Thread Subject: how to generalize the random numbers from the empirical tri-variate distribution

Hi,
Does somebody know how to generalize the random numbers from the empirical distribution? This distribution is 3D and is not some well-known one like Gaussian, etc.
e.g. p(x,y,z) is given, how to generalize the random data that satisfies this pdf?
This is a real research problem. Pls give me a hint,Thanks!

Sorry for the typo: it is "generate", not "generalize".
