SeedColors is six RGB values in 6-by-3 matrix form.

Default colors are [1 0 0;0 1 0;0 0 1;0 1 1;1 0 1;1 1 0]::[R;G;B;C;M;Y]

Each color corresponds to +x, +y, +z, -x, -y, -z directions.

Surface transparency: Alpha is either a scalar or array of two elements.

Alpha(1) = FaceAlpha

Alpha(end)= EdgeAlpha

*If the size of U,V,W is m-by-n, then the size of X,Y,Z can be either

m-by-n or m+1-by-n+1.

For the latter case, the vector (u,v,w) at (i,j)-site is considered to be

on the surface element of [x(i:i+1,j:j+1),y(i:i+1,j:j+1),z(i:i+1,j:j+1)]
