non-Blender: Data Driven Interactive Quadrangulation


More and more SIGGRAPH videos are starting to come in! Here's a nice one on an algorithm that allows for user-guided tessellation of meshes. Maybe a nice new feature for RetopoFlow, Jonathan? ;-)

About Author

Bart Veldhuizen

I have a LONG history with Blender - I wrote some of the earliest Blender tutorials, worked for Not a Number and helped run the crowdfunding campaign that open sourced Blender (the first one on the internet!). I founded BlenderNation in 2006 and have been editing it every single day since then ;-) I also run the Blender Artists forum and I'm Head of Community at Sketchfab.


  1. Beautiful, I might cry.

    I do question the default structure of the mesh, how can it be in 7 seven segments initially and still have visual topography.

    • If you watch the video, on the example of the old man, when the side of the face that he is working on changes, the other side changes to match. Now, this could just be mirroring at work, but it is all one mesh, so any changes to one side of the mesh must affect the other to match endpoints at least.

      I don't think the mesh is actually segmented. I think the mesh is split into logical groups, and then their is some overlap. I could be wrong, however.

      I so want this. Smart approach to be able to use the best topologies from the best artists by anybody.

  2. That is pretty awesome!

    The 3D preview that was used here reminds me a lot of Blender. I wonder if it's possible that they used Blender to avoid building a preview viewport from scratch.

  3. I have used this software and it is amazing. Blender is not the software they used for their viewport. But would be amazing to see this feature in blender.

    • That's not all that supprising. Did you get to use it at SIGGRAPH? Or is there a build online that we can use?

      • tyrant monkey on

        I don't what Detty is on about but are builds (you get one zipped folder with MacOS, Windows and Linux builds in it) available on their website and you are allowed to use it freely for non-commercial work. I've been playing around with it for the past week I haven't done anything remotely complex with it so I can't really speak of the in's and out of the system.

        Check the thread out on blenderartist in general discusions.

  4. Brian Lockett on

    Considering how many of these promising SIGGRAPH ideas we see bypassed for core Blender development, we'll see this implemented into Blender in, say, 5 years, if we're lucky? lol

    We still haven't even heard word of the quad-dominant remeshing proposal we saw a while back. This stuff is nice to dream about, but practically, it never becomes a priority in Blender development.

    • … seems like I was too tired … I wanted paraphrased note in description - "Maybe a nice new feature for RetopoFlow, Jonathan? ;-)", but direct it to hair system, there it would be also great feature to have -this recreation from images. Sorry for misunderstanding.
