    OpenGL has become the standard application programming interface (API) for teaching introductory computer graphics courses in computer science, engineering, and mathematics. Faculty can rely on many OpenGL features-such as its availability across platforms, its backward compatibility, and its defaults-to support a variety of teaching styles and course goals. More recently, OpenGL has changed radic... View full abstract»

    Real-time rendering of large scale vector maps over terrain surfaces requires displaying substantial numbers of polylines and polygons. The proposed approach simplifies such maps, permitting more efficient rendering and reducing latency in the display and manipulation of a virtual environment. View full abstract»

    Current colorization based on image segmentation makes it difficult to add or update color reliably and requires considerable user intervention A new approach gives similar colors to pixels with similar texture features. To do this, it uses rotation-invariant Gabor filter banks and applies optimization in the feature space. View full abstract»

    A VR-based training system for practicing biopsies simulates ultrasound imagery by stitching multiple ultrasound volumes on the basis of a 3D scale-invariant feature transform algorithm. In addition, a six-degree-of-freedom force model delivers a realistic haptic rendering of needle insertion. View full abstract»

    EasyToy is an industrial plush toy design system for novices. Editable sketching curves combine the advantages of free-form strokes and the controllability of B-spline curves. Users can continuously edit each curve to refine designs. EasyToy provides a small set of simple tools with which users can easily construct sophisticated toy models comparable to those that professional systems produce. View full abstract»

    This tutorial presents probability theory techniques for boosting linear algorithms. The approach is based on statistics and uses educated guesses instead of comprehensive calculations. Because estimates can be calculated in sublinear time, many algorithms can benefit from statistical estimation. Several examples show how to significantly boost linear algorithms without negative effects on their r... View full abstract»

    GPU shaders aren't just for special effects. Previously, I looked at some uses for them in visualization. Here, the idea continues. Because visualization relies so much on high speed interaction, we use shaders for the same reason we use them in effects programming: appearance and performance. In the drive to understand large, complex data sets, no method should be overlooked. This article describ... View full abstract»

    The authors developed a method for manufacturing customized insoles. It leverages advances in pressure analysis of the foot, including research on insole materials' mechanical properties and the design of insole components. Using a plan tar pressure measurement system and computer numerical control (CNC) or rapid-prototyping technology, it determines the distributed average pressure for each regio...
