Quiz IA et 3D

Les réponses et les explications apparaissent au fur et à mesure que vous répondez au quiz.

1. Un développeur de jeux reçoit de nouvelles vues convaincantes d’une chaise. Quel livrable requis doit encore être vérifié ?
   • Editable geometry, materials, scale and collision behavior in the export
   • A guarantee based solely on the nicest preview image
   • An assumption that hidden surfaces were measured directly
   • Proof of dimensions inferred from realistic lighting
2. Comment le guide caractérise-t-il une représentation de style NeRF ?
   • A guaranteed manufacturing model with exact dimensions
   • A spreadsheet of camera settings
   • A scene representation for synthesizing views, not automatically a production-ready mesh
   • A point cloud with connected faces
3. Une chaise générée semble correcte de face. De quel contrôle supplémentaire une application interactive a-t-elle besoin ?
   • Use only the front preview as acceptance evidence
   • Rotate or deform the asset and inspect whether it still works
   • Treat the first rendered image as its collision geometry
   • Approve physical measurements from the image alone
4. Pourquoi la reconstruction peut-elle être ambiguë à certains égards ?
   • Every surface is measured directly
   • The camera information is always exact
   • A rendered view reveals all unseen geometry
   • Hidden surfaces and reflective materials may not provide clear observations
5. Comment une équipe doit-elle choisir entre une représentation maillée, un nuage de points ou une représentation par synthèse de vues ?
   • Choose the representation that fits the intended application
   • Choose whichever renders best from one angle
   • Always use the largest file
   • Use the same representation for every task
6. What should be checked before using a generated asset in a game?
   • Only the preview image
   • Only the model’s confidence score
   • Scale, topology, materials, collision behavior, and export compatibility
   • Whether the asset uses a common name
7. Does high-quality view synthesis establish precise physical measurements?
   • Yes, because visual realism is a dimensional calibration
   • No; convincing appearance and geometric accuracy are different objectives
   • Yes, if the render has enough pixels
   • Only the file name needs to contain measurement units
8. Which export details help preserve a reproducible workflow?
   • Only a screenshot of the final render
   • The prompt alone
   • A confidence label without input records
   • Units, coordinate systems, texture paths, and source provenance
