推箱子游戏,直得对游戏开发的朋友学习或参考.-Sokoban games, straight to the game developers have a friend learning or reference.

蒙特卡洛射线追踪器 本项目是一个使用全局光照算法蒙特卡罗射线追踪绘制虚拟三维场景的程序。 该算法在场景中递归跟踪摄像机发出的光线，并将光线反射到物体表面。 该项目是为Linkopings大学的TNCG15全球照明和渲染课程而设计的。(This project is a program for rendering virtual 3D scenes with the global illumination algorithm Monte Carlo ray tracing.)

说明：  我们描述了所提出的方法对超声（US）信号的压缩多路复用的直接应用。该技术利用压缩多路复用器架构进行信号压缩，并依靠频域中US信号的联合稀疏性进行信号重建。由于换能器元件具有压电特性，因此可以获得有关US信号频率支持的准确先验知识，并且可以在联合稀疏算法中使用。 我们在数值实验中验证了所提出的方法，并显示了它们在秩次缺陷情况下相对于最新方法的优越性。我们还证明，与没有已知支持的重建相比，该技术可显着提高体内颈动脉图像的图像质量。(We describe a direct application of the proposed methods for compressive multiplexing of ultrasound (US) signals. The technique exploits the compressive multiplexer architecture for signal compression and relies on joint-sparsity of US signals in the frequency domain for signal reconstruction. Due to piezo-electric properties of transducer elements, accurate prior knowledge of the frequency support of US signals is available and can be used in joint-sparse algorithms. We validate the proposed methods on numerical experiments and show their superiority against state-of-the-art approaches in rank-defective cases. We also demonstrate that the techniques lead to a significant increase of the image quality on in vivo carotid images compared to reconstruction without known support.)
