face replace

Sat, 15 Dec 2012 00:00:00 -0800

By Gabriel Dunne and Toby Shachman.

Created and shown over 36 hours during ArtHackDay "Lethal Software" at GAFFTA, December 15, 2012.

Physical installation built with a pre-existing art frame prototype. Viewers experience the work as a large portrait mirror, and they see a face superimposed onto their own in real time. Viewers can take a snapshot of their own face which immediately becomes superimposed onto their own. As people view the mirror, subsequent people have their faces replaced by the previous viewers faces.

A physical knob enables viewers to explore faces people have saved.

Sourcecode on github: https://github.com/quilime/face-replace

Built with OpenFrameworks and ofxFaceTracker and based on examples in FaceSubstitution.

Live visuals. Music Performer: Chris Carlson @ CCRMA Modulations 2012

this visual set was based on live-coding experiments with non-periodic tiling patterns. I'm still fascinated with the forms. Towards the end of the night I started using color.

visual software created with: audio-shadertoy

for this setup, the live audio was analyzed by ChucK through the built-in mic on my macbook air. the ChucK script routes osc to Node, and the client receives via web sockets.

because osx-style full-screen multi-monitor support is completely broken in OSX Lion, we couldn't use chrome. so we stripped out all the chrome-only webaudioapi stuff, and replaced it with an osc receiver. This allowed us to analyze the audio with an external interface and use any browser that supports webgl canvas, and does multi-monitory fullscreen correctly on osx. we ended up using firefox.

DualBoot Archlinux/Windows7 Installation

Mon, 02 Jan 2012 00:00:00 -0800

Documentation of the process of installing archlinux and Windows 7 in a dual-boot configuration.

System Specs

AMD X2 dual-core processor, running at 2.8 ghz, circa 2002
ASUS ATX motherboard
2 gigs of ram
100gb drive
nvidia gtx 550 ti graphics card
linksys wmp54g wireless pci network card
550w power supply

Installing Windows

Windows was installed from a USB stick using Microsoft's Windows 7 USB/DVD tool. It's required to create this key from a Windows 7 system. Boot with the USB drive, then install Windows on the drive in a single partition. Windows also creates a System Reserved partition for itself. Once installed, via Start Menu > Administrative Tools > Computer Management > Disk Manamagent, select 'Shrink Partition' on the main Windows parition to create another partition for Arch. The default value for the shrink is 50%, so for my setup the value for the new disk size was ~50GB, which was ideal.

Note about this install. I have an old Linksys (Cysco) WMP54G Wireless PCI Card. Drivers from Linksys/Cysco's website didn't work, but following this blog post, the generic RALink drivers worked great.

Installing Archlinux

I downloading the Core Image via torrent from http://www.archlinux.org/download/. This ISO includes all core packages so the system doesn't need to be online to install.

Once downloaded, I followed the notes on how to create a bootable ISO onto another USB drive with yet another machine. There are also numerous free tools available to make a bootable ISO on Windows. After booting into Arch with the USB stick, boot into Arch, and type:

/arch/setup

The installation article on the archwiki is an excellent resource.

Disk Partitions

It's pretty straight forward until the drive partitions. My 100GB drive can only support 4 logical partitions, so the rest have to be Logical. Note: The numbers are out of order, because I used Logical partitions for everything except for the Windows partitions and /home. Logical partitions end up being counted last in the partition table, but I made my /home folder LAST so I could use the up the remaining space on the drive. You'll also need to set the /boot partition's 'bootable' flag to true.

• sda1
    Windows 7 System Reserved
• sda2
    Windows 7
• sda5
    /boot - 100MB is enough
• sda6
    / - about 25GB is appropriate
• sda7
    swap - between 1024MB and 4096MB
• sda4
    /home - use rest of hard drive

Some of these, namely boot, swap, and home, are optional.

Select Packages

At minimum, you'll need the core packages that are already selected. I also included certain key packages such as OpenSSH. Basically, include any packages you need for internet connectivity, as everything else will be updated from the net.

Configure System

Configure system does multiple things, including setting the root password, network settings, and some other configuration tools. Here's a reference of where Arch installs all the base config files for the system.

/etc/rc.conf                    system config
/etc/fstab                      filesystem mountpoints
/etc/mkinitcpio.conf            initramfs config
/etc/modprobe.d/modprobe.conf   kernel modules
/etc/resolv.conf                dns servers
/etc/hosts                      network hosts
/etc/locale.get                 glibc locals
/etc/pacman.conf                pacman.confg
/etc/pacman.d/mirrorlist        pacman mirror list

You should edit any of these files that are specific to your system. At minimum I enabled my network card in rc.conf.

You'll also need to enable at least one mirror in pacman.d/mirrorlist if you plan to update the system or download new packages.

Bootloader

Install Bootloader will install and help you configure the bootloader you selected in the Select Packages stage (GRUB, in my case). After double-checking your bootloader configuration, you'll be prompted for a disk to install the loader to. You should install GRUB to the MBR of the installation disk, in this case sda1.

Finalizing Installation

Once installed, exit the installer, remove the USB, type reboot in the command line, and the system will reboot. You'll boot into a login screen, which you can login with via root.

You can create new users interactively with useradd.

You can install/update packages with Arch's package manager, pacman.

Before installing any packages, sync the package list with:

pacman --sync --refresh

To add a new package (vim, in this case), type:

pacman -S vim

next: getting node and a webserver installed.

print formatted JSON, XML from osx command line

Mon, 14 Nov 2011 00:00:00 -0800

Working with various interfaces that output json or xml results in lots of situations where you have a single-line, unformatted output. Here's a quick way to format json, xml from the CLI.

via the command line:

format json

cat unformatted.json | python -m json.tool

format json from clipboard

pbpaste | python -m json.tool

format xml from clipboard

pbpaste | xmllint --format -

xmllint is part of libxml2 and installed by default on OSX. Be aware that xmllint cleans up XML as well as formatting it, ocassionally modifying the output.

for all above examples, you can pipe back to the clipboard with | pbcopy at the end of the command, or output to a file with > output.json or > output.xml.

command line audio on OSX

Wed, 09 Nov 2011 08:40:26 -0800

Since there is no equivilent to /dev/dsp or /dev/audio on OSX, you need to install an alternative like sox.

Install sox by either downloading the OSX binary from http://sox.sourceforge.net/ or install homebrew, and then install sox with brew install sox

Examples

cat audio from /dev/urandom/ :

cat /dev/urandom | sox -traw -r44100 -b16 -u - -tcoreaudio

audio from an executable

cat > test.c
main(t) {
  for( t = 0;;t++)
    putchar( t * ((( t >> 12 ) | (t >> 8)) & (63& (t >> 4 ))));
}

[ctrl-c]

gcc test.c -o test
./test | sox -traw -r8000 -b8 -u - -tcoreaudio

islands

Wed, 05 Oct 2011 15:53:55 -0700

Imagine that every man's mind is an island, surrounded by ocean. Each seems isolated, yet in reality all are linked by the bedrock from which they spring. If the ocean were to vanish, that would be the end of the islands. They would all be part of one continent, but their individuality would be gone.

childhoods end

Wed, 05 Oct 2011 15:17:57 -0700

The case of India is particularly instructive. The main difference between us and the British in India was that they had no real motives for going there—no conscious objectives, that is, except such trivial and temporary ones as trade or hostility to other European powers. They found themselves possessors of an empire before they knew what to do with it, and were never really happy until they had got rid of it again.

Kali → goddess of eternal energy. The goddess of time and change. The ultimate reality.

The Sri Chakra or Shri Yantra of Tripura Sundari is a yantra or mandala formed by nine interlocking triangles surrounding the bindu. Four of these triangles are orientated upright representing Shiva or the Masculine. Five of these triangles are inverted triangles represent Shakti or the Feminine. Because it is composed of nine triangles, it is also known as the Navayoni Chakra.[1]

sri yantra guides

Together the nine triangles are interlaced in such a way as to form 43 smaller triangles in a web symbolic of the entire cosmos or a womb symbolic of creation. Together they express Advaita or non-duality. This is surrounded by a lotus of eight petals, a lotus of sixteen petals, and an earth square resembling a temple with four doors.[1]

The Shri Chakra is also known as the nava chakra because it can also be seen as having nine levels. Each level corresponds to a mudra, a yogini, and a specific form of the deity Tripura Sundari along with her mantra. These levels starting from the outside or bottom layer are:[1]

Trailokya Mohana or Bhupara, a square of three lines with four portals
Sarvasa Paripuraka, a sixteen-petal lotus
Sarva Sankshobahana, an eight-petal lotus
Sarva Saubhagyadayaka, composed of fourteen small triangles
Sarvarthasadhaka, composed of ten small triangles
Sarva Rakshakara, composed of ten small triangles
Sarva Rohahara, composed of eight small triangles
Sarva siddhi prada, composed of 1 small triangle
Sarvanandamaya, composed of a point or bindu

The Sri Chakra (called the Shri Yantra) is the symbol of Hindu tantra, which is based on the Hindu philosophy of Kashmir Shaivism.

Vijnanamaya — spiritual body composed of prayer and fortified by meditation

Anandamaya — body of the joy of union with god

—he who realizes the truth of the body can then come to tknow the truth of the universe

Payodhi-jala — primordial waters, force of the manifested universe

A fourth dimension of aesthetic sense, where all is in ourselves, ourselves in all —Aurobindo

Tantra: analogies between the individual and the cosmos, and the life forces which govern them

reflections of what is taking place in real life and reminding thought visions of our true nature

Jellyfish

Thu, 01 May 2008 00:00:00 -0700

Organic forms react to the user and each other. Their motions and position in space create and/or affect audio. A tenticles depth in space is correlated to volume, while its color is linked to a tone in the audio spectrum. Interaction with the tentacle instrument is smooth, undulating, jellyfish-like.

process selection list

string $select[] = ls -sl;
for ( $node in $select ) // process each
{
   /* ... */
}

if node exists

string $node = "object";
if ( objExists $node )
{
   // The node exists
}

regexp

Strip component

string $node = "pCube1.f[2]";
string $no_component = match "^[^\.]*" $node;
// Result: "pCube1" //

Extract component or attribute, with '.'

string $node = "pCube1.f[2]";
string $component = match "\\..*" $node;
// Result: ".f[2]" //

string $nodeAttr = "blinn1.color";
string $attrName = match "\\..*" $nodeAttr;
// Result: ".color" //

Extract attribute name, without '.'

string $node = "pCube1.f[2]";
string $component = `substitute "^[^.]*\\." $node ""`;
// Result: "f[2]" //

string $nodeAttr = "blinn1.color";
string $attrName = `substitute "^[^.]*\\." $nodeAttr ""`;
// Result: "color" //

Extract parent UI control from full path

string $uiControl = "OptionBoxWindow|formLayout52|formLayout55|button6";
string $uiParent = substitute "|[^|]*$" $uiControl "";
// Result: OptionBoxWindow|formLayout52|formLayout55 //

Strip trailing Line Break (\n), if any.

This is useful when processing text input read from a file using fgetline.

string $input = "line\n";
$string $line = match "^[^(\r\n)]*" $input;
// Result: "line" //

Extract directory from path.

Keep the trailing slash for ease of use.

string $path = "C:/AW/Maya5.0/bin/maya.exe";
string $dir = match "^.*/" $path;
// Result: "C:/AW/Maya5.0/bin/"

Extract file from path

string $path = "C:/AW/Maya5.0/bin/maya.exe";
string $filepart = match "[^/\\]*$" $path;
// Result: "maya.exe"

Strip numeric suffix



string $node = "pCube1|pCubeShape223";
string $noSuffix = match ".*[^0-9]" $node;
// Result: "pCube1|pCubeShape"

Extract numeric suffix

string $node = "pCube1|pCubeShape223";
string $suffix = match "[0-9]+$" $node;
// Result: "223" //

Extract short name of DAG or control path

string $dagPath = "pCube1|pCubeShape223";
string $shortName = match "[^|]*$" $dagPath;
// Result: pCubeShape223 //

Human generated tones are rendered with lines. The software manipulates these tones via random visual noise, making both audio and visual more chaotic of time. Tones start rigid and rhythmic, slowly degenerating into an organic, complex and chaotic system of overlapping frequencies and polyrhythms.

Rattles

Tue, 02 May 2006 00:00:00 -0700

Particles are jostled and shaken as in a rattle. The sonic possibilities of their collisions and movement are given freedom and sonic depth via software. Rattles and shakers can be embedded into one another, allowing for more sensitivity, sonic subtlety, and layers when making music. Interaction with the digital rattle is as intuitive as its physical counterpart.

The interaction with "Rattles" is identicle to the traditional percussive instrument. The visual shape, texture, or size of each interior rattler represents a unique audio tone, either percussive or melodic. The resulting soundscape of the rattle instrument is therefore unique and rich with sonic subtlety and variation, transforming the traditional "rattle" into an instrument with a necesarry visual component. Rattles can be embedded into one another, allowing for more sensitivity, sonic subtlety, and layers.
