Boids is an algorithm for simulating the flocking behaviour of birds.

This show tries to do something similar. Not by simulation, but with a fixed path.

The arrow is a 3D model attached to a sketch layer. All 8 arrows use the same path, only with a different position (POSITION prop) and offset (WRITER prop). This creates the suggestion that they all follow the leader.

Clearly this system can't be used to simulate hundreds of arrows/birds for a long period of time, but the advantage is that you have full control which is great for intros when you only have a few seconds to make them fly elegantly around a text.

The ProceduralTextures\RGB effect is used to make them more colourful.

The 3D path has been created in Bixelangelo:

Thank you amiga for the idea!

Yes, sketch is a possibility

There's nothing, that BT can't do.

I'm amazed at your ability to gen up something so quickly that is so beautiful!

Glad you like the idea, but I was inspired mostly by the old conversation between you, Komies and Alex-Raymond T. from the link below.

But again, thanks for all of the BT fun you make possible!

Great Michiel, can i distribute this animation?

Franco Aversa, 3 years ago

Thank you Franco!

You may use the media files to create a video and do with the video file whatever you want. Commercial use included.

But do not spread the media files like the BT, EPS and X files. This is a very important distinction. More info here:

Thanks Michiel, I asked for it on purpose. It is important to respect the rules.
But people registered with the community can download it from here, right?

Franco Aversa, 3 years ago

Thank you Michiel for this sharing explained in detail, and to Amiga for the implementation. And very proud to be unconsciously at the origin of this remarkable work.
For information, I took my video on this flight of starlings as an intro for my "Travel book" based on the "Picture-> Page Flipper2" model, for which, I found some construction tips that I will try to share shortly ...

Franco, the answer is yes. This is true for all uploads by all artists, including yourself. So no need to ask this again for every post.

Alex-Raymond T, thank you!

michiel, 3 years ago

Thank you all!

The download has been updated with an improved 3D model.
