What you want is slightly different from what contourf3d does. Most
likely, you have a 3D matrix and what you want is to plot representative 2D
slices of that matrix with x, y, and z all being spatial coordinates. What
contourf3d does is plots 2D data with x and y being spatial and z being the
"intensity" value, not the spatial value.
I have an idea of how to do what you want, but I need to test it a bit
first. I will get back to you on that.
