The quatrefoil is a common motif in medieval architecture. It is used as the plan for columns and compound piers in the Romanesque period (9th-12th centuries) and as wall openings and tracery in the Gothic period (12th-15th centuries).

A bracket is a support that cantilevers from a wall surface in order to support a structural member that does not extend to the ground.

The RoundedRectangle is useful Shape that can be used in plan or in section. It is controlled by width and height handles, as is a Rectangle Shape, but it also has a rounded corner radius handle. A similar result can be achieved by setting the roundness of a Rectangle, but with the segs parameter of the RoundedRectangle, you have more control of the segmentation of the corner curves.

The Rectangle

BastionMerger is a 3D Library item that let’s you get started with a maze-like level quickly. Once you select the BastionMerger, you will see its Plan Shape with point Handles at each control point. Clicking and dragging this handles allows you to easily manipulate the parapet walkways and the bastion walls in realtime with Shape merging magic taking care of intersections and openings in the bastion walls.

Clicking and dragging the point Handles of the BastionMerger.

Moving the purple point Handles moves the control vertices of the Plan Shape, while clicking and and dragging a blue point Handle adds a new vertex to the Plan Shape.

How it Works

Using the PlanRepeater2D node, it places rectangles representing the bastions at each vertex of a Plan shape.
