Proportional Editing is a way of transforming selected elements while also affecting the nearby unselected elements. The farther away an unselected element is, the less it will be affected (hence the "proportional"). This feature is very useful for smoothly deforming dense meshes.

Note

Blender also has a 雕刻 workflow that contains brushes and tools for proportionally editing a mesh without seeing the individual vertices.

控制器

Disable O

衰减编辑关闭,仅所选顶点会受到影响。

Enable O

定义的半径范围内所选顶点以外的顶点受到影响。

影响

可以分别使用鼠标滚轮 WheelUpWheelDownPageUpPageDown 增加或减小衰减编辑工具影响的半径。当改变半径时,围绕选中项的点将相应地调整它们的位置。

衰减

While editing, you can change the curve profile by either clicking the Falloff icon in the header or pressing Shift-O to get a pie menu.

物体模式

Proportional Editing is typically used in Edit Mode, but it can also be used in Object Mode. The tool then works on entire objects rather than individual mesh components.

In the image below, the leftmost cylinder is being scaled up vertically, which also affects the cylinders near it.

编辑模式

When working with dense geometry, it can become difficult to make subtle adjustments without causing visible lumps and creases in the model's surface. When you face situations like this, Proportional Editing can help.

选项

仅连接 Alt-O

衰减编辑不光是依据半径,还需要通过相连的几何体传递。 这意味着可以按衰减编辑一只手手指的顶点,而不会影响其他手指。虽然其他顶点在物理上接近(在3D空间中),但它们远离网格的拓扑边连接。当 仅连接 激活时,该图标中心将为蓝色。 此模式仅适用于 编辑模式

从视图投影

在应用半径时忽略沿视图的深度。

例子

The image below shows the final render of a low-poly landscape obtained by moving up the vertices of a triangulated grid with Proportional Editing enabled.
