摘　　要：随着移动设备性能的逐渐提高,越来越多的图形渲染技术由普通PC移植到了移动平台,但移动设备的计算能力与PC相比依然存在较大差距。对于PC上能够渲染的复杂网格模型,需要进行简化后才能够在移动设备上渲染,而网格简化必然会导致模型的走样。虽然Phong着色可以实现大部分正向面的平滑效果,但是未能解决轮廓部分的不连续性。为了解决这个问题,利用一种基于顶点着色器的实时细化方法,在移动设备上实现了Phong Tessellation,达到了模型轮廓部分细化的目的。As the performance of mobile devices increases gradually, many rendering technologies are ported from PC to mobile platform. However, the performance of mobile device is still far behind PC. A complex mesh model which can be rendered in PC may need to be simplified before being rendered on the mobile device. And the simplification may lead to artifacts. Although most of the artifacts can be fixed by Phong Shading using normal interpolation, some artifacts still remain on interior contours and silhouettes if the surface geometry is not smooth. In order to solve this problem, the Phong Tessellation on mobile platform was implemented by utilizing a real-time tessellation method based on vertex shade, which can efficiently fix the artifacts on the contours.
