Smooth Modifier#

The Smooth modifier smooths a mesh by flattening the angles between adjacent faces in it, just like the Smooth tool in Edit Mode. It smooths without subdividing the mesh, the number of vertices remains the same.

This modifier is not limited to smoothing, though. Its control factor can be configured outside the (0.0 to 1.0) range (including negative values), which can result in interesting deformations.

The Smooth modifier.#

Ось

Enable/disable the modifier in the X, Y and/or Z axes directions.

Фактор (factor)

Controls the smoothing amount. Higher values will increase the effect.

Values outside expected range (above 1.0 or below 0.0) will distort the mesh.

Повторить

The number of smoothing iterations, equivalent to executing the Smooth tool multiple times.

Группа вершин (vertex group)

If set, restrict the effect to the only vertices in that vertex group. This allows for selective, real-time smoothing, by painting vertex weights.

Переставить <->

Инвертирует влияние выбранной группы вершин, что означает, что теперь группа представляет вершины, которые не будут деформированы модификатором.

Эта настройка меняет значения веса группы на противоположные.

Algorithm#

The calculation done by the Smooth modifier is a simple and logical one, and can be thought of as the geometric equivalent of blurring images.

Each new vertex position is simply moved towards the average position of all its neighbor vertices (topologically speaking, i.e. the vertices directly connected to it by an edge).
