If you are using rgl::plot3d, plot the second with add=TRUE.

As David said, use colours or something to distinguish.

For example,

library(rgl)

data1 <- matrix(rnorm(30), ncol=3)
plot3d(data1, col="red", type="s")

data2 <- matrix(rnorm(30)+2, ncol=3)
plot3d(data2, col="blue", type="s", add=TRUE)
