Simulating Brain Waves

Hi L,

A 3d model file of a Brain neuron, decimated for use in Isadora with rights approval from https://eyewire.org - Not a waveform but a great asset associated with brain anatomy. Let me know if you are interested.

Best wishes

[ANSWERED] Connecting an Arduino Uno with Isadora

@m_theater It's now working! I've left the eom char value at 10, when I set it to 13 the actor didn't output a number.

I much appreciate your help!

Best, Simon

[ANSWERED] iPhone sensors as an input

@bonemap

Hi Russell, thank you very much. Both apps work fine, TouchOSC is easy to program, stable and reliable. GyrOSC works as well but the sensors are very sensitive even with the smoother at max.I was thinking of using it for motion captures the range of the Kinect and Orbbec sensors is very limited.

Will keep you posted, Hendrik

[ANSWERED] Track rotation

@dbini Thanks a lot for that idea. I would need to dynamically split the window to do that, since the dancer might turn in any place on stage. Maybe I could on one side find the blob center and use it to place the split and have several eyes++ running on different virtual stages. I'll have to check out some day. Unfortunately I'm not very constant in my dedidaction to dig into izzy.

[ANSWERED] Motion Trigger

I would like that have a motion sensor located at a point that way people walk by it, it triggers actors within Isadora.

The simplest way to do this: Video In Watcher -> Difference -> Calc Brightness

The Difference actor compares the current frame and the previous frame. Where ever they are different, you'll see grey/white areas.

By measuring the brightness of the frame using the Calc Brightness, you can discern if there is movement in the frame. The more movement there is, the higher the output of Calc Brightness.

The values coming out of Calc Brightness usually need to be scaled up because they can be quite small if you're looking at a large area and the amount of movement is not very great (e.g., a camera looking at people walking.) You can do this using a Limit Scale Value actor.

Finally you'll use a Comparator or Compare Guarded actor to trigger based on the output of Calc Brightness or the Limit Scale Value actor crossing some threshold.

See if that gets you going. ;-)

Best Wishes,
Mark
