De Casteljau's Algorithm - Definition

Definition

A Bezier curve B (of degree n) can be written in Bernstein form as follows

,

where b is a Bernstein basis polynomial

.

The curve at point t0 can be evaluated with the recurrence relation

Then, the evaluation of at point can be evaluated in steps of the algorithm. The result is given by :

Moreover, the Bézier curve can be split at point into two curves with respective control points :

Famous quotes containing the word definition:

    It’s a rare parent who can see his or her child clearly and objectively. At a school board meeting I attended . . . the only definition of a gifted child on which everyone in the audience could agree was “mine.”
    Jane Adams (20th century)

    Although there is no universal agreement as to a definition of life, its biological manifestations are generally considered to be organization, metabolism, growth, irritability, adaptation, and reproduction.
    The Columbia Encyclopedia, Fifth Edition, the first sentence of the article on “life” (based on wording in the First Edition, 1935)

    The man who knows governments most completely is he who troubles himself least about a definition which shall give their essence. Enjoying an intimate acquaintance with all their particularities in turn, he would naturally regard an abstract conception in which these were unified as a thing more misleading than enlightening.
    William James (1842–1910)
