Hmmm,
Two ways:
1) Interesting way but probably not what you want is to set the color of the
vertex to include an alpha component and fade across your vertices, using
modulate with the texture. I know this works in opengl, I assume it does in
Java3d.
2) The next way is to use a transparent polygon, and blend a texture in
which has an ever increasing (decreasing?) alpha, this is the technique I
use to make a terrain transition, I overlay two meshes and fade one out.
