Look up G4TessellatedSolid. You might be able to use the tabulated values of D(x,y) as vertices. Add whatever vertices are needed to make it a solid. Of course for this to make sense D(x,y) must be well behaved (but if it's physical then it will be). You must also evaluate whether the tessellation approximates the surface adequately.

Recent Geant4 releases have improved tracking for this so that many thousands of faces can be handled efficiently.
