平滑修改器

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

Smooth Modifier applied to a subdivided cube.

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.

选项

Axis

开启或关闭修改器在X、Y、Z轴方向上的应用。

X、Y、Z轴

因子
The factor to control the smoothing amount. Higher values will increase the effect. Values outside this range (above 1.0 or below 0.0) distort the mesh.
重复
The number of smoothing iterations, equivalent to executing the Smooth tool multiple times.
顶点组
顶点组名,用来限制仅对一组顶点起效。通过绘制顶点权重达到选择性的、实时的平滑或增强效果。

算法

平滑修改器所做的计算逻辑很简单,可以想象成对图像模糊的几何体版本。

每个新的顶点位置只是相邻顶点(通过边相连的顶点)位置的平均值。
