Cắt Nội Khung Xương Thẳng Đứng

This add-on makes 'inset polygons', which you get when you advance the edges of the polygon inwards at a constant rate. Sometimes when you do that, an advancing edge shrinks to nothing, or edges hit an advancing concave corner. The algorithm tries to do the right thing when this happens: one or more new polygons may form at that point, and insetting can continue inside those new polygons.

You can either inset a single polygon or you can treat groups of polygons connected together as a single region, forming a complicated polygon (that may include holes) to be insetted as a unit.

In addition to insetting, it is often useful to raise or lower the inset polygon (perpendicular to the inset plane), so a parameter to do that is included also.

Tỷ Lệ

Phần Trăm

Means that amounts are a percentage of the amount for a full inset.

Tuyệt Đối

Means that the amounts are in units.

Số Lượng/Số/Lượng

The distance to move the edges inward.

Chiều Cao

The distance to move the inset polygons upward.

Khu Vực

If checked, treat all selected faces as a region to be inset, otherwise inset each face individually.

Chi Tiết Kỹ Thuật

The method used is described on the Straight Skeleton Wikipedia page. Consider this starting polygonal region:

As the edges move inward at a constant speed, two kinds of events can happen. One is that an advancing corner can hit an advancing edge, as seen on the right part of this picture:

When this happens, the inset polygon splits into two.

The other is that an advancing edge can shrink to a point. When the whole process continues until the end, you get something like this:

One cool thing about this algorithm is that if you move upwards or downwards (perpendicular to the inset plane) at a constant speed, you form 'roofs' with a fixed pitch.
