Further rgl()/spheres3d() query

to work for a couple of the positions, with no text added in most cases.
Could anyone offer any suggestions?

overlaying points and lines on a surface3d rgl plot with axes
Hi R users and experts,
I am interested in learning more about the use of 3D plots. Specifically, I
want to add points and lines to a surface plot. And get the axes and labels
plotted also. Here is what I have tried with an example data set :
library(rgl)
vol2 <- 2*volcano # Exaggerate the relief
library(reshape)
mvol2 <- melt(vol2)
str(mvol2)
# First, persp and persp3d plots do not succeed

Fwd: (KAME-snap 9012) racoon in the kame project
FYI, looks like support for Racoon is ending. Does anyone have any
experience with the version in ipsec-tools ?
