AbstractThere are numerous algorithms in graphics and visualization whose performance is known to decay as the topological complexity of the input increases. On the other hand, the standard pipeline for 3D geometry acquisition often produces 3D models that are topologically more complex than their real forms. We present a simple and efficient algorithm that allows us to simplify the topology of an isosurface by altering the values of some number of voxels. Its utility and performance are demonstrated on several examples, including signed distance functions from polygonal models and CT scans.
Visualization is a useful tool in many areas of computer science education. This paper describes the use of visualization in the introduction of object-oriented concepts. A Java application has been developed that allows the user to interact with a visualization of any Java class through the instantiation of objects, the movement of those objects around the class environment, and the activation of class methods. The user may also move conveniently between classes in this visualization.This Object Visualizer is useful for classroom demonstration, individual student use in the laboratory, and class debugging and testing.

scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
