Vector Fields and Polysurface Flowlines

UPDATE: I ended up simulating the strata patterning by creating hundreds of gradually differentiated surfaces and then using those to section my original polysurface, this seemed to be the most clean and effective way to create the effect. Final result below:

UPDATE: The definition now works in a similar manner to the single surface fluid definition posted a few weeks ago. The movement of each particle is primarily governed by whatever its previous movement was, allowing for a smoother flow across the polysurface, as I was having some issues at kinks between surfaces. The vector field becomes a secondary influence which allows for control over the flow lines in particular places where the uvs of the geometry are producing unwanted strata lines. Shoot me an email if you’re interested in seeing the definition.

For a studio project I have been working on simulating rock strata using various types of particle flow in grasshopper. The goal of the project is to create a definition that can be manipulated and controlled to an extent that a single network of flow lines can produce certain programmatic and circulation functions (stairs, canopies, seating, handrails) as well as creating a fluid and dynamic interior effect. The current definition takes input particles and iteratively maps them to the closest face of a poly surface, evaluating  UVs and selecting a dominant flow whilst using vector fields to articulate specific movement across the geometry.

  1. Hey! It looks great! How did you manage to get the particle flow in grasshopper?

  2. Hey! It looks great! How did you manage to get the particle flow? Is it possible for you to explain it? Thanks!

  3. this is cool! is the rock strata thing a result of the particle lines or are the particle lines based off the rock strata?
