AI & 3D Quiz

Answers and explanations appear as you take the quiz.

1. A game developer receives convincing new views of a chair. Which required deliverable still needs verification?
   • 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. How does the guide characterize a NeRF-style representation?
   • 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. A generated chair looks correct from the front. Which additional check does an interactive application need?
   • 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. Why can reconstruction be ambiguous from a few views?
   • 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. How should a team choose among a mesh, point cloud, or view-synthesis representation?
   • 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
