PGR-Meandering-Paths ( is a Blender-Plugin (written in Python), which creates (randomly) 3D-meandering 'paths' within a defined area. It is written for Blender 2.4x. The script makes Blender curves of type "3D", to which another curve-object with adjustable size is assigned as bevel-object (you can choose between three basic shapes). This is also known as "sweep" or "extrusion-profile".

The script creates the 3D-curves along the x-axis of a beforehand as bounding-box selected mesh-object. You can choose between three types of startpoint-distribution on the Y-Z-plane of the bounding-box and also the number of steps along the x-axis.

At present, there are these different types of "meandering":

The end-points can be set to sit oppositely to the startpoints.

New since version V0.1.0 is the possibility to create a random animation of the curves. Several paramters can be adjusted to influence the animation. The created animation is based on Blenders 'shape-keys', so it is possible to readjust the animation afterwards.

Illustrations of the options

Startpunkt-Verteilung 1

Startpoint-distribution #1:
First in the center of the Y-Z-plane rest circularly around the center.

Startpunkt-Verteilung 2

Startpoint-distribution #2:
stacked; depending of aspect ratio and area of the Y-Z-plane the count of paths can differ.

Startpunkt-Verteilung 3

Startpoint-distribution #3:
random distribution; startpoints may even overlap.
