在计算机图形学和可视化领域中，经常需要对具有大量多边形的多边形模型进行可视化。显示质量是强制性的，但是还期望具有快速更新显示的能力以便促进交互式使用。基于点的绘制方法已经被证明是有效的。在这个范例的基础上，我们引入了PMR系统，它使用了一个层次的点和三角形渲染。这种层次结构与现有方法中使用的层次结构根本不同。它基于对象空间中的特征几何，而不是其在屏幕空间中的投影。这提供了优于现有方法的某些优点。
Within the field of computer graphics and visualization, it is often necessary to visualize polygonal models with large number of polygons. Display quality is mandatory, but it is also desirable to have the ability to rapidly update the display in order to facilitate interactive use. Point based rendering methods have been shown effective for this task. Building on this paradigm we introduce the PMR system which uses a hierarchy both in points and triangles for rendering. This hierarchy is fundamentally different from the ones used in existing methods. It is based on the feature geometry in the object space rather than its projection in the screen space. This provides certain advantages over the existing methods.
