Majibu na maelezo huonekana unapojibu maswali.

  1. Je, kipengele cha kukokotoa umbali kilichotiwa saini kinarudisha nini kwa nukta fulani ya 3D?
    • Umbali wa eneo la karibu zaidi, na ishara ya ndani/nje
    • Rangi ya uso katika hatua hiyo
    • Idadi ya pembetatu karibu na hatua hiyo
    • Mwangaza wa eneo hilo
  2. Sehemu halisi ya SDF iko wapi?
    • Ambapo kipengele cha kukokotoa kimekuzwa zaidi
    • Katika seti ya kiwango cha sifuri (umbali ni sawa na sifuri)
    • Ambapo ishara ni nzuri kila wakati
    • Katikati ya sanduku la kufunga
  3. Where does a true signed distance function satisfy the unit-gradient eikonal condition?
    • At every point, including all nonsmooth points
    • Only at the zero level set
    • At differentiable points, which is almost everywhere for common surfaces
    • Only outside the shape
  4. Ufuatiliaji wa tufe hutumiaje thamani ya SDF?
    • Daima hatua kwa kiasi kidogo fasta
    • Inarudi nyuma ili kuzuia uso
    • Inapuuza SDF na sampuli nasibu
    • Inasonga mbele kwa thamani ya SDF, umbali salama kwa uso wa karibu zaidi
  5. Je, DeepSDF hutumia nini kuwakilisha umbo maalum?
    • Nambari fupi iliyofichika inayoingizwa kwenye mtandao wa neva
    • Wavu kamili wa pembetatu iliyohifadhiwa kwenye kumbukumbu
    • Picha moja ya RGB
    • Orodha ya nafasi za kamera
  6. What is one useful property of an SDF representation compared with a fixed triangle mesh?
    • It guarantees exact geometry regardless of training data or sampling
    • It is a continuous function that can be queried at chosen resolutions, subject to representation accuracy and compute
    • It always uses less memory than every possible mesh
    • It eliminates the need to compute surface normals
  7. How can a signed distance function support robot collision checking?
    • It identifies the material composition of each obstacle
    • It predicts the robot's battery life from its pose
    • It gives a distance to nearby surfaces that can help determine clearance from obstacles
    • It converts a robot path into a camera image
  8. In the NeuS reconstruction method, what representation is learned for a scene surface?
    • A fixed list of RGB colors with no geometry
    • An unordered set of camera exposure settings
    • A text caption for each image without a 3D representation
    • The surface is represented as the zero-level set of a neural signed distance function
