Cubic Spline In numerical analysis, a cubic Hermite spline or cubic Hermite interpolator is a spline where each piece is a thirddegree polynomial specified in Hermite form:[1] that is, by its values and first derivatives at the end points of the corresponding domain interval. Cubic Hermite splines are typically used for interpolation of numeric data specified at given argument values x 1 , x 2 , … , x n displaystyle x_ 1 ,x_ 2 ,ldots ,x_ n , to obtain a smooth continuous function. The data should consist of the desired function value and derivative at each x k displaystyle x_ k [...More...]  "Cubic Spline" on: Wikipedia Yahoo Parouse 

Hermite Polynomial In mathematics, the Hermite polynomials Hermite polynomials are a classical orthogonal polynomial sequence. The polynomials arise in:probability, such as the Edgeworth series; in combinatorics, as an example of an Appell sequence, obeying the umbral calculus; in numerical analysis as Gaussian quadrature; in physics, where they give rise to the eigenstates of the quantum harmonic oscillator; in systems theory in connection with nonlinear operations on Gaussian noise. in random matrix theory in Wigner–Dyson ensembles.

Key Frame A keyframe in animation and filmmaking is a drawing that defines the starting and ending points of any smooth transition. The drawings are called "frames" because their position in time is measured in frames on a strip of film. A sequence of keyframes defines which movement the viewer will see, whereas the position of the keyframes on the film, video, or animation defines the timing of the movement. Because only two or three keyframes over the span of a second do not create the illusion of movement, the remaining frames are filled with inbetweens.Contents1 Use of keyframes as a means to change parameters 2 Video editing 3 Video compression 4 See also 5 ReferencesUse of keyframes as a means to change parameters[edit] In software packages that support animation, especially 3D graphics, there are many parameters that can be changed for any one object.

Kochanek–Bartels Spline In mathematics, a Kochanek–Bartels spline Kochanek–Bartels spline or Kochanek–Bartels curve is a cubic Hermite spline with tension, bias, and continuity parameters defined to change the behavior of the tangents.

Monotone Cubic Interpolation In the mathematical subfield of numerical analysis, monotone cubic interpolation is a variant of cubic interpolation that preserves monotonicity of the data set being interpolated. Monotonicity is preserved by linear interpolation but not guaranteed by cubic interpolation.Contents1 Monotone cubic Hermite interpolation1.1 Interpolant selection 1.2 Cubic interpolation2 Example implementation 3 References 4 External linksMonotone cubic Hermite interpolation[edit]Example showing nonmonotone cubic interpolation (in red) and monotone cubic interpolation (in blue) of a monotone data set.Monotone interpolation can be accomplished using cubic Hermite spline with the tangents m i displaystyle m_ i modified to ensure the monotonicity of the resulting Hermite spline.

Monotonic Function In mathematics, a monotonic function[1] [2](or monotone function[3]) is a function between ordered sets that preserves or reverses the given order.

Numerical Analysis Numerical analysis Numerical analysis is the study of algorithms that use numerical approximation (as opposed to general symbolic manipulations) for the problems of mathematical analysis (as distinguished from discrete mathematics). One of the earliest mathematical writings is a Babylonian tablet from the Yale Babylonian Collection Yale Babylonian Collection (YBC 7289), which gives a sexagesimal numerical approximation of the square root of 2, the length of the diagonal in a unit square. Being able to compute the sides of a triangle (and hence, being able to compute square roots) is extremely important, for instance, in astronomy, carpentry and construction.[2] Numerical analysis Numerical analysis continues this long tradition of practical mathematical calculations [...More...]  "Numerical Analysis" on: Wikipedia Yahoo Parouse 

Tricubic Interpolation In the mathematical subfield numerical analysis, tricubic interpolation is a method for obtaining values at arbitrary points in 3D space of a function defined on a regular grid.

Hermite Interpolation In numerical analysis, Hermite interpolation, named after Charles Hermite, is a method of interpolating data points as a polynomial function. The generated Hermite interpolating polynomial is closely related to the Newton polynomial, in that both are derived from the calculation of divided differences. However, the Hermite interpolating polynomial may also be computed without using divided differences, see Chinese remainder theorem § Hermite interpolation. Unlike Newton interpolation, Hermite interpolation matches an unknown function both in observed value, and the observed value of its first m derivatives [...More...]  "Hermite Interpolation" on: Wikipedia Yahoo Parouse
