Item Design of an On-Chip Reflectance Map(The Eurographics Association, 1995) Scheltinga, Jeroen Terwisscha van; Smit, Jaap; Bosma, Marco; W. StrasserA reflectance map design is described which uses a minimal amount of memory for the table, in order to be applicable as an on-chip shader. The shader is designed for use with the volumetric super resolution hardware, which performs shading at supersampled locations. However, the design may be used as well to support surface visualization applications. Despite the small table size, the image quality obtained is excellent, even on smooth surfaces.Item Graphics Algorithms on Field Programmable Function Arrays(The Eurographics Association, 1996) Smit, Jaap; Bosma, Marco; Bengt-Olaf Schneider and Andreas SchillingThe amount of energy consumed in basic CMOS building blocks, like external RAM, external bus-structures, multipliers, local (cache) memory and on chip bus-structures, is analyzed thoroughly to find ways for substantial improvement of the power consumption of high speed graphics algorithms: A Field Programmable Function Array capable of low-power execution of a wide range of algorithms is introduced. Aspects of the compilation of the volume rendering algorithm to this architecture are discussed.Item Super Resolution Volume Rendering Hardware(The Eurographics Association, 1995) Bosma, Marco; Smit, Jaap; Scheltinga, Jeroen Terwisscha van; W. StrasserThe resolution obtained in volume rendering is greatly increased over known methods through the introduction of super resolution techniques which make it possible to enlarge the view o f the dataset without the introduction of unnecessary positional, gradient and opacity errors. In this paper our "Super Resolution" technique will be introduced along with a corresponding hardware design.
