Q1 multiple-choice · pillars The 3 QC pillars for reconstructed 3D models?
Source: SP3D03 §2.
Explanation: Silhouette (does it look right) + material (does it feel right) + scale (does it measure right) = the three dimensions of QC.
Q2 scenario · thin-geometry Reconstruction missing the thin handle of a coffee cup. Right diagnosis?
Source: SP3D03 §4.
Explanation: Thin geometry is photogrammetry’s known limitation. Diagnose the cause; pick fix option appropriately.
Q3 multiple-choice · tool-selection Customer engagement: 50 SKUs/year, new to 3D, low setup budget. Recommended approach?
Source: SP3D03 §1.
Explanation: Low volume + low setup = PaaS. Per-model pricing makes sense; no infrastructure investment needed.
Q4 multiple-choice · scale-drift Model exports as GLB at 30 cm correctly; USDZ exports the same model as 30 m. Cause?
Source: SP3D03 §4.
Explanation: Scale drift across formats is common conversion issue. Verify per format; use authoritative conversion tools.
Q5 true-false · plastic-appearance When customer says “the model looks plastic,” the problem is usually mesh geometry.
Source: SP3D03 §4.
Explanation: “Plastic” is almost always PBR material setup (missing or wrong normal/metallic/roughness maps). Geometry can be perfect.
Q6 multiple-choice · iteration Typical iteration count for hero products vs commodity products?
Source: SP3D03 §5.
Explanation: Iteration count scales with quality bar + budget. Hero gets more iteration; commodity accepts first/second pass.
Q7 scenario · systematic-issue QC finds the same scale drift issue across 10+ products from same batch.
Source: SP3D03 §5.
Explanation: Systematic issue = pipeline problem, not per-model. Fix the system; don’t iterate symptoms.
Q8 multiple-choice · sample-qc For high-volume engagement (1000+ models/year), what’s the QC discipline?
Source: SP3D03 §6.
Explanation: Per-model QC doesn’t scale beyond ~50 models/week. Sample strategy catches systematic issues + drift.
Q9 multiple-choice · tolerance-bands Right scale tolerance for hero product vs bulk catalog product?
Source: SP3D03 §2.
Explanation: Tolerance scales with quality bar. Set explicitly per engagement; commit only to what budget supports.
Q10 multiple-choice · communication QC finding requires fixes in capture team’s discipline. Right communication?
Source: SP3D03 §7.
Explanation: Upstream communication is specific. Vague feedback (“captures are bad”) doesn’t help; specific symptom + remedy does.
