bezier surface ppt

, N, are the Bernstein polynomials of degree N, and t ϵ [0, 1]. A Bézier surface is defined by a two-dimensional set of control points p i,j, where i is in the range of 0 and m, and j is in the range of 0 and n.Thus, in this case, we have m+1 rows and n+1 columns of control points and the control point on the i-th row and j-th column is denoted by p i,j.Note that we have (m+1)(n+1) control points in total. In its unwound form, B-splines do not interpolate any of its control points, while the Bezier … II Surfaces 9 Tensor product surfaces 9.1 Tensor products 125 9.2 Tensor product B´ezier surfaces 127 9.3 Tensor product polar forms 130 9.4 Conversion to and from monomial form 131 9.5 The de Casteljau algorithm 132 9.6 Derivatives 133 9.7 Simple Cr joints 135 Surfaces The curves come close to, but may not actually pass through, the control points.
