Points From Volume surface node

Creates set of regular points filling a volume.

See also: Scatter

This operator is used to generate a regular set of points that fill a given volume. This can be useful for generating a field of particles, or initializing a particle fluid.

Parameters

Initial Configuration

The configuration of the points to be generated, before any jitter is applied.

Grid

A loosely packed configuration that places the points at the vertices of a regular three-dimensional grid.

Tetrahedral

A tightly packed configuration placing points at equal distance from each of the three other closest points.

Point Separation

The smallest distance between any two of the generated points in the initial configuration.

Tip

Increasing this value will generated fewer total points, but will be faster to process.

Jitter Seed

Random seed for creating jitter.

Jitter Scale

The amount of jitter to apply to the positional values of the points. Jitter causes random changes to the positions of the points.

Tip

Set this value to 0 if no jitter whatsoever is desired.

Add Scale

Creates the pscale attribute and sets it to 2x the particle separation. This allows the Particle Fluid Surfacer SOP to get the right scale for rebuilding the original surface.
