Figure, table and section ledger

Editorial contribution type: Architecture & representation (primary).

Layout extraction, not a required paper template. Counts are distinct caption labels; a multi-panel figure counts once. Section spans are estimated from heading positions, including floats and whitespace. Method and limitations.

Extraction notes: No attached appendix boundary detected. Zero means no recognized caption, not independently verified absence.

Source-bound correction: All top-level main headings and the reference boundary checked against source PDF text; source-bound positions use physical single-column y/page-height, not a two-column reading-order surrogate. Running page-number/author titles, affiliations, numbered contribution bullets, footnotes and bibliography continuations are excluded. This linked manuscript contains no appended supplementary section; separate supplement links were not scanned.

Section-by-section lengths and source pages

The title/abstract/front matter precede the first numbered heading. A span ends at the next detected top-level heading, not at the last sentence; end-page whitespace is included. References and statements are listed separately. These are not measurements of text-only or artwork area.

    Argument and organization

    1. 1 Introduction; 2 Related Work

      Distinguishes geometric surface fidelity from artist-like triangle organization, explaining why a visually plausible dense surface is not the whole target.

    2. 3 Method: nearest-vertex field, flow matching, extraction and augmentation

      Defines the field before its generative model and extraction procedure, then evaluates geometry and topology with separate metrics and preferences.

    3. 4 Experiments and ablations; 5 Conclusion

      Evaluation separates Objaverse from generated out-of-distribution shapes and identifies model-judged versus human-judged topology and geometry preferences.

    Problem, claim and contribution

    Distinguishes geometric surface fidelity from artist-like triangle organization, explaining why a visually plausible dense surface is not the whole target.

    Abstract and Section 1, pp.1–3 · Main paper

    Argument and section order

    Defines the field before its generative model and extraction procedure, then evaluates geometry and topology with separate metrics and preferences.

    Sections 3–4, pp.4–14 · Main paper

    Figures, captions and visual explanation

    The three-part overview separates field encoding, conditional flow generation and mesh extraction. Qualitative comparisons use matched wireframe crops on in-domain and generated geometries.

    Figure 2, p.5; Figure 4, p.11 · Main paper

    Tables, comparisons and evidence

    Evaluation separates Objaverse from generated out-of-distribution shapes and identifies model-judged versus human-judged topology and geometry preferences.

    Tables 1–2 and Section 4.4, pp.10–12 · Main paper

    Appendix and reproducibility

    Augmentation field details, full training settings and extraction-parameter sensitivity are assigned to supplementary material; that separate source was not inspected.

    Sections 3.4 and 4.1–4.3, pp.9–10 · Main paper

    Clarity and writing conventions

    Method prose assigns each stage a distinct role and the limitations explicitly name voxelization as an obstacle to larger scenes.

    Section 3, pp.4–5; Limitations, p.14 · Main paper

    What to reuse—and what not to infer

    Transferable lesson: When generating a new representation, define it with a small local example, show conversion to the final artifact, and evaluate structure separately from appearance.

    Boundary: Perceptual VLM scores and human preferences are not the same metric; visual topology quality does not establish arbitrary mesh validity or large-scene scalability.

    Apply this lesson using the argument and evidence worksheet.
