One method of directly rendering a three-dimensional volume of scalar data is to project each cell in a volume onto the screen. Rasterizing a volume cell is more complex than rasterizing a polygon. A method is presented that approximates tetrahedral volume cells with hardware renderable transparent triangles. This method produces results which are visually(More)
An important improvement to visualization systems will provide a graphics "window into an application" displaying program data at run-time through an easy-to-use graphical interface. With little or no instrumentation of the application the user will be able to dynamically select data for graphical display as the program executes on a remote computer system.(More)
At the heart of much scientiic computing are the algorithmic kernels often found in numerical software libraries. Numerical analysts and algorithm designers can be aided by various software tools in the design of their algorithms. We present a tool for matrix visualization and its application in the design and development of numerical algorithms for(More)
The CEDAR system under development in the Center for Super-computing Research and Development (CSRD) at the University of Illinois at Urbana-Champaign is a clustered shared-memory multipro-cessor system which can be used to support parallel processing for a wide range of numerical and non-numerical applications. In this paper , we survey selected algorithms(More)
