How to disable the title bar of a window (undecorated window)

effect - the grey rectangle is the openframeworks window:

Openframeworks undecorated window.png

This tip depends on the renderer you are using! As i'm running linux (on a crappy computer, not sure it is valid for any linux-hardware rig), i had to modify the method setup in [OF_ROOT]/lib/openFrameworks/app/ofAppGLFWWindow.cpp.

ofAppGLFWWindow::setup(const ofGLFWWindowSettings & _settings) {
	
	...
	glfwDefaultWindowHints();
	//glfwWindowHint(GLFW_DECORATED, settings.decorated); // comment this line
	glfwWindowHint(GLFW_DECORATED, GL_FALSE); // force DECORATED to false

Then you have to recompile OF. Once again, i'm running linux so i just to do:

$ [OF_ROOT]/scripts/linux/./compileOF.sh

To view the result, just clean and recompile any app using OF: done!

All methods to manipulate the window are listed in [OF_ROOT]/lib/openFrameworks/app/ofAppRunner.cpp.

bool ofDoesHWOrientation();
ofPoint ofGetWindowSize();
ofRectangle ofGetWindowRect()
ofAppBaseWindow * ofGetWindowPtr();
void ofSetWindowPosition(int x, int y);
void ofSetWindowShape(int width, int height);
void ofSetWindowTitle(string title);
void ofEnableSetupScreen();
void ofDisableSetupScreen();
void ofSetFullscreen(bool fullscreen);
void ofToggleFullscreen();

You can also get the native objects, depending on the OS:

Display* ofGetX11Display();
Window  ofGetX11Window();

Tested on linux mint 18.3 & of v0.9.8

The city as a research

New Babylon

Constant new babylon model bw.jpg Constant new babylon model color.jpg.jpg

New Babylon is an anti-capitalist city, perceived and designed in 1959-74 as a future potentiality by visual artist Constant Nieuwenhuys

The city as an actor

Different story and/or artwork where the city is leaving its role of background to become an actual protagonist of the story, imposing its scale, structure and time to the human-like characters.

Dark city

Dark-city-screenshot.jpg

Darkcity, 100min, 1998, by Alex Proyas

The city is shifting every night, while population is in a catatonic sleep. The whole map and architecture is mixed up in front of our eyes, modifying the perception of structural stability, or at least very slow evolution, commonly inferred by the streets and buildings. This movie is the main inspiration for the city generator library.

Blame!

Blame.jpg Blame-killy and shibo.jpg

Blame! (original title: ブラム!), 1998 – 2003, by Tsutomu Nihei

The main character, killy, a taciturn and undetermined young adult, is wandering in an endless succession of super-structure (megastructures in the manga) enclosing cities and vast empty space. Along the 10 volumes covering an undefined time, from several years to hundreds. During this journey, the different action scenes are separated by long periods of absolute loneliness. In this story, the city is not decaying but self-regenerate thanks to giant building robots, apparently left on their own and continuously creating new structures. The city is not actually moving by itself, but has no other reason of expending else than the fact of build. It is a self-sufficient object, liberated from its utility to mankind.

Why I try to ban the word project from my vocabulary, why it is hard to remove it and proposal to replace it by work unit.

[fr] Le mot projet implique une projection dans le futur. Un projet désigne une chose potentielle qui sera réalisée plus tard, hypothétiquement. Il permet de se dégager de la responsabilité de sa réussite et plus important encore de son échec en repoussant sa concrétisation dans un avenir non-défini.

Le projet rejoint la vision occidentale du temps et de l'espace: un ensemble de points inter-connectés par des lignes. Le projet vise un point en évacuant la notion de déplacement, l'importance du temps passé en chemin. Son omni-présence dans le discours public le rend aussi hautement idéologique.

En abandonnant le mot projet, c'est une idéologie de l'entrepeunariat public et privé (dans le sens développement personnel) qui est remise en question, ainsi qu'une vision linéaire du temps et de l'espace. Dès qu'il est retiré du vocabulaire, un gros problème apparait rapidement lorsqu'il s'agit de produire un discours sur le travail d'un artiste. Ce trouble prend racine dans le manque de précision du mot.

Sans essayer de comprendre ce qu'il recouvre, il est difficile de s'en passer. Le mot projet désigne en effet simultanément et de manière indistincte:

  • l'intuition initiale qui a lancé le travail réflexif et pratique présent au cœur de son travail;
  • les différentes problématiques sociologiques, politiques, esthétiques et idéologiques qui sont présentent au sein de l'intuition, qui l'ont nourries ou grâce auxquelles elle a pu s'affiner;
  • les actes concrets accomplis dans le réel qui donnent une forme tangible aux deux points précédents.

Ceci sans vouloir hiérarchiser les 3 points ou imposer un ordre de pré-séance. Il s'agit plutôt de pôles interdépendants interagissant constamment entre eux. [...Idea:Work Unit...]

Carnages 2 [extra small] - sound by Gauthier Keyaerts

Presentation

[en] This work unit is based on the algorithmic processing of videos gleaned on pornographic platforms. The intention that guided the development of this algorithm aims to blur the obviousness and roughness of the sources and to turn them into an animated painting, twisting the mind of the watchers by eluding the direct representation of bodies without losing their presence, in a pictorial surface constantly morphing. It is also a way to trigger an awareness about the depiction of sexual act in the contemporary web-based world.

Etymology of the word of pornography.

1842, "ancient obscene painting, especially in temples of Bacchus," from French pornographie, from Greek pornographos "(one) depicting prostitutes," from porne "prostitute," originally "bought, purchased" (with an original notion, probably of "female slave sold for prostitution"), related to pernanai "to sell" (from PIE *perə-, variant of root *per- (5) "to traffic in, to sell") + graphein "to write" (see -graphy).

{{quote|Du 10 mai au 11 juin 2011, la galerie Charlot, qui a décidément toute ma confiance, héberge des oeuvres de François Zajega alias Frankie Zafe, artiste numérique dont la démarche m’a particulièrement plu. Je vous conseille d’aller y faire un tour, et surtout d’aller voir de nuit l’oeuvre interactive sur la vitrine de la galerie au 47 rue Charlot.

Avant d’aborder le sujet des oeuvres de François Zajega, il faut que je vous remette dans le contexte dans lequel je les ai vues. La veille, j’étais à la conférence de Matt Pyke & friends, un collectif d’artistes numériques, à la Gaîté lyrique. J’ai déjà écrit là-dessus, et depuis je me suis posé des questions sur ce qu’est l’art numérique et comment il se décline, en développant quelques idées. On peut commencer en dressant une histoire à très gros grains de l’art, sous forme de : arts premiers, art classique, art moderne et art contemporain, et de considérer l’art numérique comme démarrant à un temps zéro sur un nouveau terrain, dans une nouvelle histoire. Les époques de l’art « d’avant » ne sont alors plus successives mais simultanées, des courants parallèles. Avec cette approche, on pourrait alors qualifier un art numérique qui cherche à représenter avec ses propres moyens le réel qui l’entoure, ce monde qui lui est extérieur, étranger, comme un art numérique premier ou classique, en fonction des finalités qu’il poursuit. Pour aller plus loin, j’appellerai même art numérique analogique un art numérique dont la création procède par analogie à des objets du monde réel. C’est en ces termes, art numérique premier et/ou classique, art numérique analogique, qu’en première approximation je qualifierai l’oeuvre de Matt Pyke & friends.

theory

{{quote|One overly simple but useful definition is that generative art is art programmed using a computer that intentionally introduces randomness as part of its creation process. This often brings up two common but misguided viewpoints that hold people back from appreciating the beauty and nuance of generative art.

Myth One: The artist has complete control and the code is always executed exactly as written. Therefore, generative art lacks the elements of chance, accident, discovery, and spontaneity that often makes art great, if not at least human and approachable. [...Bookmarks...]

Modular structure research, 3d printable, light-weighted and that doesn't requires any tools to mount. One of the topic was also to use the electric wires as tensioner.

Versioning

Tri-lampadaire-screenshot002.png

version 001: jaws to snap the cable and clamps to constraint the jaws. The clamps were too weak to hold the pressure, and the jaws were bitting so much into the cable that the wire was seriously damage during installation.

Tri-lampadaire-screenshot004.png

version 002: Complete revision of the design. The arms are now made of wood and not plastic (print time and cost reduction), making the structure much more modular. The wire is locked without pressure in a locking maze embedded into a small part at the end of each arm. The pieces are drilled to re-enforce their structure.

Tri-lampadaire-screenshot003.png

version 003: The drilling was not making any significant difference on strength. It was also weakening the outer shell of the piece. So we dropped it. h. It was also weakening the outer shell of the piece. So we dropped it.

Tri-lampadaire-screenshot001.png

version 004: After building three modules, the design of the locking maze showed its limits: really hard to adjust the tension on wire and nearly impossible to unmount once the wire was pull tight into it. Therefore, we open the maze to make the wire adjustments easier. Result is convincing: the wire can now be mounted and unmounted easily, and the structure is stiffer.

Notes about computation of inverse kinematics, first implementation done in threejs.

Solving-ik-001.png

At this moment, the research is focusing on solving a 2 bones system, the leg in this case, but it would be applicable on the arms or any other part of a skeleton having at least 2 parents.

The main issue seems to be the computation of the knee position. All distances are easily computed:

  • upperleg (red) keeps its length
  • leg (yellow) keeps its length also
  • distance between the target and the origin of the upper leg can be easily computed in world space.

Rendering the position of the knee is crucial to compute the rotation of the upper leg. Once correct, the rotation of the leg will be simple to render, as it is the rotation from the current direction to the [knee - target] direction.

Spheres

A little warning: the graphic here above is in 2d. In a 3d world, the position of the knee is a circle on a sphere: any point being at the right distance of the target point and the upperleg origin will be a valid candidate! The circle of possibilities is the intersection of 2 spheres having their radii equals to bones length.

Solving-ik-002.png

The radius of the cyan circle can be solved by using this equation:

a = 1/(2d)sqrt(4d^2R^2-(d^2-r^2+R^2)^2) 

A little screenshot for better readability:

Sphere-Sphere Intersection.png

The tricky point is to forget about the spheres' position and only consider the distance of their centers as the d parameter. The normal of the intersection plane can be computed independently.


Implementation of the equation in an openprocessing sketch.

Selecting a point on the circle

To select a point on the intersection of the 2 spheres, we first computed a quaternion representing the rotation to apply on a unit vector. As the Z axis is pointing forward in the model, we can use a vector( 0, 0, 1 ) to compute the orientation: [...Notes:Inverse kinematics...]

Google maps space-time bubbles.png

Strange sensation when navigating in google maps' street view: the panoramic view changes radically when moving from a few meters. As if our world was made of space/time bubbles, reachable via jumps from one to another. The continuum is lost, without any problem for the computers behind. A twisted vision of reality that must affect the human one.
