Using the default DataRendererJ3D and changing the ColoringAttributes?

Hi,

I am trying to visualize an Irregular3DSet with a
color map. I am using DisplayImplJ3D with the default
DataRendererJ3D. The interpolation of the colors
between the vertices is not smooth. 

Since the 3D displays are built on top of Java3D I was
hoping there was some way for me to get and set the
javax.media.j3d.ColoringAttributes to NICEST, FASTEST,
SHADE_GOURAUD, SHADE_FLAT etc. "without" creating a
new DataRenderer. Is this possible? If so how?


Thank you in advance. 

Regards,

Surekha
