I’ve seen very beautiful examples of similar compositions made by using vector field components in Grasshopper. Just tried to make my own animate field lines to see how they float over force dynamics. In essence, these compositions could also be done using regular vector components but the field components make life much more easier by merging different forces together rather quickly. Here is my Grasshopper definition (be careful it may slow the computer down) [GHX: 0.9.0014] As you see below, it is a quite small definition that creates beautiful complexity. Although we […]

After playing with vector fields in 2d (here) it was quite easy to create a 3d surface deformation. Here is my first experiment on a regular triangular grid’s three-dimensional behaviour within a vector space, that includes a point charge of varying z coordinates. That makes field lines escape to a bounding box, instead of a bounding rectangle. Again, you may play with force decay, number of samples, and the “grid blast” parameter, which is just a t value evaluation of force fields. The first animation below shows the travelling point […]

Back to serious business, I finally managed to make use of force fields in Grasshopper. It was a couple of updates ago, a new tool group emerged in vector tab, introducing different  types of vector fields to users. These fields could be merged together to form more complex effects. However, I created a very simple example of how we can use those components to create a distortion on a system (such as a regular tessellation).   Using attractor forces (usually in geometric forms) is one of the fundamental concepts of […]
