多边形建形#

参考

The Poly Build tool uses many built operators in an interactive way to add, delete, or move geometry. This is extremely useful for retopology.

工具设置#

创建四边形: Automatically split edges in triangles to maintain the quad topology.

Add Geometry Ctrl-LMB: Vertices or faces can be created by moving the cursor close to an element and using the hotkey to add a vertex or face. The tool first tries to create a face, however, if not enough geometry exists to create a face it will try to extrude a vertex to the cursor. When creating a face, the face can be previewed by holding Ctrl.
Delete Mesh Elements Shift-LMB: Vertices, edges, and faces will be deleted by hovering over the element and using the hotkey. Elements with two or more connected elements will be Dissolved. The element you are trying to delete will be highlighted in red while holding Ctrl.
移动顶点 鼠标左键: Vertices can be moved by hovering over the vertex and using to hotkey to grab and move the vertex to the desired location. The vertex you are trying to move will be highlighted in blue while hovering over it.
挤出边线 鼠标左键: Edges can be extruded by moving the cursor close to an edge and using the hotkey to extrude the edge to the desired location. The edge you are trying to extrude will be highlighted in blue while hovering over it.

Tip

It is useful to enable vertex snapping and use 按距离合并 while tweaking vertices to combine them.
