Thank you for your reply. But the following is what I did.
In *.pov file
     .......
     mesh {
   smooth_triangle { <-18.2369, 57.4258, 115.298>,
<-0.333333, -0.666667, -0.666667>, <-32.0698, 57.4258, 99.813>,
<0.449391, -0.887923, 0.098189>, <-32.0698, 57.4258, 115.298>,
<0.816497, -0.408248, -0.408248> }
              }
And the Mesh->Data->Vertices I saw is<-18.2369, -32.0698, -32.0698>. Is this
the (x,y,z) of a single Vertex?Thank you.
