A Comparison of Three Visual Representations of Complex Multidimensional Accounting Information

Abstract: This study investigates the relationship between three visual representations (two‐dimensional, three‐dimensional fixed, and three‐dimensional rotatable) of multidimensional data, and the subjects' ability to make predictions based on the data. Output of a momentum accounting system was simulated and graphics were rendered based on that information. An interactive computer program was developed and used to administer the laboratory experiment and collect results. Subjects made prediction decisions based on the graphics produced for four companies. Each subject made predictions for one type of graphics representation for each of the four companies. Subjects using three‐dimensional data that could be rotated provided the most accurate predictions. This finding is significant in a systems environment where visualizations and graphics are steadily increasing. The results should be considered when developing systems to provide accounting system users with information for making decisions, especially when the i...

Computer Graphics Programming: Gks - The Graphics Standard

Abstract: Why should wait for some days to get or receive the computer graphics programming gks the graphics standard book that you order? Why should you take it if you can get the faster one? You can find the same book that you order right here. This is it the book that you can receive directly after purchasing. This computer graphics programming gks the graphics standard is well known book in the world, of course many people will try to own it. Why don't you become the first? Still confused with the way?

Visyllable Based Speech Animation

Abstract: Visemes are visual counterpart of phonemes. Traditionally, the speech animation of 3D synthetic faces involvesextraction of visemes from input speech followed by the application of co-articulation rules to generate realisticanimation. In this paper, we take a novel approach for speech animation — using visyllables, the visual counterpartof syllables. The approach results into a concatenative visyllable based speech animation system. The key contributionof this paper lies in two main areas. Firstly, we define a set of visyllable units for spoken English along withthe associated phonological rules for valid syllables. Based on these rules, we have implemented a syllabificationalgorithm that allows segmentation of a given phoneme stream into syllables and subsequently visyllables. Secondly,we have recorded the database of visyllables using a facial motion capture system. The recorded visyllableunits are post-processed semi-automatically to ensure continuity at the vowel boundaries of the visyllables. We defineeach visyllable in terms of the Facial Movement Parameters (FMP). The FMPs are obtained as a result of thestatistical analysis of the facial motion capture data. The FMPs allow a compact representation of the visyllables.Further, the FMPs also facilitate the formulation of rules for boundary matching and smoothing after concatenatingthe visyllables units. Ours is the first visyllable based speech animation system. The proposed technique iseasy to implement, effective for real-time as well as non real-time applications and results into realistic speechanimation.

Peer-to-peer parallel processing graphics accelerator

Abstract: A parallel processing graphics accelerator accelerates graphics rendering devices by being a front-end graphics pre-processor. The accelerator has a plurality of digital signal processors, where each processor has an input in communication with a request bus and an output, and the digital signal processors are arranged in a peer-to-peer configuration so as to process on a cyclical basis each successive graphics request available on a request bus. Related methods are also provided.

Data stream splitting and storage in graphics data processing

Abstract: A computer graphics system splits vertex data into first and second streams and stores the streams in separate regions of memory. In a specific embodiment, the first stream includes positional data and the second stream includes non-positional color and texture data. A visibility subsystem uses only the first stream to perform visibility processing, thus reducing bandwidth requirement. The rendering system processes data from subsets, identified by the visibility subsystem, of both streams required to render the visible part of a scene.
