•how and when a concept becomes black-boxed? by which processes?
@Sven: what matters is the input/output, stimulus/response [--> “black-box of the beyond” (#zolmat writing)] --> transfer characteristics, data-flow, the ontology of the “internal working” : “open” exchanges inforamtion about its interactions }--> open-source is part of the tradition of anthropocene system thinking: network synthesis, system engineering, theory of the organism, evolutionary theory, thermodynamics, and world system perspective

what are the nodes of energy in interdigitalities intra-actions in human-machine relations?

***we are belonging to a set of cultures that regularly believes in the idiom of: organism =/= technology
--> this little ontological dichotomous device is doing serious worldings, making and destroying worlds

technologies of descriptive practices
technology is descriptive practice
technology: anything describable as a technology --> idiom اصطلاح

(#workshop in Stuttgart 11.04.2017 with Femke http://pad.constantvzw.org/p/possiblebodies.rigging)
provisional sketch for a workshop on “Rigging,” notes and nodes


on the notion and practice of Rig in CG
(CG as in “computational gesture”)

[title]
on Rigging and skinning: stories for cultivating creation and creatures of the industrial empire.
a practice in: rhetoric of technical reasoning in inorganic skeletal animacies.


•I begin with the position that believes in the essential ambiguity of technology
•let's look at some terms and notions and the ways they are enacted, practiced, and embodied, and to practice some hermeneutic fluency in phenomenological conditions in what we call character animation


KEYWORDS: soft bodies, skin, skinnig, Rig, Rigging, unwrapping, fold, CG, animation, locomotion, kinectics, skeleton, mechanics, interface, technology,

Rigs are about:
-ways of arranging space, time and matter : like a sentence, that sticks words sequentially together in a certain way. Rig would be a way those elements are attached to one another in time and space.
[*] --> one-dimenisional skeletal Rigs are generally intereseting for my research, because of the specific sequential order that many forms of culture take. (for example, “tradition” is from that famility of Rigs, a string of things in a particular order and not another. [---> go to totem columns]. “language” is another one.)
◦what are the degrees of flexibilty, stretch and tention between the nodes in a Rig?
◦what a substitution in a string-Rig might change the ways that being is animated, and therefore change the meaning?
-that means: change the Rig, and you will change the ways space and time are arranged
-that means: thinking about Rigs is like thinking about the language, or better: ontological commitments embedded in language. and since we are interested in materiality [that means: material human-technology relations], i would ask: what are the material objects that this language commits us to? to be more exact: what are the material objects that the language-Rig commits the CG-hacker to?
-ontological assumptions embeded in any “device” (English grammar, CG Rigs, architect's tools, a definition in language, etc.)
-Rigs are clever technological provisional constructions, (always) setup for a specific naturalization.
-Rigs articulate animacies, that is to say: they are almost linguistic structures that shape or determine our animations
-Rigs do consequential work
-how elements are arranged together, how they are composed, how they are brought into relation in the space of a field, narrative, text, environment, etc

whenever you give a definition (a metaphor, a concept) and work with it, and find yourself committed to certain findings, tracings and meanings because of that: you are working with a Rig. that is to say: Rigs are definitional structures, not arguments themselves, but their conditions.
then the question would be: when do you know that it is time to dismantle a Rig? how to recognize, learn to reuse or repurpose old Rigs?

in CG the business of Rigging and Rig-making is handed to the engineering talent and point of view, it has made a pure technical problem.



skeletal, it's all about the ‘arm’

an arm is a spaciotemporal particularity
the organisms that crafted in their bodies the subphylum vertebrata, a terrestrial technology for moving the flesh.
the images we make are made in the image of the one-with-arms

mechanical
bipedal
facial
quadrupedal
many arms and legs

(strictly) possible tranformational arrangements

how a being is Rigged into transformational particularities
in this sense, the question of the Rig is ontoloical, specially in a world populated by devices and techniques, interfaces and folds upon folds, constructions that do things for another constructions, Rigs that translate

kinematic equations, inverse kinematics, the math of it is called the Jacobian inverse technique

“In robotics, inverse kinematics makes use of the kinematics equations to determine the joint parameters that provide a desired position for each of the robot's end-effectors. Specification of the movement of a robot so that its end-effectors achieve the desired tasks is known as motion planning.”

{\frac  {\partial p_{i}}{\partial x_{k}}}\approx {\frac  {p_{i}(x_{{0,k}}+h)-p_{i}(x_{0})}{h}}

how do we animate quadrupeds, invertebrates, phyla, rotifera (wheel-animals), and so on; for each a mathematics must be invented in order and terms of digital computationality.

“anatomy” is always “imaginary anatomy” (in CG, comtemporary dance, medicine, love, etc.)



a skin has to deal with:
“Global Stiffness Structural Optimization”



Rig talks to mesh, telling it how to move, how to be.
how we evolved from jelly to skelletal? something tense, intensified in space, some flesh attached to it. how the concrete mineral came back to assert itself in the terms of bones of the organism?
(a mesh is a matrix of points in which the neighboring points only matter to eachother. mesh is the result of the study of topology in mathematical notions of space and structure, with demands of an industry interested in the representation of surface. mesh is interested by creatures that have a skin, and have stakes in tactility?)
Rig is that constructed logic or grammar that allows mesh deformation in one way and not another. made of enfolded layers of code and constraint


story of the bone
the flow of matter and energy, flow of intensification between sortal processes, organisms, and minerals.


this is about how matter is defined, in everyday CG work


how certain kinetic skeletal rigs naturalize the relationships between volume and surface and skeleton --> which is always symbolic

notes by other participants of the workshop:
http://pad.constantvzw.org/p/possiblebodies.sina.workshop

some post-workshop notes:

questions of:
•causality: how Rig-thinking can help to have a better understanding of causal relationships between the ‘moved’ and ‘mover’?
•control: how can we have a more interesting ontology of constraints that allows more interesting articulations of control---(that one-way flow of influence between the soft and the rigid)?
•process and becoming: how the technological nature of the Rig and its relations with the image of the organism in CG can be Rigged for a different articulation of the lived-body? and to which extend the Rig can be helpfull to think about the becoming of the beings-of-the-CG [...]
