  2. B-spline - Wikipedia

    en.wikipedia.org/wiki/B-spline

    Spline curve drawn as a weighted sum of B-splines with control points/control polygon, and marked component curves. In the mathematical subfield of numerical analysis, a B-spline or basis spline is a spline function that has minimal support with respect to a given degree, smoothness, and domain partition.

  3. Spline (mathematics) - Wikipedia

    en.wikipedia.org/wiki/Spline_(mathematics)

    Spline (mathematics) For the drafting tool, see Flat spline. Single knots at 1/3 and 2/3 establish a spline of three cubic polynomials meeting with C2 parametric continuity. Triple knots at both ends of the interval ensure that the curve interpolates the end points. In mathematics, a spline is a function defined piecewise by polynomials.

  4. Spline wavelet - Wikipedia

    en.wikipedia.org/wiki/Spline_wavelet

    In the mathematical theory of wavelets, a spline wavelet is a wavelet constructed using a spline function. [1] There are different types of spline wavelets. The interpolatory spline wavelets introduced by C.K. Chui and J.Z. Wang are based on a certain spline interpolation formula. [2] Though these wavelets are orthogonal, they do not have ...

  5. Bézier curve - Wikipedia

    en.wikipedia.org/wiki/Bézier_curve

    A Bézier curve is defined by a set of control points P0 through Pn, where n is called the order of the curve (n = 1 for linear, 2 for quadratic, 3 for cubic, etc.). The first and last control points are always the endpoints of the curve; however, the intermediate control points generally do not lie on the curve.

  6. Spline interpolation - Wikipedia

    en.wikipedia.org/wiki/Spline_interpolation

    Spline interpolation. In the mathematical field of numerical analysis, spline interpolation is a form of interpolation where the interpolant is a special type of piecewise polynomial called a spline. That is, instead of fitting a single, high-degree polynomial to all of the values at once, spline interpolation fits low-degree polynomials to ...

  7. Non-uniform rational B-spline - Wikipedia

    en.wikipedia.org/wiki/Non-uniform_rational_B-spline

    Non-uniform rational basis spline (NURBS) is a mathematical model using basis splines (B-splines) that is commonly used in computer graphics for representing curves and surfaces. It offers great flexibility and precision for handling both analytic (defined by common mathematical formulae) and modeled shapes. It is a type of curve modeling, as ...

  8. Boundary representation - Wikipedia

    en.wikipedia.org/wiki/Boundary_representation

    ISO 10303-511 Topologically bounded surface, definition of an advanced face, that is a bounded surface where the surface is of type elementary (plane, cylindrical, conical, spherical or toroidal), or a swept surface, or B-spline surface. The boundaries are defined by lines, conics, polylines, surface curves, or b spline curves

  9. De Boor's algorithm - Wikipedia

    en.wikipedia.org/wiki/De_Boor's_algorithm

    De Boor's algorithm. 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.
