• CEI-3D uses a collaborative explicit-implicit reconstruction approach, representing objects with an implicit SDF network and differentially sampled handler points.method 95%
• The implicit network in CEI-3D provides a smooth and continuous geometry prior.technical 90%
• Explicit handler points in CEI-3D offer localized control, enabling mutual guidance between the global 3D structure and user-specified local editing regions.technical 90%
• CEI-3D includes a physical properties disentangling module to decouple the color of handler points into separate physical properties.method 90%
• A dual-diffuse-albedo network in CEI-3D processes edited and non-edited regions separately to prevent interference from editing operations.method 90%
• CEI-3D incorporates a spatial-aware editing module that enables part-wise adjustment of relevant handler points using a cross-view propagation-based 3D segmentation strategy.method 90%
• CEI-3D achieves more realistic and fine-grained editing results than state-of-the-art methods while requiring less editing time.result 95%
