Build a ring of spheres with a Python script

Steps

1. Click New Project.

2. Press Ctrl+Shift+E. The Python Script Editor opens in a window of its own.

   

3. Click in the code, select all of it with Ctrl+A (Cmd+A on a Mac) and paste this script over it:

   python

   import math
   import kinematic.graph
   
   g = kinematic.graph.current()
   count = 12
   ring = g.create_node("3DGeoMerge", position=(800, 600), config={"num_inputs": count})
   
   for i in range(count):
       angle = i / count * math.tau
       ball = g.create_node("3DGeoSphere", position=(i % 2 * 320, i // 2 * 260), config={
           "radius": 0.2,
           "t_tx": math.cos(angle) * 1.5,
           "t_tz": math.sin(angle) * 1.5,
           "t_ty": math.sin(angle * 3) * 0.4,
       })
       g.connect(ball, "Geometry_Out", ring, f"Geometry_In_{i + 1}")
   
   print(f"Made {count} spheres and joined them in {ring.id}")

4. Choose Run > Run Script, or press F5. The script adds a Merge node with twelve inputs, then twelve spheres. Each sphere gets a radius and a place on the circle (t_tx, t_tz and t_ty are its Move X, Move Z and Move Y), and each one is wired into the Merge.

5. In the main window's Objects panel, click Merge 1. The viewport shows the whole ring, rising and falling three times as it goes around.

   

6. Color it. Open Surface > Material > New PBR material. In the Objects panel, under Materials, click the new material, then in Properties click the hex box beside Base color, type #3FA7A0 and press Enter.

7. Hover over the viewport and press Shift+H to hide the handles. Save with File > Save.
