Hi, i have a set of point cloud data(xyz-coordinate). i want to sample it by the density. How can i do this ?

If you sample uniformly you'll get more sample locations where your data is denser and less sample locations where it is less dense. Is that what you want? On the other hand, if you sample it more where it's denser then you'll get inordinately more data points from the dense region than you should. Is that really what you want (I wouldn't think so)?
