# random number visualization without generator (Spectral Test)

Does anyone have codes for using only numbers to make this kind of random-number visualization and not requiring a number generator?

Could you explain what you mean by "using only numbers"? –  Sjoerd C. de Vries Jul 16 '13 at 5:55

The code used in the demonstration is like this.

Manipulate[
Graphics3D[
Point[pointCoordinates],
ViewPoint -> UserView,
ImageSize -> {450, 400}],
{
{NumPoints, 5000, "number of points"},
{100 -> "100", 500 -> "500", 1000 -> "1000", 2500 -> "2500",
5000 -> "5000"}
},
{
{UserView, {-2.1, -2.5, 4}, ""}, {{1.3, -2.4, 2} -> "View 1",
{-2, -2.5, 1} -> "View 2", {-1.85, -2.5, 1} -> "View 3",
{-2.1, -2.5, 4} -> "View 4", {-2, -3, 0} -> "View 5",
{-2, -2.5, 2} -> "View 6", {-2, -3.2, -0.5} -> "View 7",
{-2, -2.66, 2} -> "View 8"}, ControlType -> Setter
},

I take it you don't want to use the same code to generate the points. Whatever it is you want to do, replace pointCoordinates with your point generation code which depends on NumPoints.
