Description: 用Phong光照明模型显示网格模型(*.smf)。
分别实现不使用/使用增量式法向插值算法，比较两种不同的显示效果
Phong模型中各参数可调，观察它们的作用；
选做：用光线跟踪算法实现简单场景的绘制。该场景由三堵互相垂直的墙和几个球所组成(墙和球表面性质、光源等参数自定)。-With the Phong lighting model shows the grid model (*. smf). Respectively, will not be used/use an incremental method to the interpolation algorithm to compare two different types of display Phong model with adjustable parameters to observe their role elected to do: The ray tracing algorithm is simple rendering scenarios. The scenario consists of three block walls perpendicular to each other and a few balls of the composition (wall and the ball surface properties, light source parameters, such as self-be).

Description: 医学图像配准，医学图像2D_3D配准，基于vc++开发。-Abstract. We present a method that performs the rigid 2D/3D image registration
efficiently on the GPU. As one main contribution of this paper, we propose an
efficient method for generating realistic DRRs that are visually similar to X-ray
images. Therefore, we model some of the electronic post-processes of current X-
ray C-arm-systems. As another main contribution, the GPU is used to compute
eight intensity-based similarity measures between the DRR and the X-ray image
in parallel. A combination of these eight similarity measures is used as a new
similarity measure for the optimization. We evaluated the performance and the
precision of our 2D/3D image registration algorithm using two phantom models.
Compared to a CPU+GPU algorithm, which calculates the similarity measures
on the CPU, our GPU algorithm is between three and six times faster. In contrast
to single similarity measures, our new similarity measure achieved precise and
robust registration results for both phantom m
