摘要

The flexible pinhole camera allows modulating the sampling rate over the field of view with fine granularity. It inexpensively renders complex datasets by projection followed by rasterization. The resulting image is a coherent nonuniform sampling of the dataset that matches the local variation of the dataset's importance.
