For the midterm, I decided to do an biosystems with creatures. As first step, I did a flocking simulation for the creatures’ movement part. As I assume my creatures live submarine, I use dark blue color for the whole scene.
Apart from flocking, I also add attraction and repulsion forces of mouse. Thus I can interact with those “particles” to make it more interesting.
And I also add an tail for the particles, just to see its trace. I use an little trick of Fbo for the tail. I draw two Fbo on each other, like the feeadback loop in two mirrors. And use transparency of Fbo to make it fade out. The effect was interesting.
(The screen recording makes it a bit stuck, it runs smoothly without screen recording.)
