Trinity is an audiovisual interactive dance piece which tells the journey of a body going through different states of perception of the space. Through movement, the body is immersed in an environment of textures and audiovisual landscapes that not only accompany but will push to a transformation process.

A transformation process achieved through the close link between the triad of movement, light and sound shaping a language that allows the expression of these elements in space, while causing profound changes in physical behavior to the body through the reverberation and echoes of its own actions.

The project focuses on working with the following parameters and qualities of movement: forces and directions, acceleration, position, speed and body area.

Its design has taken into account mainly the following aspects:

- Not to delimit the free movement of the performer.
- Obtain a clear and effective audio-visual system response.
- The three elements (movement, sound and visuals) must interact with each other.
- Dont saturate the interpreter or the viewer even with the high levels of interaction.

The interaction system works through a videocamera installed at top of the stage under infrared lighting.

How was MAX used?

This project uses MAX for everything. The performance is executed live using one MacBook Pro and MAX/MSP/JITTER to launch audio samples, realtime visuals done with Jitter and the interaction using CV.JIT with a PointGrey camera. The entire system runs smoothly at 60fps.

This is really really amazing! Are you opened to share the patches? Congratulations!!!!!!

Hi Eufrasio, thanks for your comment! :)
sorry but for diferent reasons i cant share the patch, but im more than open to share and answer any straight question about how is done…

is not important thet u sharre ur work , but will be important speak on
with little exaples

May 7, 2013 at 1:07pm

luxi, its easy, do your questions and i will be glad to answer all of them…

Fantastic piece! @carsol which particular PointGrey camera did you use?

May 8, 2013 at 5:22am

WOW! Amazing work.
I have a question; The visuals, are they generated using pre recorded animation or is it computer generated? if so, what Objects have you used to generate the visuals? I assume that you have used different effects on some basic shapes of some sort?

Again! Beautiful work! KUDOS!

Its a FireFlyMV. Very good relationship price/performance.
I use a couple of firewire repetares to get 25 meters long firewire connection. Cables and repetaters also from PointGrey.
Also take a look to Flea3 i hear that also is very responsive to NIR and a big advantage of GigE interface… much easier! but i guess must be expensive than FFMV…

thanks Ricardo!
all is Jitter and done in realtime without preproduced material. i think this is the way to achieve very high and responsive interaction.
what you see is from… plane point displacements using optical flow objects from cv.jit external, to simple textures coming from jit.bfg and paired to gl.ligh, the amazing external boids and a lighting torus… and the objects, the common ones.. gl.mesh, gl.gridshape etc… for effects i use the common shaders coming with Jitter to achieve feedbacks, bright/contrast and some displacements

Interesting. Cloud i ask at what resolution you render in And output?

May 9, 2013 at 3:45pm

yep.. 1600×1200

May 9, 2013 at 7:25pm

What projector did you use? Did you use IR for position tracking, if so, did you use an IR emitter with it? What kind?

Amazing work, looking forward to hopefully seeing more in the future!

Wow, nice! I m looking into jit.bfg. Thanks for the input.

the videoprojector was a panasonic pt5700 with 0.8 lens and i use 4 DIY focus with 70 850nm IR leds each to fill 9×7 meters stage (7m heigh)

Very inspiring. Now I’m looking at those cameras…

Sep 12, 2013 at 10:58am

Can I ask what type of lens you used on the camera? Did you purchase a glass IR filter or use a gel/polyester for the camera?
