Colors/Groups Exchanger (add-on)

Working in parametric design with a particular focus on blender’s parametric features, and the possibilities to exchanging information from/to other softwares I started to develop this new add-on.

During last workshop adaptABILITY in Bratilsava, Andrea Graziano and me introduced participants to some strategies for connecting blender to grasshopper through informations stored in vertex colors that can be exported as .ply file without need of scripting.

In blender there are quite interesting tools for working with vertex colors and vertex groups (vertex weight) but there is no an easy way for create a connection between these two layers of information stored inside the vertices of the mesh.

The add-on that I prepared is called Colors/Groups Exchanger and it allows to use two different commands: Vertex Colors to Vertex Groups and Vertex Group to Vertex Colors.

Vertex Colors to Vertex Groups

Sometimes can be useful to use informations of vertex colors in order to control some modifiers, physics or the behaviour of shape-keys.

vertex_colors_to_vertex_groups_command

 

Using this command it is possible to store one or more colors channels inside vertex groups (gray, red, blue, green, inverted).

colors_to_weight_options

For instance vertex colors are pretty useful for creating a grayscale map containing informations about mesh curvature. This tool is called Dirty Vertex Colors:

 colors_to_weight_dirty

Or maybe you prefer to use light shading for parametrically control some particular effect on the surface of your geometry:

 colors_to_weight_light

Or simply use some colors information incoming from external softwares for interact with your geometry.

 

Vertex Group to Vertex Colors

The second command that I’m going to explain is Vertex Group to Vertex Colors. It allows to move information from vertex-weight groups to colors, maybe because you want to export these informations to external softwares or simply because you want to render vertex groups.

vertex_group_to_vertex_colors_command

 weight_to_colors_options

One of the coolest way to work with vertex weight is to use some dedicated modifiers, like for instance Vertex Weight Proximity:

 weight_to_colors

We are waiting to do a new workshop about Blender and Grasshopper in order to going deeper in this interesting topic. Check Co-de-iT website for updates, or tell us if you would like that we organize one in your city.

 Cheers

spectrum { embodiments } – processing workshop in Rovinj (Croatia)

spectrum { embodiments }
Hotel LONE | Rovinj | Croatia | 27th – 31st August 2012

The more we explore the architecture of matter, the more what we get looks more and more like information; yet, infor-
mation needs a body in order to express itself as such. Architecture starts when the embodiment process takes place,
from the set of relations that define a system, by defining relations among independent objects (which, in turn, are
information systems on a finer scale). By coding the behavioral rules of interacting autonomous agents and topological
manifolds, emergent hierarchies and differentiated yet coherently related spatial and geometric conditions flourish form-
ing a spectrum (a condition that is not limited to a specific set of values but can vary infinitely within a continuum), with
a cascade of local symmetries, gradients and singularities emerging from pure information systems.
The workshop will speculate through codes written in Processing on autonomy of form and the relation among behavioral
rules and morphogenesis. Rather than trying to reductively solve dualities like autonomy/dependency, whole/parts, het-
erogeneity/homogeneity the workshop aims to exploit them as a fuel for dynamic, competitive or collaborative creation of
higher complexity and the source of a spectrum of possibilities in finding novel forms.seeable forms with no precedents.
We will write our own unconventional programming strategies in the scripting- framework Processing.
