DualGraph –
Cinema4D plugin

Do you want to change a classic Delaunay triangle-mesh to a cell like Voronoi topology, with little effort? Β Then the Cinema4D python plugin “DualGraph” is for you. It computes the dual graph of the Delaunay tesselation. That means it finds the midpoints of the original triangles and connects these to form new ngons. Resulting in a beautiful mesh.

DualMesh Demo

Here you can see the plugin in action. Input is left – output is right. Make sure to use triangles as an input. Quadrangles work, but the resulting mesh looks pretty much like the original due to the nature of the algorithm. Ngons as an input are currently not supported. The plugin runs on Mac and PC as it is written in Python.

  1. Hi Manuel & Moritz,

    This thing you are doing here is absolutely amazing πŸ™‚
    I’ve been struggling&learning Houdini myself for the last year, and this is just a wonderful resource.

    Anyway congrats on this awesome project, i already went over everything and i can’t wait to see more.

    Cheers,
    Yam.

    Thank you very mach for your great work, but i don’t see any options for plugin, just one type of cells :(( On your images much more, why ?!! But thanks one more time πŸ˜‰

      The plugin generates the cells based on the input polygons. So the structure of the triangles determines the size of the cells and their shape. In my images I used manual and semi-automatic selections techniques in C4D to merge cells and extrude them.

      • hi…i love the renderings…what do you mean by “semi automatic selections” … you lost me there πŸ™‚

    Thanks so much for these marvelous tutorials and exciting new techniques!

  4. Hi, and thank you-I downloaded the plugin, but in my object manager, all I see is the icon, and in the attributes window, nothing , no field for input or output,please tell me what I am doing wrong? is it possible to provide a sample file?, thank you, CZ

    • Manuel says

      This is due to the fact that the plugin works in the c4d native way. Please put the input object into the plugin object as a child. And make sure you’re running R17.

    Please is there a manual on how to use this plugin?

    • Moritz says

      Hi Toheeb, actually it’s pretty straightforward – just drag a triangulated mesh underneath the plugin in the object manager and you’re done.

      Cheers,
      Moritz

    hey guys, fantastic plugin and website! Any ideas if this plugin would work on Team render or other servers?

    • Manuel says

      I did not test it. But I assume it will. If you test it, please tell me about your findings.

    How do you install it, I cant find it in the plugins tab after I put it in the C4D plugins folder. I’m on r17
