I combined all my tga images into a .df3 file format
then i m doing this

#declare DENSFUNC=function
{
    pattern
    {
        density_file df3 "imoil.df3"
        interpolate 3
    }
}
isosurface {function { .2 - DENSFUNC(x,y,z) } }

but just a blank screen is rendered.
is my coding incorrect or do I need to alter the cam/light/threshold values ?
