these complex real-time shaders, programmers should ideally be able to decompose code into independent, localized modules of their choosing. Current real-time shading languages, however, enforce a fixed decomposition into per-pipeline-stage procedures. Program concerns at other scales - including those that cross-cut multiple pipeline stages - cannot be expressed as reusable modules. We present a shading language, Spark, that improves support for separation of concerns into modules. A Spark shader class can encapsulate a program feature that maps to more than one pipeline stage, and can be extended and composed using object-oriented inheritance. We first discuss the design of this language: its origins, goals, and key design choices. We then describe our implementation of a compiler, standard library, and runtime system for Spark, targeting current programmable graphics hardware. Finally, we evaluate this implementation and demonstrate that it achieves our modularity goals without compromising performance: in our tests, shaders written in Spark achieve performance within 2\% of Microsoft's High Level Shading Language (HLSL).
