Generating B-spline curves with points, normals and curvature constraints: A constructive approach
No full textThis paper presents a constructive method for generating a uniform cubic B-spline curve interpolating a set of data points simultaneously controlled by normal and curvature constraints. By comparison, currently published methods have addressed one or two of those constraints (point, normal or cross-curvature interpolation), but not all three constraints simultaneously with C2 continuity. Combining these constraints provides better control of the generated curve in particular for feature curves on free-form surfaces. Our approach is local and provides exact interpolation of these constraints. © Springer-Verlag 2010.CATMULL E, 1978, COMPUT AIDED DESIGN, V10, P350, DOI 10.1016-0010-4485(78)90110-0; Farin G., 2002, CURVES SURFACES COMP; GOFUKU S, 2009, COMPUT AIDED DES; Halstead M., 1993, SIGGRAPH 93 C P, P35; Hoschek J., 1993, FUNDAMENTALS COMPUTE; Hoschek J, 1999, SHAPE PRESERVING REPRESENTATIONS IN COMPUTER-AIDED GEOMETRIC DESIGN, P163; Ye XZ, 1996, COMPUT AIDED DESIGN, V28, P741, DOI 10.1016-0010-4485(95)00080-1; Maekawa T, 2007, COMPUT AIDED DESIGN, V39, P313, DOI 10.1016-j.cad.2006.12.008; NASRI A, 2003, PACIFIC GRAPHICS; NASRI A, 2006, COMPUTER GRAPHICS IN, P761; Nasri AH, 2002, VISUAL COMPUT, V18, P259, DOI 10.1007-s003710100154; Nasri AH, 2002, VISUAL COMPUT, V18, P382, DOI 10.1007-s003710100155; Nasri AH, 2002, COMPUT GRAPH-UK, V26, P393, DOI 10.1016-S0097-8493(02)00082-1; Piegl L., 1997, NURBS BOOK; Prautzsch H., 2002, BEZIER B SPLINE TECH; SCHAEFER S, 2004, S GEOM PROC, P105; Weiss V, 2002, COMPUT AIDED GEOM D, V19, P19, DOI 10.1016-S0167-8396(01)00086-355
Interpolating multiple intersecting curves using catmull-clark subdivision surfaces
No full textThe problem of constructing a smooth subdivision surface interpolating multiple intersecting curves was partially addressed in the literature. In the context of Doo-Sabin subdivision surfaces, Nasri[3] presented a solution to interpolate unlimited number of curves through an extraordinary point. In the Catmull-Clark setting, no more than two intersecting curves could so far be interpolated. That is, the interpolation of multiple intersecting curves remains a non-trivial and elusive problem. This paper puts forth a solution to this problem. The solution relies in a fundamental way on the by-now well-known notion of Catmull-Clark Polygonal Complexes introduced in [5].

Nasri Khattar a modernist typotect
No full textLebanese architect-typographer Nasri Khattar was motivated by the postcolonial project of modernity. As part of the 1930s language and script reform project in Cairo, he focused on the technological and aesthetic reform of Arabic script. With a reduced set of 30 Unified Arabic letters, he strove to democratise knowledge, making reading Arabic easier to learn, and the production and typesetting of Arabic texts more efficient. This monograph presents his life's work, placing it within the context of the Arabic alphabet's history and typographic evolutio
