SCI-Arc _ Malleable Assemblies / Group B - Hololens Video

Hi Gwyll,

Our group has recorded several videos, with use the hololens device portal, of our first experiances with the headset. As we keep developing our model, and also our fabrication process with the hololens, we will keep posting more videos to share our experience.

SCI-Arc Malleable Assmblies, Group B

Hey @mateodeza

Thanks for posting a few videos. These are from your first experiment a couple of weeks ago right? I seem to recall we already had a brief discussion about these ones, specifically:

  1. If you’re constructing fairly long and detailed parts like these, you’ll need a solid work surface that you can attach both your placement QR code and the part you are fabricating to so that you can ensure that the hologram and the physical part are aligned.
  2. If you’re simplifying the parts to just a couple of bends, then you might be able to get away with Dwayne’s idea of hand bending the parts over a jig (e.g. a piece of PVC pipe) and then using a hologram to check the precision of each part. In this case you would want to set up the hologram so it is ‘ready to hand’ e.g. right next to the place where you are bending the part. You would probably also want a holographic interface for easily stepping through parts so you aren’t always returning to the laptop.
  3. You can lock rhino layers so you don’t accidentally move the holographic parts around during fabrication.
  4. You probably only want to show a single part at a time.
  5. At this scale, drift and precision aren’t really going to be an issue for you. But you will want to make sure you’re using a placement QR code just so you have repeatability in placing your model in the same spot, and also to ensure that your holograms are placed as close to his code as possible to minimize any possible drift.

Have you used the HoloLens for fabrication since this experiment a few weeks ago? I’m pretty keen to see videos of the setup you are intending to work with for your final piece.

Hi Gwyll,

Many thanks for your previous comments. These were very useful for us to continue using the hololens and fologram software.

We want to share new developed videos with you, where we use the hololens for the seminar fabrication process.

Here are the following links:

Many thanks,

Hey @mateodeza

Thanks for sharing the videos. How are you finding working with the hololens so far? What is the most difficult part of the process? How precise are the parts? Are you planning to digitize the formed parts at all to measure this?

The use of the green material for the holograms as well as rendering smoother curves seems to be working pretty well. Generally speaking you will find it easier to work with the hololens if you follow the advice mentioned earlier (General notes from Week 8 and feedback to other groups e.g. Group D_Hololens Video), specifically:

  • Orient the holograms of the parts you are forming so that any flat segments of the part are sitting directly on top of a flat work surface. This will allow you to more accurately form them as well as pin them to the work surface so that you can form the 3D parts of the curves without the entire part moving around as you’re struggling with now.
  • If the above works well, you might consider rationalizing your parts so that some segment of them is always 2D so you can pin them down during forming.
  • Try to work on a workbench rather than the floor to make it easier to view holograms in 3D space rather than primarily top - down
  • Disable the hand meshes from the Fologram settings menu so they aren’t too distracting
  • You can use the Sync Text component in grasshopper to sync text tags that always orient to the camera rather than using 3D text in Rhino.
