What is Text-to-3D Generation?
Ọgbọ ederede gaa na 3D na-atụgharị ngwa ngwa edere dị ka 'oche akpụkpọ anụ vintage' ka ọ bụrụ ihe ngosi 3D zuru oke ị nwere ike ịtụgharị, ọkụ, ma tinye n'ime egwuregwu ma ọ bụ ọnọdụ. Ọ na-ekwe nkwa ime maka akụ 3D ihe ndị na-emepụta ihe oyiyi mere maka foto.
Kedu ihe bụ isi ihe ọhụrụ nke DreamFusion (2022)?
DreamFusion kwalitere NeRF nke mere na nlele 2D ọ bụla egosipụtara nwere afọ ojuju ụdị mgbasa ozi 2D jụrụ oyi, na-eji SDS na achọghị data ọzụzụ 3D.
Kedu ihe bụ nsogbu Janus na ederede-gaa-3D?
Akpọrọ aha chi ndị Rom nwere ihu abụọ, nsogbu Janus bụ mgbe ihe na-etolitekwu ihu n'ihi na a na-emezi echiche 2D ọ bụla n'onwe ya.
Kedu ụzọ m ga-esi bụrụ ụdị mbugharị ndepụta nke OpenAI?
