Point Jitter surface node

Jitters points in random directions.

See also: Mountain, Point

This node will randomize point locations by slightly altering their values. This is useful when precisely aligned data can be a problem. For example, a set of springs that are exactly aligned might be in precise balance that is unrealistic. Jittering the point positions will break the artificial symmetry.

This node works on points.

Group

Points to jitter.

Scale

Overall scale of the offset to move the points. Points are jittered by a value of -0.5 to 0.5 times this scale, and then modified by the other scales.

Axis Scales

Each axis of jitter is scaled by the corresponding scale here. This can be used to achieve a two dimensional jitter by setting the unwanted axis to 0.

Seed

The random number seed used to generate the jitter values. Changing this will create a different set of jitter offsets.

Use PScale

If enabled, the pscale point attribute will be used to further scale the jitter amount. This provides per-point jitter control.
