Visualization of a list of 3D points coordinates with a perspective

Dear MathGroup members, I have a list containing 3D coordinates of a number of points, like this one lst={{3.30414, -2.86064, -2.54648}, {4.06572, 3.80403, 1.68897}, {-1.72822, -2.03097, -4.1024}, ...} I would like to visualize them by plotting them. To plot them as a set of points may be trivially done by say, ListPointPlot3D. Alternatively, it may be visualized as a set of spheres with unit radius and centered in the points specified by the list, e.g. in the point {3.30414, -2.86064, -2.54648}, in {4.06572, 3.80403, 1.68897} etc. Now comes the question. I would like to do it in such a way that the size (and may be the color) of each point or sphere would depend upon one of the coordinates (say, y). In other words, the size and the of the first point specified by lst with y=-2.86064 would be smaller than that of the second point that has y=3.80403. The color or darkness may also depend upon y. This would give a feeling of a perspective. Do you have an idea of how to do this? Best, Alexei -- Alexei Boulbitch, Dr., habil. Senior Scientist IEE S.A.
