  1. Chii chaive chakakosha innovation yeDreamFusion (2022)?
    • Yakashandisa Score Distillation Sampling kugadzira 3D kubva ku2D diffusion modhi isina 3D yekudzidzisa data.
    • Yakanga iri yekutanga kuongorora zvinhu chaizvo neLiDAR
    • Yakadzidziswa yakananga pane yakakura yakanyorwa 3D mesh dataset
    • Yakagadzira 3D modhi ipapo ichishandisa imwechete yekupfuura
  2. Chii chinonzi 'Janus dambudziko' mune zvinyorwa-ku-3D?
    • Mienzaniso inopa zvishoma nezvishoma kuti ibatsire
    • Zvinhu zvinogadzirwa zvinoratidza zviso zvakawanda kana mativi kubva kumakona akasiyana
    • Mamiriro anoonekwa akashambidzwa uye grey
    • Iyo 3D faira fomati haienderane neinjini dzemitambo
  3. Ndeapi maviri aive OpenAI's ekutanga mavara-ku-3D ekufambisa-mberi mhando?
    • DALL-E uye CLIP
    • Stable Diffusion uye Midjourney
    • Point-E uye Shap-E
    • DreamFusion uye Magic3D
  4. Nei nzira dzekutanga dzekugadzirisa-dzakavakirwa senge DreamFusion dzainonoka?
    • Vaifanira kudhaunirodha mhando kubva mugore nguva yega yega
    • Ivo vakapa mu8K resolution nekusarudzika
    • Vaida kuveza nemaoko pakati pematanho
    • Ivo vakakwenenzvera yakaparadzana 3D inomiririra pachinhu chimwe pamusoro peakawanda kupa iterations
  5. Ndeipi fomati yekubuda HAIYO yakajairika 3D inomiririra inogadzirwa neaya masisitimu?
    • MP3 odhiyo waveform
    • Polygon mesh
    • Radiance field (NeRF)
    • Point cloud
  6. Chii chinonzi 'multi-view consistency' chinoreva dambudziko?
    • Kuita kuti saizi yefaira ienderane pane zvese zvinotengeswa kunze kwenyika
    • Kuve nechokwadi chekuti chinhu chinotaridzika chakabatana uye chakarurama kubva kune yega kamera angle
    • Kuchengeta chinyorwa chiri pasi pemuganho wemazwi
    • Kufananidza palette yeruvara negwara remhando
  7. What representation does Shap-E directly generate?
    • Only a fixed-resolution RGB image
    • A text transcript with speaker labels
    • Parameters of implicit functions that can render as textured meshes or neural radiance fields
    • A single unstructured audio waveform
  8. How does the Point-E paper’s two-stage system produce a 3D point cloud?
    • A 3D artist manually models every prompt
    • A NeRF is optimized from scratch using hundreds of camera views
    • A classifier predicts a file extension without generating geometry
    • A text-to-image model first generates a synthetic view, then an image-conditioned diffusion model produces a point cloud
