Preludios Epigramaticos

The “Preludios Epigramaticos” were written in 1981 by the Cuban composer Leo Brouwer (1939- ), in what he called the “New Romanticism” phase. Inspired on poems by Miguel Hernandez, these small works employ minimalistic gestures, unusual time signatures, greek modes and recurrent intervals like 2nds, 4ths and 7ths in a rather somber atmosphere (except for a more cheery Preludio #4, which is reminiscent of popular Cuban music). They also appear to renounce to an established key or tonality, maintaining a center with independent melodic lines related to themselves through a musical idea.  Each one of them bears a fragment of a poem as subtitle.
The “Preludio Epigramatico # 1” employs all throughout the piece a rhythmic pedal (known as “Yambo”), made up by an interval of a minor 3rd (Si-Re, or B-D). It’s divided in 3 sections, A-B-A1 , and utilizes different greek modes/scales. Some interesting note groupings can be heard in the ascendant scale runs (5, 10 and the longest, 13 notes per beat). The score doesn’t have any time signature, but instead indicates a steady pulse of 1 crotchet = 60, reminiscent of a heart beat.

Through the development of the interfaces, trying to present anthropological behaviours and the emotions embedded to a wrestling mask design, I encountered that the technology was capable of transporting these sensations.  We usually see the wrestlers from outside their mask, but we have never seen how do they see us from behind the mask or how will it feel to be behind that mask.

Through augmented reality the potential of virtual elements can be expanded an fully teleported to the audiences location, it can embed intrinsic design elements into any object and allow that object to be fully visualised.

The primary objective was to generate a better understanding of the characteristics and behaviours of the wrestlers in the arena and their embedded qualities attached to their personas. Through these following examples, several outputs have been discovered along with several diverse technologies.

Augmented Reality

Augmented reality is a process in which a blending of several dimensions meet.  The digital and the physical objects meet together to generate a new augmented dimension.  Usually the any technology can be used to position an object on a plane and make it interact in several ways.

Total Immersion

Total Immersion is a company with presence in France, Germany, United Kingdom, Hong-Kong, Japan and in the USA.  They have developed several series of applications that allows the user to develop the most outstanding augmented reality objects.

The main issue with augmented reality is that most of the applications require a marquer for the augmented content to be displayed, Total Immersion provides robust 2D and 3D tracking, which means there is no need for a marker.  Avoiding to use a marker, can increase your creativity possibilities.  Check them out, since I believe they are the best in the field.

Alternate Options

As part of my personal research, I could not afford going to Paris and buy the applications from Total Immersion, so I decided to start working with what the community had to offer.  This forced me to work with the technologies that I currently had access to.  So I developed the applications in Flash based technology.  With the use of Papervision 3D, I managed to mount the content and I started using AIR for distribution.  Mainly the blend of ActionScript, Papervision and Spark can allow you to create these type of applications.


Get in the Ring

This augmented reality interface  will be able to position wrestlers in a wrestling ring (scale) and view, rotate and interact with them.

This video presents the process I went through to position the object along with the markers.

The second step was to be able to embed colour to the shapes. The use of Collada objects allows to place them with texturing on the Papervision 3D plane.  This experiments I attempted to see what happens if I move the object from the ground.  In this case the character in colour is on at the same height of where the ropes are going to be.  The other one is at ∆0.

AR Mask

The second experiment for augmented reality is to position a mask that can be able to be modified from the physical mask.  This has to start with a marker.

The process of using natural interfaces into the Augmented Reality interface are amazing, at this stage I am in the process of positioning the elements correctly at the time they become animated on the plane.

These experiments are still under development.  I am currently working on my audio virtual museum, which has made this project to be left out a little bit.  But more updates are coming out soon!

Flash and ActionScript 3.0

Lately I have been learning how to visualise data using ActionScript.  One of the most amazing things you can do is visualise audio.

You can be able to take any input to flash and let it analyse it, then you can decide what to do with that data.

Example 01 – Draw a line.

This example is using the microphone, so make sure you have one connected and make sure you allow Flash to connect to your microphone.

Example 02 – Circles

This example is just pulling a normal mp3 document form the web.  (   Flash is analysing the amplitude of the audio with the is transformed to a numerical value with will act as a radius for the circles.  Each circle is directly linked to a range of MHz, which then reacts to the amplitude as a radius.

Example 02a – Circles on a mask

This is exactly the same application of the previous exercise, but in this case I just placed a video feed as a background, just to have something more dynamic.  The circles now have a mask property, which makes the video visible only when the amplitude reacts to increase the radius of the mask circel

Here are other examples.
