This a small continuation of a series on parallelism and Open CASCADE started last year. This post is just about a particular class but it is fundamental enough deserving a separate mention.Geom_BSplineCurve, Geom_BSplineSurface, Geom2d_BSplineCurve, Geom_BezierCurve, Geom_BezierSurface, Geom2d_BezierCurve. They implement B-Spline and Bezier curves and surface.Supposedly for optimization of calculation of points and derivatives, they use a cache that stores information used in calculation...
