#### Particle Group

The particle group to calculate the properties for.

#### Particles

The particle type of the Particle Group to use.
Passive
Vorticity
Liquid
Diffuse

#### Kernel

Follows

#### Density

This calculates the particle density of the given particle group (this is NOT a density of matter but only how close particles are located to each other in space).

#### Iso-Density

This calculates an unnormalized particle isodensity.

#### Weighted Position

This calculates a weighted position which is required for the anistropic mesher.

#### Influence Radius

To find particles nearby this radius defines the maximum distance around each particle to find neighboring particles.
If you are using it for a thin sheet algorithm, this radius should be equal to the radius used in the thin sheet algorithm.

#### Falloff

Defines the falloff kernel. See 'Kernel' for more detailed information.
