Dear all,
I always appreciate your help. I am an electrical engineer. I am using a tool for timing analysis of a circuit. I would like to interpolate results from two timing reports at different voltages (0.945V and 0.78V). If voltage is decreased, data arrival time is increased.

DESCRIPTION
Each of these functions casts a ray (or rays) through a three-dimensional(3D) data set, then computes and returns the interpolated samples
at each step along the way.
In trilinear interpolation, the value at point P is computed from its eight surrounding neighbors based on the equation below.
P = (1-a)*(1-b)*(1-c)*P0 +
a*(1-b)*(1-c)*Px + (1-a)*b*(1-c)*Py + (1-a)*(1-b)*c*Pz +
a*b*(1-c)*Pxy + a*(1-b)*c*Pxz + (1-a)*b*c*Pyz +
a*b*c*Pxyz
where a, b, and c are the fractional parts of the coordinates of point P.
The trilinear interpolation is represented by the following figure:
Printed copy or docs.sun.com displays a figure that represents the trilinear interpolation.
In nearest neighbor operation, the sample value at point P is replaced by the value of the nearest neighbor voxel.
PARAMETERS
Each of the functions takes the following arguments:
rays Casting rays.
blk Volume data in the blocked format.
buffer Working buffer.
RETURN VALUES
Each of the functions returns MLIB_SUCCESS if successful. Otherwise it returns MLIB_FAILURE.
