You'll need to do the trimming yourself. There isn't currently any support for user-controlled clipping regions in rgl. That is: for the usual case where x and y are vectors, to limit x or y to a certain range, just take a subset of those values, and a subset of the rows or columns of z. To limit the range of z, set out of range entries to NA. It will probably look ugly because it will get a very ragged edge. It appears that the NA handling for the case where x or y is a matrix leaves something to be desired.
