Method Detail

getLength

int getLength(int i)

Returns the number of grid points in a given dimension.

Parameters:

i - The index of the dimension.

Returns:

The number of grid points in dimension i.

getLengths

int[] getLengths()

Returns the number of grid points in all dimensions.

Returns:

The number of grid points in all dimensions. Element [i] is the number of grid points in dimension i.

gridToValue

float[][] gridToValue(float[][] grid)
               throws VisADException

Returns the interpolated samples of the set corresponding to an array of grid points with non-integer coordinates.

Parameters:

grid - The coordinates of the interpolation grid points for which interpolated sample values are desired. grid[i][j] is the i-th grid coordinate of the j-th interpolation point.

Returns:

The interpolated samples of the set. Element [i][j] is the i-th coordinate of the j-th interpolation point.

Throws:

VisADException - VisAD failure.

valueToGrid

float[][] valueToGrid(float[][] value)
               throws VisADException

Returns the non-integer grid coordinates corresponding to an array of points.

Parameters:

value - The array of points for which non-integer grid coordinates are desired. value[i][j] is the i-th coordinate of the j-th point.

Returns:

The array of grid coordinates corresponding to the points. Element [i][j] is the i-th non-integer grid coordinate of the j-th point.

Throws:

VisADException - VisAD failure.
