How to spin (or rotate) a shape

You’ve almost got it! Like that, but with Navigator between Ramps and arches. The patch above would give you double mirroring on the input to Navigator.

You can also use Staircase to do mirror function, but may have to tweak it a little to dial it in.

3 of the 4 functions in Arch are patched out utility block versions of some of the Shapechanger circuitry!

I tried by using Staircase for the second H mirror and was able to spin things!!! Still need to tweak some more but will share some notes over the weekend. I may need to head out and grab a second Arch.

I’m using doorway to try and scale but looks like I’m missing the ability to skew the ramps from what I’ve learned from watching videos of how Shapechnager behaves.

What I’m looking to do at its simplest is have a white diamond shape spinning 360” set against a black background.

Would this be possible without the scale and skew functions of Shapechanger?

what is the analog function of the mirror? just wondering what it does to the signals… if its just rectifiers or something else?

It is an absolute rectifier (very fast, with video opamps and high speed schottky diodes) but in a frequency doubling configuration. So the input signal as 0-1V is scaled to +/-1V so that it will slice right in the center. The rectifier then slices positive/negative portions and inverts the negative portion to give 0-1V on output, but at double frequency.

Yes you can get a white diamond rotating that way! You will want to run H/V ramps into Navigator, then essentially you are doing a sawtooth to triangle (frequency doubler) conversion on the outputs. You can use Arch to do that or Staircase (at low frequency settings, you want 2X). Basically you are converting the sawtooth ramps into triangle ramps AFTER the rotation. Then you mix them (a crossfader works well for this, and gives you something similar to the skew control) and then you key them (using Doorway or Cortex) to get the flat shape results.

Hello,
so if navigator doesn t spin a shape, wath exactly does it do ?.
thx

Navigator does spin the shape but from my understanding the mirrroring needs to take place after which is why I’m using Arch as a replacement for Shapechanger.

Navigator rotates the XY dimensions of the “scene” that the shape is created within.

Even more :slight_smile:

I’ve been waiting a long time to get this technique down so please bear with me sharing lots of experiments.

Patch notes to follow.

Patch notes.

This is the patch for the videos above but if you were to remove Navigator you would still achieve the same look. Also im using one Staircase and one Arch. A cheaper route would be to use 2 x Arch. If you were to use 2 x Staircase that would up open up a world of variation but would be a bit more expensive.

The videos basically show the same patch but with different levels of mirroring switched on. Spinning shapes 1 shows the patch with all mirroring switched off. The only mirroring is whats taking place via arch and staircase to draw the shape. The rest of the videos show different combinations of the mirroring options on VC ramps and Navigator switched on.

More variations. Similar kind of as patch as before.

Did you end up picking up a double of either Staircase or Arch? Arch is such a Swiss army knife in the majority of our patches that I can see the potential to gain significant utility from such a relatively low foot print module.

I didn’t get round the grabbing a second Arch but its on my wish list. I had filled my current case and only just started setting up a second case for new stuff so now can start planning to expand.

Would Arch bring a lot to a setup that already has Shapechanger in terms of bending and shaping things?

We are in the same boat. The Orion series grossly complicates our understanding of how best to augment it’s real ultimate power.

Yes for sure. Arch is my favourite module by far. Can get a world of shape variations of out when using ramps. Also processing control signals can get some amazing results.

Cool! I’m having a bit trouble understanding logic stuff in video synthesis. I just got the multi gate and love it but I guess arch is doing something entirely different to the signal.
