轨迹球控制：如果只用鼠标来控制你的模型是不是很酷?轨迹球可以帮你做到这一点，我将告诉你我的实现，你可以把它应用在你的工程里。我的实现是基于Bretton Wade’s，它是基于Ken Shoemake’s 实现的，最初的版本，你可以从游戏编程指南这本图上找到。但我还是修正了一些错误，并优化了它。轨迹球实现的内容就是把二维的鼠标点映射到三维的轨迹球，并基于它完成旋转变化。

Cognitive radio frequency spectrum detection-The spectrum sensing of a wideband frequency range is studied by dividing it into multiple subbands. It is assumed that in each subband either a primary user (PU) is active or absent in a additive white Gaussian noise environment with an unknown variance. It is also assumed that at least a minimum given number of subbands are vacant of PUs. In this multiple interrelated hypothesis testing problem, the noise variance is estimated and a generalised likelihood ratio detector is proposed to identify possible spectrum holes at a secondary user (SU). Provided that it is known that a specific PU can occupy a subset of subbands simultaneously, a grouping algorithm which allows faster spectrum sensing is proposed. The collaboration of multiple SUs can also be considered in order to enhance the detection performance. The collaborative algorithms are compared in terms of the required exchange information among SUs in some collaboration
