nimbus process mapping

Phenomenon: The Nimbus process automatically exits when it starts. When using storm 0.9.3 and Storm 0.9.2, if the abnormal shutdown, TP does not normally kill the case, the second submission of the topology will encounter the following problems The following problems occur repeatedly 2014-12-01t20:31:09.797+0800 b.s.d.supervisor [INFO] 9ce9ed02-8da3-48fe-b3d6-b95b94910fb7 still hasn ' t startedView Supervis

Shadow mapping has become standard for the current 3D games. The traditional sm+pcf can realize the hard Shadow in the sunlight environment well, but if the soft Shadow produced by dim light is to be realized, either the effect is too blunt (sample number is less) or inefficient (sample number of times). As a result, more and more games are starting to use soft shadow algorithms that take full advantage of hardware features.Here mainly summarizes vari
