  1. What did Luma’s historical Dream Machine product generate?
    • Short video clips conditioned on text or image inputs
    • Three-dimensional CAD files from audio alone
    • A guarantee of realistic physics in every clip
    • Neural radiance fields from a single unposed image
  2. Which research approach reconstructs a 3D scene from images by representing it as a continuous radiance field?
    • CTC sequence alignment
    • Neural radiance fields (NeRF)
    • Region proposal networks
    • Повышение градиента
  3. Какова самая сложная техническая задача при создании видео, а не одного изображения?
    • Выбор шрифта
    • Сжатие одного JPEG
    • Поддержание временной согласованности между кадрами
    • Выбор доменного имени
  4. What did Luma introduce as Camera Motion Concepts for its Ray2 video model?
    • A guarantee that generated videos match real footage
    • A NeRF feature that requires no training examples
    • A rule that keeps every object fixed in every frame
    • Learnable camera moves that can be composed from one or a few examples
  5. What input does the original NeRF paper use to learn a radiance field for a scene?
    • Multiple posed images of the scene
    • A single text prompt with no images
    • An unordered list of object names
    • A video transcript with no camera information
  6. What does a NeRF query at a 3D location and viewing direction?
    • A tokenized transcript and speaker label
    • A color and volume density used for rendering
    • A camera-motion command and frame index
    • A bounding box and object class only
  7. Which video model does Luma’s July 2026 official information page identify as current?
    • Dream Machine, which remains the current model
    • Ray2, which is not deprecated
    • Ray3.2
    • NeRF, a product for text-to-video generation
  8. What should a user check before treating a generated clip as factual footage?
    • Whether the file uses a common codec
    • Whether it has a high frame rate
    • Whether it contains a title card
    • Whether the clip is synthetic and what prompt or source material produced it
