I think the equations  would just be

u(xx) + u(yy) + u(zz) = 0 and

u(x+1,y,z) + u(x,y+1,z) + u(x-1,y,z) + u(x,y-1,z) + u(x,y,z+1) + u(x,y,z-1) =
6*u(x,y,z)

I could convert my code quite easy to 3D for testing purposes but it would
require lots of RAM to run. Then I would write a macro that outputs an object/volume
as voxel image slice by slice as animation. What's the format of the pov
voxel image type (for input to pov)?

This setup would be enough to determine how useful Volume Connector :) vould be.
