摘　　要：一个网格模型的多分辨率表示由原模型信息与附加的多分辨率信息组成,由于两者独立存储,所以每次使用一个模型的多分辨率表示时,必须由原模型重新生成。给出了一种网格的多分辨率表示,支持模型渐渐简化、渐进细化及渐渐传输。还给出了这种多分辨率表示的构造方法,通过重新排序网格的三角形表与顶点表的元素,将所有多分辨率信息熔入三角形表之中(称为“多分辨率三角形表”)。由于没有增加任何额外变量,“多分辨率三角形表”仍是原网格的三角形表,一旦被生成后,可以被直接反复地使用。As the original mesh information and its multi-resolution information are stored separately, the multi-resolution mesh representation can be used only when created each time. A multi-resolution mesh representation was proposed based on “triangle contraction”simplification operation and “triangle split” refinement operation, which supports mesh progressive simplification, refinement and transmission, and a generation approach to the multi-resolution mesh representation was proposed. The multi-resolution representation is as simple as the original model, so it can be used directly and repeatedly when created once.
