I would like to add the image texture to the mesh (wheat plant leaf). However,
the image could not attached on the mesh properly. It seems I need set
uv_vectors to control...I tried but not successful. Could you please show me how
to do that? Thanks.


    camera {
        perspective
        location <0.00,0.00,50.00>
        look_at <0.00,0.00,0.0>
        right <1,0,0>
        angle 10
        sky z
        rotate <20,0,0.00>
    }


light_source { <25, 25, 100> color rgb 1 }

#declare p_map6=pigment {image_map{png "wheat.png" interpolate 2}}

plane { <0,0,1>, 0 texture {pigment {color rgb <0.5,0.5,0>}} }

#declare leafmap=
texture{pigment {p_map6}}

#declare wheat =  union{
#declare GEOMID_329306648_155281880 = object {
