Approximation of a given surface by such a mesh needs to consider the visual appearance, ap proximation quality, the position and orientation of circular intersection s of neighboring faces and the existence of a torsion free support structu re that is formed by the planes of circular edges. The latter requirement implies that the mesh simultaneously defines a second mesh whose faces lie on the same spheres as the faces of the first mesh. It is a discretizatio n of the two envelopes of a sphere congruence, i.e., a two-parameter famil y of spheres. We relate such sphere congruences to torsal parameterization s of associated line congruences. Turning practical requirements into prop erties of such a line congruence, we optimize line and sphere congruence a s a basis for computing a mesh with spherical triangular or quadrilateral faces that approximates a given reference surface.\n\nRegistration Categor y: Full Access, Full Access Supporter\n\nLanguage Format: English Language \n\nSession Chair: Haisen Zhao (Shandong University) URL:https://asia.siggraph.org/2024/program/?id=papers_591&sess=sess109 END:VEVENT END:VCALENDAR
