Our method is learning-free and carefully designed to maximize the use of GPU paralleli zation. The recent surge of implicit neural representations has led to sig nificant attention to occupancy fields, resulting in a wide range of 3D re construction and generation methods based on them. However, the outputs of such methods have been underestimated due to the bottleneck in converting the resulting occupancy function to a mesh. Marching Cubes tends to produ ce staircase-like artifacts, and most subsequent works focusing on exploit ing signed distance functions as input also yield suboptimal results for o ccupancy functions. Based on Manifold Dual Contouring (MDC), we propose Oc cupancy-Based Dual Contouring (ODC), which mainly modifies the computation of grid edge points (1D points) and grid cell points (3D points) to not u se any distance information. We introduce auxiliary 2D points that are use d to compute local surface normals along with the 1D points, helping ident ify 3D points via the quadric error function. To search the 1D, 2D, and 3D points, we develop fast algorithms that are parallelizable across all gri d edges, faces, and cells. Our experiments with several 3D neural generati ve models and a 3D mesh dataset demonstrate that our method achieves the b est fidelity compared to prior works.\n\nRegistration Category: Full Acces s, Full Access Supporter\n\nLanguage Format: English Language\n\nSession C hair: Hao (Richard) Zhang (Simon Fraser University, Amazon) URL:https://asia.siggraph.org/2024/program/?id=papers_267&sess=sess145 END:VEVENT END:VCALENDAR
