How to control distribution of (mesh object)particles inside Volume


I set up a particle system to distribute cylinders inside Suzanne.
I want have high concentration in the center and less toward Sazannes faces.
How can I influence the distribution?

The only additional option you have for this is the Texture context. You can supply a gradient image and then use that value to cause size and density falloff inside the object, from the center out. It’s not perfect, though.
