public class GridLoader
extends Object
implements IColorMappable
```
The GridLoader utility offers a way to convert coordinates mode. When input data is made of lists of x, y, and z points, and that these lists actually contain data that regularly lie on a squared grid (orthonormal grid), the GridLoader allows a smart retrieving of data by providing:
- an 1D array of sorted X coordinates (without doublon).
- an 1D array of sorted Y coordinates (without doublon).
- an 2D array of Z coordinates syncronized with arrays X and Y.
If some data are missing for representing this grid, missing data will be considered as NaN. The actual management of missing values is thus left to the object that loads these data.
In the following example, the o represent a NaN Z value, meaning that there was no (x[i],y[i],z[i]) triplet for representing it correctly:
11111111 y 11111111 11o11111 11111111 x
If some points are missing in the input list to generate a complete grid, the output grid will contain Z=NaN values for missing coordinates.

    Set the array of data. X,Y, and Z are arrays that must implicitely represent an orthonormal grid. If some data are missing for representing this grid, missing data will be considered as NaN. The actual management of missing values is thus left to the object that loads these data. In the following example, the o represent a NaN Z value, meaning that there was no (x[i],y[i],z[i]) triplet for representing it correctly:
    11111111 y 11111111 11o11111 11111111 x While parsing input data, the minimal and maximal Z values are computed, in order to have the loader ready for computing polygons color with a colormap.
    Parameters: x - list of x coordinates y - list of y coordinates z - list of z coordinates Throws: an - IllegalArgumentException if x, y , and z have not the same size
  getSquarePolygons public Vector<Polygon> getSquarePolygons(IColorMap cmap, Color colorFactor) Deprecated. getExtrapolatedRingPolygons public List<Polygon> getExtrapolatedRingPolygons(float ringMax, IColorMap cmap, Color colorFactor) Deprecated. extrapolate public void extrapolate(int n) Deprecated. Add extrapolated points on the grid. If the grid is too small for extrapolation, the arrays are maximized getInterpolatedRingPolygons public List<Polygon> getInterpolatedRingPolygons(float ringMin, float ringMax, IColorMap cmap, Color colorFactor) Deprecated. Load data standing on an orthonormal grid. Each input point (i.e. the association of x[i], y[j], z[i][j]) will be represented by a polygon centered on this point. The default coordinates of this polygon will be: x[i-1], y[j+1], z[i-1][j+1] x[i-1], y[j-1], z[i-1][j-1] x[i+1], y[j-1], z[i+1][j-1] x[i+1], y[j+1], z[i+1][j+1] There are thus three types of polygons: those that stand completely inside the ringMin and ringMax radius and that have the previous coordinates. those that stand completely outside the ringMin and ringMax radius and that won't be added to the list of polygons. those that have some points in and some points out of the ringMin and ringMax radius. These polygons are recomputed so that "out" points are replaced by two points that make the smooth contour. According to the number of "out" points, the modified polygon will gather 3, 4, or 5 points. As a consequence, it is suggested to provide data ranging outside of ringMin and ringMax, in order to be sure to have a perfect round surface. Parameters: ringMin - the minimum radius of this ring. ringMax - the maximum radius of this ring. colorFactor - a weighting factor for the color returned by the Colormap. getMin public double getMin() Deprecated. Description copied from interface: IColorMappable Retrieve the lower value boundary for a IColorMap.
