This paper presents a framework for the real-time rendering of plant leaves with global illumination effects. Realistic rendering of leaves requires a sophisticated appearance model and accurate lighting computation. For leaf appearance we introduce a parametric model that describes leaves in terms of spatially-variant BRDFs and BTDFs. These BRDFs and(More)

This paper present a Functional Alternatives Transaction Model (short for FATM), which provides multiple execution path for the important transactions. Based on FATM, we divide the alternative into multiple Critical Operation Region (short for COR). After that we analyze and propose the strategies that can improve the concurrence of the alternatives. The(More)
Environment mapping, or reflection mapping, has been widely used in the game and movie industries to give objects a realistic illumination atmosphere. For moving objects, direct frame-by-frame calculation of environment maps and correspondence-based interpolation are both impractical for real-time applications due to the large computational costs. To deal(More)
