—We present a method to produce a hierarchy of triangle meshes that can be used to blend different levels of detail in a smooth fashion. The algorithm produces a sequence of meshes 0 0 , 0 1 , 0 2 , ..., 0 n , where each mesh 0 i can be transformed to mesh 0 i+1 through a set of triangle-collapse operations. For each triangle, a function is generated that… (More)

We present a new method to produce a hierarchical set of triangle. meshes that can be used to blend different levels of detail in a smooth fashion. The algorithm produces a sequence of meshes MO, Ml, M2,. .. . M,, where each mesh Mi can be transformed to mesh Mt.+1 through a set of triangle-collapse operations. For each triangle , a fin&on is generated that… (More)
