Put the data into a matrix d, with columns of x, y and z coordinates, and call points3d(d).

If you know more about the structure of your data you can probably do better. For example, you might be able to join pairs of points (using segments3d(d)) or triples of points (using triangles3d(d).) Both of those will look terrible if the data is not structured so that they make sense.

If you want to see a scale on the plot, finish by calling decorate3d() to add axes and scales.
