The mathematical basis for Bézier curves—the Bernstein polynomials—was established in 1912, but the polynomials were not applied to graphics until some 50 years later when mathematician Paul de Casteljau in 1959 developed de Casteljau's algorithm, a numerically stable method for evaluating the curves, and became the first to apply them to computer-aided design at French automaker Citroën ...
The geometry of a single bicubic patch is thus completely defined by a set of 16 control points. These are typically linked up to form a B-spline surface in a similar way as Bézier curves are linked up to form a B-spline curve. Simpler Bézier surfaces are formed from biquadratic patches (m = n = 2), or Bézier triangles.
In the mathematical field of numerical analysis, De Casteljau's algorithm is a recursive method to evaluate polynomials in Bernstein form or Bézier curves, named after its inventor Paul de Casteljau. De Casteljau's algorithm can also be used to split a single Bézier curve into two Bézier curves at an arbitrary parameter value.
Béziergon – The red béziergon passes through the blue vertices, the green points are control points that determine the shape of the connecting Bézier curves. In geometric modelling and in computer graphics, a composite Bézier curve or Bézier spline is a spline made out of Bézier curves that is at least continuous. In other words, a ...
Bézier curve adjustment; Rectangle, ellipse, Bézier curve and B-spline creation tools. The text tool. Rectangle, ellipse, Bézier and B-spline masking tools (which define the part of an object that is visible).

SolveSpace is shipped with the following basic features: [12] [13] 2D sketch modeling SolveSpace supports parametric 2D drawing of lines, circles, arcs, cubic bézier curves etc; datum points and lines are also supported for general, reference based modeling.
For higher degrees of curve, P0 P1 and P2 aren't defined by the grey lines anymore- they're defined by a chain of parent functions that go all the way up to the grey lines through the same algorithm. So these intermediate line segments show how Bezier curves are algorithmically constructed, although mathematically the curve can still be ...
In the mathematical subfield of numerical analysis, de Boor's algorithm [1] is a polynomial-time and numerically stable algorithm for evaluating spline curves in B-spline form. It is a generalization of de Casteljau's algorithm for Bézier curves. The algorithm was devised by German-American mathematician Carl R. de Boor. Simplified ...
