We present an automated approach for high-quality preview of feature-film rendering during lighting design. Similar to previous work, we use a deep-framebuffer shaded on the GPU to achieve interactive performance. Our first contribution is to generate the deep-framebuffer and corresponding shaders automatically through data-flow analysis and compilation of the original scene. Cache compression reduces automatically-generated deep-framebuffers to reasonable size for complex production scenes and shaders. We also propose a new structure, the indirect framebuffer , that decouples shading samples from final pixels and allows a deep-framebuffer to handle antialiasing, motion blur and transparency efficiently. Progressive refinement enables fast feedback at coarser resolution. We demonstrate our approach in real-world production.

The threat of securities class actions haunts every public company. The threat probably is worst for information technology companies. Similarly, Y2K claims may threaten every company, and probably are greatest for those most dependent on information technology. It follows that the combination of these risks ± of securities class actions resulting from any of the countless types of possible Y2K claims ± presents public companies with a formidable problem. This article provides an overview of the implications of Y2K for securities class actions, and identifies some practical steps for minimizing the risks from Y2K‐related securities claims.
