When constructing look-up tables, there is an option to look at a color graph. When working with n-dimension look-up tables, its gets harder to visualize the output values. My suggestion is to implement a 3D-mesh similar to what Matlab Simulink offers for their look-up tables.
One additional request is to also offer the us to choice of interpolation method between linear and cubic. This could be useful in same cases.
