Metaball 3d_02

Metaball 02

A parametric field created in Grasshopper from a curves with variable fillet generated from a metaball 2d system.


Curves from metaball 2d speculation.

(Cvs)Field 01

First exercize on parametric field generated from a curves. Original GH definition by E.Scripelliti.

RH control Points01

A rhinoscript that extracts control points form a curve and connects cps with a dashed polyline.

Densification points on curve01

Quickly exercise about if,then else logic in Grasshopper. This definition creates points on curve with different densification depending on angle values from tangent on point and y vector at the same point.
