I need to draw a cylinder/tube joining two points. I am trying to make something presentable, I have been able to do it using lines3d. But is it possible to 
increase the thickness of the lines? The size parameter does not work. Does any one have any suggestions?

Thanks ../Murli

pts<-structure(list(x = c(-0.975688, -0.975688), y = c(9.258795, -9.258795
), z = c(-1.8, 1.8)), .Names = c("x", "y", "z"), class = "data.frame", row.names = c(NA,

plot3d(pts$x,pts$y,pts$z, col="grey", size=2, box=FALSE, axes=FALSE, type="s")
lines3d(pts$x,pts$y,pts$z, col="grey", size=2)
