Abstract

fetched live from OpenAlex

3D sketches are an effective representation of a 3D shape, convenient to create via modern Virtual or Augmented Reality (VR/AR) interfaces or from 2D sketches. For 3D sketches drawn by designers, human observers can consistently imagine the surface they imply, yet reconstructing such a surface with modern methods remains an open problem. Existing methods either assume a clean, well-structured 3D curve network (while in reality most 3D sketches are rough and unstructured), or make no effort to produce a surface consistent with perceptual observations. We propose a novel method that addresses this challenge by designing a system that reconstructs a surface that better aligns with human perception from a clean or rough set of 3D sketches. As the topology of the desired surface is unknown, we use an implicit neural surface representation, parameterized via its gradient field.

Fetched live from OpenAlex and de-inverted. Abstracts are not stored in this database: the inverted indexes are 8.6 GB of the frame’s 9.3 GB of text, and the host has 13 GB free.

Full frame distilled prediction

Teacher imitation

Not calibrated prevalence, not ground truth. Human validation pending. Learned from the 10,348 direct Codex labels and 10,348 direct Gemma labels. Candidate is the union of thresholded teacher heads; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human labels or direct frontier model 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.
