I have following surface plot of a multivariate time series

library(zoo); library(rgl); library(xts)
mat <- matrix(nrow=250, ncol=10)
for (i in 1:250) mat[i,] <- rnorm(1, 100, 10) + seq(10:19)
Z <- zooreg(mat, start=as.Date("2000-01-01"))

time.axis <- axTicksByTime(Z); col=c("yellow","red")
yred <- colorRampPalette(col); col1 =
Z1 <- coredata(Z)

persp3d(z=Z1,x=(1:NROW(Z1)), y=(1:NCOL(Z1)),aspect=c(1, 1, 0.5), col = col1)

Now I want to show the dates along the x-axis. Can anyone please help me how
to do that? I am specially interested to do it in RGL device.
