Abstract

fetched live from OpenAlex

In this paper, a new adaptive method for Catmull-Clark subdivision is introduced. Adaptive subdivision refines specific areas of a model according to user or application needs. Naive adaptive subdivision algorithm changes the connectivity of the mesh, causing geometrical inconsistencies that alter the limit surface. Our method expands the specified region of the mesh such that when it is adaptively subdivided, it produces a smooth surface whose selected area is identical to when the entire mesh is refined. This technique also produces a surface with an increasing level of detail from coarse to fine areas of the surface. We compare our adaptive subdivision with other schemes and present some example applications.

Not calibrated prevalence, not ground truth. Human validation pending. The Gemma side is a direct model label for every work in the frame, read from the title-only record. The Codex side is a classifier learned from the 10,348 direct Codex labels and calibrated to design-weighted sample rates; fields without enough sample support carry no Codex call. Candidate is the union of the two sides; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human labels.

Machine scores (provisional)

The two teacher heads of the student model, read on this work. A score orders the frame for review; it never asserts a category, and the validation status ships verbatim with every row.

Baseline scores from an immature model (maturity gate not passed, 7 training rounds). Scores rank; they never assert a category.
