Is there a way to generate a random point cloud by volume?

[magneto]

I use the Scatter SOP but it only generates on the surface of a model. Is there a way to generate it by using the whole volume of the object or without using an object at all?

Thanks

Use IsoOffsetSOP to convert an object into volume first, then append ScatterSOP.

- Use an IsoOffset on the geometry.

- Now use the Scatter SOP.

As an alternative you can use the "Points from Volume" SOP.

EDIT: Dang, Symek is fast

Thanks guys. I didn't use volumes as much before so now it makes sense.

Btw will add points to your posts tomorrow after RC (recharge)

Never mind. Those two above beat me.

EDIT:

Actually, there is another way. You can use POP context and just birth particles with a help of "Source POP" and Emission type set to Volume. You don't have to use ISOoffset with this method. Instead of seed parameter, to randomize point placement, you can than use various parameters on POP network node itself , like "Preroll Time","Start Time". Just make sure to set particle "life expectancy" to something shorter than it is by default so you don't have to set those parameters to high to start notice change. One sec. should be good.
