DELTΔ , Echolyse / Olivier Ratsi

法国艺术家Olivier Ratsi在上次给gooood分享了超炫视觉声光装置Onion Skin之后，今次又给gooood分享了同样犀利震撼的视觉艺术装置DELTΔ。

Onion Skin和DELTΔ都属于Echolyse这个项目的一部分，Onion Skin是系列一，而DELTΔ是系列二。

Olivier Ratsi专注于人们基于现实的空间感知，他试验了一系列基于空间与时间的感知触发体验装置，为人们开启一个全新的视野体验感知领域。Echolyse项目是通过传统投影技术，让简单的几何元素实现并定义新空间，利用几何光效制造出“幻觉”场所。这个考虑现实，时间，空间，物质和感知的项目Echolyse，现有的两个系列Onion Skin和DELTΔ都是在同一理念下不同的形式实现。Onion Skin主要是通过在两面垂直相交的幕布上结合音乐投影出长达14分钟的4部分超酷图形化投影，以实现匠心独运，标新立异的空间感知。

DELTΔ则是通过在一个相对几何体区域中（人们只有站在固定视点才能看到它是三角或矩形，因为投影区域的表面是多个相交的面。）投影实现几何重构的视觉体验。至于为什么叫DELTΔ，那是因为Delta是希腊字母中第四个象形字母，由直立三角形符号表示，代表门。

Olivier Ratsi还告诉gooood，DELTΔ曾在台湾，中国，法国，德国展出过，而最近马上要参加法国的Transmient Festival 和斯洛文尼亚的Sonica Festival。

Echolyse
The Echolyse project considers objective reality, time, space and matter as intangible elements of information and uses these notions through installations that aim to question references to the perception of space.

The visual content – named “peelings”- is created from spatial data from the projection surface, according to the perspective observed by the viewer,from a specific point.

These forms, or “peelings”, are projected using a traditional mapping technique through the same projection surface of the installation. The whole experience of this project is based on the specific point of view. Once the viewer is positioned on the predetermined point of view, the “peelings” are revealed as anamorphosis that have dematerialized from their projection surface. The simple geometric elements, which at first seemed to be flat, suddenly begin to define a new space.
The illusion of a new dimension within the installation appears under different layers, which seem to leave their physical surface behind them.

This idea was implemented in different forms and formats: Onion Skin and Delta are the works, which show the project.

DELTΔ
Concept and visual content by Olivier Ratsi
Sound design: Thomas Vaquié
Production: Nicolas Boritch/Antivj
White painting, videoprojectors, loop duration: 4 minutes

Since ancient times, Delta, the fourth letter of the Greek alphabet, has been represented by a triangle pointing upwards. Originating from the equivalent letter of the Phoenician alphabet, it is based on a hieroglyph initially representing a door.

Delta, the second stage in the Echolyse project, is a site specific installation, that explores, through a dematerialised door, the possibility of a fictional three-dimensional space.

Making use of the anamorphosis technique, the piece is based on the position of the spectator,  predetermined by the artist, from which the audience will be able to visually reconstitute the geometrical symbol and discover the “pelures” (peelings) emitting from the very center of its gravity.

Onion Skin
Concept and visual content by Olivier Ratsi
Music: Thomas Vaquié
Production: Nicolas Boritch/Antivj
Two videoprojectors, duration:14 minutes, wood, 2 walls of 6.50 m x 3.50

The  first  stage  in  the  Echolyse  project,  which  will  also  give  birth  to  other  works,  Onion  Skin  is  made  up  of  a physical  dimension  –  a  module  of  two  walls,  positioned  at  right  angles  –  augmented  by  a  projection  and  a 5.1  sound  broadcast.

Onion Skin is a graphical work about the re-composition of time and space through a game of perspectives, both of the exhibition space itself and that of the projection canvas. Built around a progressive structure, made up of 4 parts lasting 14 minutes in total, the piece plays on the principle of repetition and scale to create a physical and hypnotic experience that opens doors onto the hidden and untouchable.

Onion Skin is augmented by a 5.1 sound broadcast that reinforces this impression of volume and space.

Olivier Ratsi

Olivier Ratsi is a French visual artist whose work is mainly based upon representations of space’s perception and the experience of reality.

He has developed creative concepts based on the deconstruction of space and time that act mainly as an emotion trigger, which does not aim at showing what things could be, but more at questioning their references.
Its aim is to generate a break from the meaning of the original items, to propose a new viewing point and provide the public with a new field of experience, a different way of looking at space and time.

In 2008, Ratsi has cofounded the visual label Antivj. His work has been published at New York Times Style Magazine and exhibited  at Elektra, BIAN, Montreal; Mapping Festival, Geneva; National Taiwan Museum of Fine Arts, Taiwan; Electronika Festival, Brazil; Gallery K11, China; Exit Festival, Paris; Multiplicidade FEstival, Rio de Janeiro; Proyecta Oaxaca Festival, Mexico; Art Beijing, Beijing.
