An application of color graphics to the display of surface curvature

Abstract: In developing a mathematical representation for a surface, designers currently must use line drawing graphics to examine the curvature of a line in a plane, a two-dimensional analysis. By combining a result from differential geometry with the use of color raster graphics, the method described in this paper provides a means for the designer to examine surface curvature, a three-dimensional analysis. In particular, a formulation for the Gaussian and average curvatures is given and it is shown how these indicate the presence or absence of protrusions, hollows, etc. in a surface, i.e., how, where, and by how much the surface curves.Showing a fourth variable, curvature in this case, over a three-dimensional surface is difficult, if not impossible with traditional line drawing computer graphics. The method described solves this problem by using color as a fourth dimension. Examples are given, including both known shapes (torus) and automotive parts (hood, fender).

WIP: the automatic synthesis of multimodal presentations

Abstract: Due to the growing complexity of information that has to be communicated by current AI systems, there comes an increasing need for building advanced intelligent user interfaces that take advantage of a coordinated combination of different modalities, e.g., natural language, graphics, and animation, to produce situated and user-adaptive presentations. A deeper understanding of the basic principles underlying multimodal communication requires theoretical work on computational models as well as practical work on concrete systems. In this article, we describe the system WIP, an implemented prototype of a knowledge-based presentation system that generates illustrated texts that are customized for the intended audience and situation. We present the architecture of WIP and introduce as its major components the presentation planner, the layout manager, and the generators for text and graphics. To achieve a coherent output with an optimal media mix, the single components have to be interleaved. The interplay of the presentation planner, the text and the graphics generator will be demonstrated by means of a system run. In particular, we show how a text-picture combination containing a crossmodal referring expression is generated by the system.

Sketching with Style: Visual Search with Sketches and Aesthetic Context

Abstract: We propose a novel measure of visual similarity for image retrieval that incorporates both structural and aesthetic (style) constraints. Our algorithm accepts a query as sketched shape, and a set of one or more contextual images specifying the desired visual aesthetic. A triplet network is used to learn a feature embedding capable of measuring style similarity independent of structure, delivering significant gains over previous networks for style discrimination. We incorporate this model within a hierarchical triplet network to unify and learn a joint space from two discriminatively trained streams for style and structure. We demonstrate that this space enables, for the first time, styleconstrained sketch search over a diverse domain of digital artwork comprising graphics, paintings and drawings. We also briefly explore alternative query modalities.

The Graphics PARCUM* System: A 3D Memory Based Computer Architecture for Processing and Display of Solid Models

Abstract: The concept of a computer architecture for processing and display of spatially ordered data is presented in this paper. The central part of the architecture is a memory cube in which the objects can be processed in their real shape as a three‐dimensional data array. The development has been rendered possible at reasonable costs through the rapid progress in the realm of VLSI‐memory technology.
