Software : Rhino 3d and Grasshopper (Explicit History)
Level : Intermediate

Description : In this Rhino / Grasshopper video tutorial we expand on a previous video from the site, Rhino - Patterning Based on Point Distance with Grasshopper. The idea is to use 2 points rather than one.  The logic is borrowed from Andy Payne on a 3ds Max model with wire parameters. Basically the idea is to drive the radius of the circles with the distance between the point(s). The circles then use the MIN component and a “range” factor to limit how big the circles can get as well as the area of influence of each point.  I’m not proposing this is the most elegant solution but it got the job done ;).  Please feel free to post alternative solutions in the forum.  Here is the thread for this post with the source files.

Topics Covered
-Distance Component
-MIN Component
-Using 2 attractors
-Making Grids

Software : Rhino 3d and Grasshopper (Explicit History)
Level : Beginner
Description : In this Rhino / Grasshopper video tutorial we rebuild the shift tutorial provided by David Rutten on the Grasshopper blog. I hope to do one of these per file David has posted up.  As simple as the interface is to understand when one comes at the software for the first time this can be a bit overwhelming.  I just want to help make the dissection process as simple as possible . Please have a look in the forum for more Grasshopper files and images.

Topics Covered
-Divide curve by Number
-XForms
-Using the Shift component

These are 2 of the 8 definitions posted by TAZ on the forum.   Here is an excerpt from what was posted:

“By way of example I tried to replicate with a NURBS surface the mathematically derived mesh generation script from the RhinoScript101 primer.  If you really want to have fun you can check the mesh from the script against the NURBS surface from the definition.  Obviously The NURBS geometry doesn’t handle sharp edges, creases, or singularities very well but if the resolution setting is high enough the approximation is pretty close.”

So……. Explicit History has been re-branded as Grasshopper. I am also glad to say that David Rutten did not just change the name. He has also TONS of new functionality. This programs was amazing before now it’s even better. Further more this is only release 0.3 i would imagine they have plenty more on deck for future releases.
