This is a HACK and should not be here. Bilinear interpolation of 2D or 3D-vector organised as float[][][].

Parameters:

v - the 2-D matrix or 3-D volume to be interpolated.

x - the integer x position at which to interpolate.

y - the integer x position at which to interpolate.

dx - the x-weight to use for interpolation.

dy - the y-weight to use for interpolation.

Returns:

a vector with the interpolated x and y values.
