Subdividing adds resolution to the mesh by dividing faces or edges into smaller units.
This process follows a few rules depending on the situation:
When only one edge of a triangle or quad is selected, that face is turned into a quad or N-gon respectively. If the Create N-Gons option is disabled, the face is split into triangles instead.
面の2つの辺が選択されている場合:
If the face is a triangle, a new edge is created between the two new vertices, subdividing the triangle into a triangle and a quad.
If the face is a quad and the edges are neighbors, the face is split according to the Quad Corner Type setting (see below).
If the face is a quad and the edges are opposite, the quad is just subdivided in two quads by the edge linking the two new vertices.
面の3つの辺が選択されている場合:
If the face is a triangle, this means the whole face is selected and it is subdivided into four smaller triangles.
面が四角形の場合、最初に2つの反対側の辺が上記のように細分割されます。次に、 "中間" 辺が細分割され、上記のように1つの辺のみの新しい"サブ四角形" に影響を与えます。
When all four edges of a quad are selected, the face is subdivided into four smaller quads.
When one or more edges of an N-gon are selected, the individual edges will be subdivided but the face will stay unsubdivided.
Options(オプション)¶
These options are available in the Adjust Last Operation panel after running the operator:
- Number of Cuts(分割数)
The number of cuts per edge to make. By default this is 1, cutting edges in half. A value of 2 will cut them into thirds, and so on.
- Smoothness(スムーズ)
Displaces subdivisions to maintain approximate curvature. The effect is similar to the way the Subdivision Surface(サブディビジョンサーフェス)モディファイアー might deform the mesh.
- Create N-Gons
When unchecked, forces the subdivision to create triangles or quads instead of n-gons (see examples below).
- Quad Corner Type
Controls the subdivision for quads with two selected, neighboring edges.
- Inner Vertices(内部頂点)
The selected edges are subdivided, then an edge is created between the two new vertices, creating a small triangle. This edge is also subdivided, and the "inner vertex" thus created is linked by another edge to the one opposite to the original selected edges. This results in a triangle and two quads.
- Path(パス)
The selected edges are subdivided, then new edges are created between the new vertices as well as the existing outer vertices. This results in two triangles and a quad.
- Straight Cut(ストレートカット)
The selected edges are subdivided, then an edge is created between the two new vertices, creating a small triangle and N-gon. If Create N-Gons is unchecked, this option works like Inner Vertices instead.
- Fan(ファン)
The quad is subdivided into a fan of a quad and two triangles, the common vertex being the one opposite to the selected edges.
- Fractal(フラクタル)
メッシュが細分割された後、頂点をランダムな方向に移動します。
- Along Normal(法線に追従)
頂点をランダムな方向ではなく、法線に沿って移動させます。
Along Normal set to 1.¶
- Random Seed(ランダムシード)
Fractal(フラクタル) で使うノイズ関数のランダムシードを変更します。シード値ごとに異なる結果を生成します。
同じメッシュで異なるシード値。¶
