Add Lyria/Suno/Udio for music and ElevenLabs SFX and you finally have a unified workflow. This deep dive maps it in 14 chapters.

Sora 2가 정식 출시되고, Google Veo 3는 합성 오디오와 대화까지 만들고, Kling 2는 중국발 최강 영상 모델로 자리잡고, HunyuanVideo가 오픈웨이트 경쟁자를 처음으로 만들었다. 2026년 5월 시점의 AI 비디오 생성 지형도 — 폐쇄형 / 오픈웨이트 / 오디오·음악 결합 / 한국·일본 연구까지 14개 장으로 정리.

By 2026, a hundred photos and a desktop are enough to bake photorealistic 3D. This guide walks the entire 3DGS + photogrammetry stack: Nerfstudio 1.4 with Splatfacto, Postshot 2.0, Luma Genie 2, Polycam, Apple Object Capture on macOS Sequoia, the now-free RealityCapture 1.5, Scaniverse 4, and Meshroom — from capture to web viewer in one breath.

Nerfstudio 1.x의 Splatfacto, Postshot의 .ksplat, Luma Genie의 텍스트-투-3D, Polycam의 LiDAR 캡처, Apple Object Capture의 macOS Sequoia API, 무료가 된 RealityCapture 1.5, Scaniverse 4, Meshroom — 캡처에서 웹 뷰어까지 한 호흡으로 정리한다.
