ABSTRACT
OCME (Out-of-Core Mesh Editing) comprises a novel data structure and related algorithms for out-of-core editing of large meshes. It inserts triangles into a hashed multigrid on the basis of their size and position. This allows rapid access and, on average, a constant construction time per triangle. Unlike previous approaches, OCME maintains no explicit hierarchy, so inserting, modifying, or deleting data doesn't require costly refitting. OCME stores attributes locally; for example, you can assign a vertex color to only small parts of the dataset. It also naturally handles multiple-scale datasets.
