The result is an ellipse that has a two times larger radius in the x-direction than in the z-direction. Image with the green particles showing the original circle and the flame particles showing the ellipse:

The same is possible with 3D shapes like spheres, which we can scale in all 3 dimensions at once:
```
set {_sphere::*} to sphere with radius 1 and density 5
set {_scaled::*} to {_sphere::*} scaled by 2 in direction of vector 1, 2, 3
```
With locations:
```
set {_sphere::*} to sphere at player with radius 1 and density 5
set {_scaled::*} to {_sphere::*} scaled at player by 2 in direction of vector 1, 2, 3
```
Which results in an ellipsoid:

Note also that the ellipsoid has not more points than the sphere. Sometimes it is therefore more useful to make a bigger shape and then shrink it to keep a high density of points. We can change the previous example to use a big sphere and then shrink it:
```
set {_sphere::*} to sphere with radius 6 and density 5
set {_scaled::*} to {_sphere::*} scaled by 1 in direction of vector 1/3, 1/2, 1
```
Which results in an ellipsoid with a lot more points:
