My first instanced geometry

Building on the momentum of making my way through my very, very first noise displacement tutorial, I had a go at Polyhop’s instancing geometry in TouchDesigner tutorial.

Again, you literally start with a ‘blank canvas’ and then slowly build up a network that results in a fun and visually interesting output.

My key takeaways

  • It’s possible to assemble 3D forms from various geometry with a merge SOP.
  • You can use Python expressions to access parameters e.g., scale and height of spheres at the end of the tube – super cool and efficient!
  • Split the screen to create a clear and uncluttered workspace e.g., TOP viewer, and then Display modal window, and uncheck background CHOPs.
  • Because Nulls act like a conduit, they’re great for creating space and increasing flexibility in a network – easier to swap out or experiment with inputs in a given network.
  • Polyhop’s expression “moving a SOP to CHOP land” – love it!

My first noise displacement

Super-stoked about taking my very first steps with the visual coding software TouchDesigner by making my way through Polyhop’s Noise Displacement Tutorial – it’s a fun tutorial with just the right amount of detail designed especially for first timers like me.

You literally start with a ‘blank canvas’ and then over time slowly build up to something something visually interesting and fun to play with – I’m most likely going to adopt this workflow while I’m still finding my feet with TouchDesigner.

My key takeaways

  • Learning how to chain together Noise TOPs
  • Using Nulls to connect nodes
  • Polyhop’s expression “toot the parameters” – love it!

RPM Challenge 2016

This is The Challenge – Record an album in 28 days, just because you can. That’s 10 songs or 35 minutes of original material recorded during the month of February. Go ahead…put it to tape.

I was up for it. So I created a profile on the RPM Challenge page, recorded, processed the audio and then posted it to bandcamp. Awesome.

The Shaker box

This was the first Shaker Box that I built. I repurposed a slightly worn contact mic I had prepared earlier. My reuse of the old contact mic may explain a few things about the shaker box’s performance. These photos first appeared on my Greetings from…Flickr stream.

Concept drawing for the shaker box.

Starting off, I needed a box of some description to house the contact mic and rattly bits. I didn't have a small metal enclosure or tin handy so I used a plastic jiffy box that I had. Happy with the plastic substitute I drilled a hole in it with a 9mm drill bit to ensure a snug fit for the audio jack.

Next step was to prep the piezo that was already assembled as a contact mic. Gently warm the heat shrink tube with a lighter to ensure that the soldered connections are protected.

Now solder the wires connected to the piezo to the audio jack. One to the tip and the other to the sleeve.

I just temporarily duct taped the piezo onto the lid of the jiffy box. The tape won't protect the piezo that much once we start shaking...

Here is a detail shot.

Mounted the jack and tossed in some hair clips and bits of plastic, some people would want to use metal for a potential more "harsh noise" sound. Regardless of the material the piezo will still pick up the "rattle".

The lid is on, the jack has been mounted and it's all duct taped up!

Plug in your lead and hold tight to your little box and...

Shake your thing!
