Vector Field Integration

Here's a component that finds the integral lines of 2d or 3d vector fields...

The way it works is very simple: you give it a list of sample points and associated vectors (1 vector for each sample point) and a start point, and it flows that start point along the vector field up to a specified iteration limit and step size. The advantage to having a generalized component like this is that along with things like principal curvature lines, it can also compute paths guided by isovists and visibility algorithms, principal stresses, etc. As long as the vector field is properly defined, it will do something...

looks interesting. Can you upload a demo 3dm and ghx?

Try this one...might take a minute to load. You'll also need the Isovist component in the latest release.

Great work Daniel!

Where can I find the IsoVist component?

Thanks,

Hi Giulio,

IsoVist was released as a standard GH component in v0.8.0008 its on the Intersection Tab.

Any news yet on Training Dates for Rhino Level II courses in July at the BCN office? Could you give Rodrigo a gentle nudge for me?

Rhino 4 sr9, GH 080009

Trying the Principal Curvature component, I get this error:You sure you set Copy Local to False on the OpenNurbs reference?

Interesting...does the Vector Field Integrator work?

Yes, works as described (very nice by the way!).

How about for future development you introduce a Vector component for the object in the field. Such as a vessel under power, you could also vary it along the length at different steps to simulate altering course.
