For this Animation Node experiment I created Metaballs changing their size depending on their position in a noisefield

For this AnimationNode experiment I made growing vines out of vertices using random 2d noise patterns. I used a grid mesh to generate the inital vertices and iterate over the list of vertices in the mesh using a loop. Then I used a second loop to generate the spline for each vertex.

The number of vertices in each spline is controlled by the framerate and each vertex is moved by a random amount along the x- and y-axis.

The node setup is a bit too complicated for a screenshot but you can download the blend file here

I saw a hudini video tutorial a few weeks ago that shows how to use a noise field to create particle trails that look like electronic schematics. I really liked the effect and recreated it using a small processing script. To create the effect I set up some particles, that use a noisefield to influence their velocity. Before the velocity is added to the particles potion the vector is normalized and then each component is converted to an integer value - this limits the values to the x and y component to -1,0 and 1. The resulting vector is then scaled to the original length of the vector and added to the position of the particles.

I just noticed that the last time I posted a processing sketch was in july - which is a shame. So to all the processing fans among my readers who are eagerly waiting for another sketch - here is my newest processing sketch.

I created a particle fountain in the middle of the screen and added a little bit of noise to the velocity of each particle. The noise fields are influenced by the current velocity and to add a bit of movement to the noisefield I also add a factor based on the current framecount to the noise function. If a particle leaves the screen it gets deactivated and is then reactivated in the middle of the screen at a random time.

In this processing sketch I'm using the perlin noise function to create a curl noise vector field

I modified my noise modulo sketch from last week by adding a second noisefield perpendicular to the first one. I got this idea from a facebook comment - which unfortunately has been deleted, so I can't credit the author. The two noisefield functions use different offsets and move the field with different speeds to create a more asymetric image
