Due to the implicit manner to use features for shape representation, manipulating the shapes faces in herent challenge of inconvenience, since the feature cannot be intuitively edited. In this work, we propose neural generalized cylinder (NGC) for ex plicit manipulation of NSDF, which is an extension of traditional generali zed cylinder (GC). Specifically, we define a central curve first and assig n neural features along the curve to represent the profiles. Then NSDF is defined on the relative coordinates of a specialized GC with oval-shaped p rofiles. By using the relative coordinates, NSDF can be explicitly control led via manipulation of the GC. To this end, we apply NGCto many non-rigid deformation tasks like complex curved deformation, local scaling and twis ting for shapes. The comparison on shape deformation with other methods pr oves the effectiveness and efficiency of NGC. Furthermore, NGC could utili ze the neural feature for shape blending by a simple neural feature interp olation.\n\nRegistration Category: Full Access, Full Access Supporter\n\nL anguage Format: English Language\n\nSession Chair: Noam Aigerman (Universi ty of Montreal) URL:https://asia.siggraph.org/2024/program/?id=papers_509&sess=sess130 END:VEVENT END:VCALENDAR
