True Impostors
True Impostors offers an efficient method for adding a large number of simple models to any scene without having to render a large number of polygons. The technique utilizes modern shading hardware to perform ray casting into texture defined volumes. To achieve this, a virtual screen is set up in texture space for each impostor and inherits the same camera dependent orientation as the impostor....
متن کاملTwo of These or Two of Those?
Symmetrically dividing neuroepithelial cells may produce two daughters that are both proliferating or both postmitotic, as highlighted by Zigman et al. in this issue of Neuron and Sanada and Tsai in a recent issue of Cell. Here, I will attempt to offer a simple explanation why these results may be so different.
متن کاملSP-Octrees Visualization Using Impostors
SP-Octrees (Space-Partition Octrees) allow a multiresolution representation of polyhedral objects, and have been successfully used in progressive transmission. Nonetheless, the SP-Octree is a solid modeling structure, intended to solve problems as solid intersections and point inclusion tests. At intermediate levels of the SP-Octree, the visualization is a rough approximation of the object due ...
متن کاملExposing Computationally-Challenged Byzantine Impostors
Internet protocols permit a single machine to masquerade as many, allowing an adversary to appear to control more nodes than it actually does. The possibility of such Sybil attacks has been taken to mean that distributed algorithms that tolerate only a fixed fraction of faulty nodes are not useful in peer-to-peer systems unless identities can be verified externally. The present work argues agai...
متن کاملRussian Genitive Plurals are Impostors
(1) a. Inflectional paradigms aspire to “avoid homophony”. The Russian nominative singular and genitive plural endings reflect a transderivational attempt to minimize homophony across inflectional endings. b. Inflectional paradigms require transderivational reference: one cannot compute the Russian genitive plural without knowing what the nominative singular ending is. c. Markedness-based neutr...
