Tonight I had an idea.<\/p>\n\n\n\n

RADIAL AND AZIMUTHAL VISCOSITY<\/p>\n\n\n\n

Maybe I can split my usual viscosity<\/strong> based on the attractor position into two terms: viscR<\/em>, and viscO<\/em> (think theta \u03b8), where R and O are of a local polar coordinate system centered on the attractor<\/strong>. This way, a bunch of particles tied to this attractor – with spring force, gravity… whatever – might not dodge the attractor when moving but rush more into it, straight. Maybe I can play with those and all…<\/p>\n\n\n\n

Let’s go!

Ok so things did not go as planned.

I went on CodePen, forked my previous pen Spipa Circle<\/a> and reduced the grid to only 3 points on which attractors can teleport.<\/p>\n\n\n

Spipa Circle<\/p>\n\n\n\n

I was planning on experimenting the splitting of the usual viscosity into viscR<\/em> and viscO<\/em> with flocks of particles moving around the triangle of attractors. Instead I started to see a very nice motion of particles within the triangle, which reminded me of a few experiments with vanishing points<\/strong>. So I just went on polishing the pen in this direction!<\/p>\n\n\n\n
