    In designing colors for digital visualization systems. one of the most critical factors is the interaction between size and color appearance. Whereas artists and visual designers understand this, recommendations for using color in visualization rarely address the issue, or even recognize it. The goal is to keep the user focused on the data, with color simply one of many tools used toward problem s... View full abstract»

    Use and creation of computer graphics can be effectively taught to beginning design students in the context of discipline-specific design projects. In particular, a case study of the pedagogy implemented by the New Jersey Institute of Technology's College of Architecture + Design provides examples of how teachers harness the students' desire to create and provide educational opportunities for unde...

    Using measurements of real-world samples of metals, the proposed approach verifies predictions of bidirectional reflectance distribution function (BRDF) models. It employs ellipsometry to verify both the actual polarizing effect and the overall reflectance behavior of the metallic surfaces. View full abstract»

    A new method for interactive rendering of complex lighting effects combines two algorithms. The first performs accurate ray tracing in heterogeneous refractive media to compute high-frequency phenomena. The second applies lattice-Boltzmann lighting to account for low-frequency multiple-scattering effects. The two algorithms execute in parallel on modern graphics hardware. This article includes a v... View full abstract»

    Salt-based aging plays an important part in the realism of scenes featuring stone structures and monuments. A proposed model, based on physical behaviors and principles, replaces the simulation of complex physical formulations with ad hoc algorithms. It leads to plausible results, ultimately helping designers create aging patterns on affected objects. View full abstract»

    A proposed method visualizes the surface appearance of living human brain tissue. The goal is to investigate whether realistic models of living anatomy are possible and, if so, whether they provide added value to anatomy education and training simulators. From calibrated photography of exposed brain tissue and suitable alternatives, experiments provided data for a bidirectional reflectance distrib... View full abstract»

    A proposed rule-based editing metaphor intuitively lets artists create buildings without changing their workflow. It's based on the realization that the rule base represents a directed acyclic graph and on a shift in the development paradigm from product-based to rule-based representations. Users can visually add or edit rules, connect them to control the workflow, and easily create commands that ... View full abstract»

    Computer animation researchers have been extensively investigating 3D facial-expression synthesis for decades. However, flexible, robust production of realistic 3D facial expressions is still technically challenging. A proposed modeling framework applies sparse coding to synthesize 3D expressive faces, using specified coefficients or expression examples. It also robustly recovers facial expression...

    Early detection and rapid response to infectious-disease outbreaks rely on effective decision making based on information from disparate sources. To improve decision-making in outbreak detection and response, it's important to understand how public health practitioners seek relevant information. Epinome, a user-centric visual-analytics system, supports research on decision-making in public health,... View full abstract»
