(one pass per subpixel sample) through the hardware rendering pipeline. The resulting image is very high quality, but the performance degrades in proportion to the number of subpixel samples used by the filter function. This paper describes algorithms for accelerating antialiasing in 3D graphics through low-cost custom hardware. The rendering architecture(More)
BACKGROUND Prevention of the onset of depression in adolescence may prevent social dysfunction, teenage pregnancy, substance abuse, suicide, and mental health conditions in adulthood. New technologies allow delivery of prevention programs scalable to large and disparate populations. OBJECTIVE To develop and test the novel mobile phone delivery of a(More)
We present a new algorithm for best-effort simplification of polygonal meshes based on principles of visual perception. Building on previous work, we use a simple model of low-level human vision to estimate the perceptibility of local simplification operations in a view-dependent Multi-Triangulation structure. Our algorithm improves on prior perceptual(More)
This paper describes algorithms for implementing accurate rendering of CSG and transparency in a hardware 3D accelerator. The algorithms are based on a hardware architecture which performs front-to-back Z-sorted shading; a multiple-pass algorithm which allows an unlimited number of Z-sorted object layers is also described. The multiple-pass algorithm has(More)
A hardware accelerator for 3D ren&ring, based on a mcdifkd scanline algorithm, is presented. The accelerator renders multiple scanlines in parallel with high efficiency, and is optimized for integration into systems that suppr[ high speed data streams (such as video). The architecture has a very high performance/cost ratio, but maintains a low entry cost(More)

MOTIVATION Recently, gene-coexpression relationships have been found to be often conditional and dynamic. Many studies have suggested that single nucleotide polymorphisms (SNPs) have impacts on gene expression variations in human populations. RESULTS The SNPxGE(2) database contains the computationally predicted human SNP-coexpression associations, i.e.(More)

We have provided support for change through (a) faculty development, (b) curriculum revision, and (c) technology friendly field placements. This support for change has led to an Early Childhood program in which 100% of the faculty integrate technology into their teaching, and graduates are better prepared to use technology in their future classrooms.
