An
InterpolationAlgorithm for performing linear interpolation.方法
Given the desired degree, returns the number of data points required for interpolation.
Since linear interpolation can only generate a first degree polynomial, this function
always returns 2.
| 参数名称 | 类型 | 描述信息 |
|---|---|---|
degree |
number | The desired degree of interpolation. |
返回值:
This function always returns 2.
static Cesium.LinearApproximation.interpolateOrderZero(x, xTable, yTable, yStride, result) → Array.<number>
Interpolates values using linear approximation.
| 参数名称 | 类型 | 描述信息 |
|---|---|---|
x |
number | The independent variable for which the dependent variables will be interpolated. |
xTable |
Array.<number> | The array of independent variables to use to interpolate. The values in this array must be in increasing order and the same value must not occur twice in the array. |
yTable |
Array.<number> | The array of dependent variables to use to interpolate. For a set of three dependent values (p,q,w) at time 1 and time 2 this should be as follows: {p1, q1, w1, p2, q2, w2}. |
yStride |
number | The number of dependent variable values in yTable corresponding to each independent variable value in xTable. |
result |
Array.<number> | 可选 An existing array into which to store the result. |
返回值:
The array of interpolated values, or the result parameter if one was provided.
