                         ideas with the objective of speeding up image generation for 
                         irregular grid data sets. For large data sets, however, even the 
                         current fastest algorithms are known to require seconds to 
                         generate each image, making real time analysis of such data sets 
                         very difficult, or even impossible, unless one has access to 
                         powerful and expensive computer hardware. In order to synthesize a 
                         system for handling very large data set analysis, we have 
                         assembled algorithms for rendering, simplification and 
                         triangulation, and added to them some optimizations. We have made 
                         some improvements on one of the best current algorithms for 
                         rendering irregular grids, and added to it some simple 
                         approximation methods in both image and object space, resulting in 
                         a system that achieves high frame rates, even on slow computers 
                         without any specific graphic hardware. The algorithm adapts itself 
                         to the time budget it has available for each image generation, 
                         using hierarchical representations of the mesh for faster delivery 
                         of images when transformations are imposed to the data. When given 
                         additional time, the algorithm generates finer images, obtaining 
                         the precise final image if given sufficient time. We were able to 
                         obtain frame rates of the order of 5 Hz for medium-sized data 
                         sets, which is about 20 times faster than previous rendering 
                         algorithms. With a trade-off between image accuracy and speed, 
                         similar frame rates can be achieved on different computers.",
