Bézier Form of S-Patches
 Kolcun, Alexej
In this paper the main properties for the biquadratic case of S-patches are described. Bézier form of patches is used. It gives us the possibility to find the correlation between triangular and quadrilateral patches. Condition for smooth concatenation of biquadratic BS-patches is formulated.

Biquadratic S-Patch in Bézier form
 Kolcun, Alexej
Mutual conversions between triangular and quadrilateral meshes need the same degree of both diagonal and boundary curves of quadrilateral meshes. New approach to quadrilateral patches, S-Patches, offers such possibility. The Bézier approach of Smart patches (S-Patch) in the biquadratic case is analyzed. Dependencies among the control points are derived. BS-Patches are presented. Close relation between Bézier triangles and BSPatches is found. Condition for smooth concatenation of biquadratic BS-Patches is formulated.
