Density plot 3d for clustering

Good morning everybody.
I want to ask you if it is possibile to build a 3d density plot in order to show the density of a cluster, having the scores for the first 2 Principal Component for each individual.
I showed the density of each cluster using the package "ggplot2", but I've done it only in 2-dimension.
Is there any package or a specifical code for it?

Thank you very much,
