Image Field02 ///////////////////////////////////////////////////////////

Testing image sampler component with a diagrid pattern tesselation. This is the source image :

Image Field01 ///////////////////////////////////////////////////////////

This definition works with new image sampler component. To work correctly make sure you're choosing Value(brightness) in filter option in the image sampler component and X e Y domain of the image sampler ( Setting option) longer than the texture image( easy way is to create a texture image big than the projection of the surface on the x,y plane).
The radius of the circle that have center at U,V points surface is connected with the brightness value of the texture image at the u,v points.

Attractor lines 02///////////////////////////////////////////////////////////

Multiple line attractor definition via Grasshopper. Evalauate Closest Points and Curve Closest Points is the key for this kind of attractor.

Magnetic field 01///////////////////////////////////////////////////////////

From a definition of Daniel Piker and inspired to the work of A-Engine i created this Grasshopper definition.

Phyllotaxis System 04///////////////////////////////////////////////////////////

From last post on Phyllotaxis System i've worked on a simple VB code in order to create the main profile to copy and rotate for a phyllotaxis, following one of the very useful tutorials on DesignReform.

Uneven Surface Diagrid 01///////////////////////////////////////////////////////////

A series of parametric exercises done in the past months. This is about controlling diagrid spacing with a Graph mapper component (from Grasshopper Primer_second edition manual).
