The key insight is to incorporate an implicit\nsigned distance field (SDF) within 3D Gaus sians for surface modeling and to\nenable the alignment and joint optimiza tion of both SDF and 3D Gaussians.\nTo achieve this, we design coupling st rategies that align and associate the\nSDF with 3D Gaussians, allowing for unified optimization and enforcing\nsurface constraints on the 3D Gaussia ns. With alignment, optimizing the 3D\nGaussians provides supervisory sign als for SDF learning, enabling the recon-\nstruction of intricate details. However, this only offers sparse supervisory\nsignals to the SDF at locat ions occupied by Gaussians, which is insufficient\nfor learning a continuo us SDF. Then, to address this limitation, we incor-\nporate volumetric ren dering and align the rendered geometric attributes\n(depth, normal) with t hat derived from 3DGS. In sum, these two designs\nallow SDF and 3DGS to be aligned, jointly optimized, and mutually boosted.\nOur extensive experime ntal results demonstrate that our 3DGSR enables\nhigh-quality 3D surface r econstruction while preserving the efficiency and\nrendering quality of 3D GS. Besides, our method competes favorably with\nleading surface reconstru ction techniques while offering a more efficient\nlearning process and muc h better rendering qualities.\n\nRegistration Category: Full Access, Full Access Supporter\n\nLanguage Format: English Language\n\nSession Chair: Pe ng-Shuai Wang (Peking University) URL:https://asia.siggraph.org/2024/program/?id=papers_678&sess=sess115 END:VEVENT END:VCALENDAR
