Q1 multiple-choice · approaches Which approach to 3D from PhotoRobot imagery is photogrammetry’s primary mechanism?
Source: SP3D01 §1.
Explanation: Photogrammetry = many overlapping images + feature triangulation. Depth-fusion + hybrid are alternatives. PhotoRobot ships photogrammetry-optimized pipelines.
Q2 scenario · reflective Customer wants 3D of luxury watches (polished chrome + glass face).
Source: SP3D01 §1.
Explanation: Reflective + transparent = photogrammetry struggles. Hybrid handles these surfaces; depth-fusion alone has lower texture quality.
Q3 multiple-choice · formats For cross-platform mobile AR (iOS + Android + web), what’s the standard delivery?
Source: SP3D01 §2.
Explanation: GLB for Android + web; USDZ for iOS AR Quick Look. <model-viewer> picks correct format per device.
Q4 scenario · overkill B2B distributor with 50,000 industrial fasteners, textual-buyer audience. Wants 3D for all.
Source: SP3D01 §4.
Explanation: Overkill signals: textual buyer audience + high volume + low-margin SKUs. 360° viewer delivers same engagement value at fraction of cost.
Q5 scenario · underkill Customer wants AR try-on for shoes. Plans 5k polycount per shoe.
Source: SP3D01 §5.
Explanation: Try-on AR needs accurate geometry. 5k = visible polygon edges; 15-25k is appropriate for fashion footwear AR.
Q6 multiple-choice · quality-dimensions What are the four main 3D model quality dimensions that trade off?
Source: SP3D01 §3.
Explanation: Multi-dimensional quality. Specialist tunes all four per use case.
Q7 true-false · photorobot-role PhotoRobot ships its own reconstruction engine alongside capture hardware.
Source: SP3D01 §7.
Explanation: PhotoRobot ships capture-first pipelines. Reconstruction is third-party (Reality Capture, Metashape, PaaS). Specialist bridges capture + third-party + delivery.
Q8 scenario · format-selection Customer wants 3D model handed to their internal 3D artist for further editing.
Source: SP3D01 §2.
Explanation: OBJ + FBX are 3D artist interchange formats. GLB/USDZ are delivery formats, not authoring formats.
Q9 multiple-choice · pbr Customer complains “the 3D model looks plastic, not like the real product.” Most likely cause?
Source: SP3D01 §3.
Explanation: “Plastic appearance” is almost always PBR material setup issue. Geometry can be perfect; material maps make it look real.
Q10 multiple-choice · customer-translation Customer says “we need 3D for our website.” What’s the Specialist’s first move?
Source: SP3D01 §1 + §4-5.
Explanation: Specialist translates ambiguous brief into specific architecture. Diagnostic questions first; commitment second.
