Following the course of this afternoon, I will just upload some codes to make interactive 3d plots, in R.

> library(rgl)
> library(evd);
> data(lossalae)
> U=rank(lossalae[,1]+rnorm(nrow(lossalae),
+ mean=0,sd=.001))/(nrow(lossalae)+1)
> V=rank(lossalae[,2])/(nrow(lossalae)+1)
> M=kde2d(qnorm(U),qnorm(V),n=35)
> library(rgl)
> persp3d(M$x,M$y,M$z,col='green',
+ xlab="loss",ylab="alae",zlab="")
