I have different sets of data points in 3d space (x,y,z). I have a set of points (x and y coordinates) for every value of coordinate z. For example, for z=13 I have n-points (n>50) with coordinates (x;y) that describe a certain region, for z=14 I have m-points (m>50) with coordinates (x;y) that describe a certain region. For z=15 I have only 4 points (yellow dots in the attached image), I want to generate, starting from those 4 points, a bigger set of points for z=15 (for example a set of 50 points) that follows the behavior of the z=14 set of points. Any suggestions or ideas I can start from?

That is pretty simple right....To whatever z = 14 points are there i.e. (x,y) simple replace z values with z = 15. And out of these points select 50 equidistant points.
