4D data plot

I had originally a set of X, Y, Z data representing atoms that land on a surfaces within a cubic vacuum chamber. Also the wall of the chamber act as possible landing position. I converted this data set using IGOR into a density plot, i.e., a three dimensional grid of points equally spaced with a value N assigned to each point. The assigned value is the number of atoms landing within the grid cell. I have used the scatter plot option from GIZMO to represent the grid point, and colored them using a ColorWave. I noticed that some other software can generate a density plot based on scattered data, i.e., N=f(X,Y,Z) and show this as a smooth surface. Does this option exists in IGOR?

Thanks,
