| Abstract |
We present a method for editing the LOD of quad meshes, which supports both adaptive refinement and adaptive coarsening. Starting at a base mesh, we generate a quad-dominant mesh which
is consistent with the Catmull-Clark subdivision. Consistency is both topological and geometrical:
an adaptively subdivided mesh coincides with the uniformly subdivided mesh wherever the level of
subdivision is uniform, and the limit surface is the same. Subdivided meshes contain a majority of
quad elements and a moderate amount of triangles and pentagons in the regions of transition across
different levels of detail. Topological LOD editing is controlled with local conforming operators, which
support both mesh refinement and mesh coarsening and work on a plain mesh without the need of
cumbersome hierarchical data structures.
