Interactive programs that display or manipulate graphics often need to update those graphics quickly in response to external input. Upon external input, such programs would ideally incrementally update only the parts of the output graphics that actually changed. However, in practice, programmers must write and maintain complex, hand-written procedures to support incremental updates for graphics programs. We propose a technique to create graphics pipelines that are easy to write and maintain, but have incremental performance comparable to efficient hand-written implementations. We target graphics pipelines written in Halide, a domain-specific language and compiler for building image and array processing code. From a Halide pipeline, we synthesize an incremental pipeline that efficiently updates the result of the original computation. We plan to evaluate the performance of our synthesized pipeline against both hand-written incremental pipelines and existing techniques for incremental computation on an image compositor benchmark.
