Quicktip: Abstract Shapes

comments 12
Free Tutorials

After publishing the VDB denting tutorial, we received some questions regarding how we created the geometry used in the preview rendering for that tutorial. In this quicktip we’ll show you how to create the organic shapes we used when testing that setup. It’s a neat combination of geometry and VDBs.

    would you mind telling which Hardware you use??
    Just RAM/CPU/GPU

    Apart from that… Thumbs up !! Clear loud audio, not too much talking around.

    • Heyhey,
      we’re using different hardware. For example my personal workstations are one quite old i7-990x with 12GB RAM and one GTX580, my newer is an i7-3920 with 32GB RAM and 2xGTX780 + 1xGTX980Ti. At the office we still have other configs. As far as Houdini is concerned you’re good if you have a fast CPU (at least a 6-core i7) and at least 32GB (better 64GB) of RAM.
      Cheers,

        Thanks for that, so I can have kind of a rough estimate how much coffee to prepare, when tryin to”recreate” Your Tutorials…

        I am actually a physics/CS student, but our 9TFlops cluster is sadly not available for Houdini…:-(

        So I have tostick with my laptop and expand it at its limits… (32GB+SSD)

        THX again for the Tuts&info

      • Hi Moritz,

        A bit off-topic, what kind of HDD size would you recommend for simulating/caching setups of a scale such as those in all your tutorials?

        Flawless platform – thanks for the tutorials!

        • Hard to say. I personally have a 256GB SSD as primary disk and a 2TB HDD as data drive. Nowadays I’d go for a 512 GB SSD though. In general bigger = better ๐Ÿ™‚

    Thank you very much for the tutorials! I am quite new to Houdini so it helps me a lot.

    In your tutorials you connect points and then turn these into wireframes. ( as well in your loops and subdivisions) tutorial I was wondering if there is a way to connect these to polygons? like somehow from connected points to a polygon mesh. been struggling for a while now with that issue.
    would be great if you could help

    thank you very much!

    • Hi Felicia,

      for me the most straightforward (and maybe not very clever way) to come up with something like what you’re mentioning is this setup:

      https://www.dropbox.com/s/8gpr8gcdnf8v4c7/connect_adjacent_with_polys_and_polylines.hip?dl=1

      Is that what you are looking for? In genereal you have to figure out which points should form a polygon and that you’d have to tell Houdini somehow. In the above setup I’m just generating the N nearest triangles. I’m sure there are lots of variations on this topic ๐Ÿ™‚

      • Also you might want to have a look at the Tetrahedralize-SOP.

        • Felicia Fuchs

          Thank you for your fast reply ๐Ÿ™‚

          Tetrahedralize-SOP what I was looking for in this case but the other solution gives me some very interesting effects now and I will certainly play around with it some more once Iยดve finished this project!

          Very cool.
          Cheers!
