Abstract: Methods and apparatus solving problems of polygonal approximations of isosurfaces extracted from uniformly sampled volumes increasing in size due to the availability of higher resolution imaging techniques. The large number of primitives represented hinders the interactive exploration of the dataset. Examples of methods are provided for adaptive isosurface extraction that are generally easy to implement and allows the user to decide the degree of adaptivity as well as the choice of isosurface extraction algorithm. The extraction of the isosurface is optimized by warping the volume. In a warped volume, areas of importance (e.g. containing significant details) are inflated while unimportant ones are contracted. Once the volume is warped, any extraction algorithm can be applied. The extracted mesh is subsequently unwarped such that the warped areas are rescaled to their initial proportions. The resulting isosurface is represented by a mesh that is more densely sampled in regions decided as important.

Abstract: Described is a method and system of requirements management including the expression in a requirements management tool of a relationship selected from the group consisting of a satisfaction relationship, an alternative relationship, a conflict relationship, and a content dependency relationship. Described is a requirements management method including a first automatic analyzing of a requirements set to find conflicts, having a conflict free requirements subset and a second automatic analyzing of the requirements set to verify completeness.

Abstract: A method, system, and program product for conducting a trade-off study are described. Under aspects of the present invention, a mapping of logical model to a physical model for a product that is a subject of the trade-off study is provided. Based on the mapping, component(s) for a configuration of the product will be selected from a semantic component library, which is a resource that identifies available components and possible connections there between. For each component selected, an instance will be generated and then graphically connected to other instances. Parameters can then be designated for the connected instances. Once the configuration has been built in this manner, it can be evaluated and revised as needed.
