这件艺术装置呈现了一种半物质的存在方式，利用光来物化出具体的形象。“光屏第三版本”是该系列的最新成员，它在物质与非物质、现实与幻觉以及存在与虚无的边界中建立了一种混淆与不一致性。

The installations present a semi-material mode of existence, materializing objects from light. Light Barrier Third Edition is a new installment in this series that exploits the confusion and non-conformities at the boundary between materials and non-materials, reality and illusion, and existence and absence.

装置以圆形为基调，用6分钟的时间游历了有关于诞生、死亡与重生的主题，帮助观众进入一种全新的存在形式。艺术家利用工作中常见的圆形来唤起物质的本质，以及生命与死亡之间的外在关联。

The 6-minute sequence employs the motif of the circle to travel through themes of birth, death, and rebirth, helping shift the audience into the new mode of existence. The artists use the circle often in their works to evoke the fundamentals of materials and the external connection between life and death.

艺术家感兴趣于印象派画家如何受到摄影技术的启发，从而创造出“无观察者的影像”。装置令这些影像脱离画布，成为存在于透视之外的画卷。这是艺术家对“在空中绘画”这一主题进行的一次直接尝试。

The artists are interested in how impressionist painters were inspired by the introduction of photography to create ‘viewer-less images’. The installation allows images to arise from the canvas, creating painting outside of perspective. It is a direct approach to the artists’ theme of “drawing in the air”.

在这一版本中，借助人工自然原理，8个以建筑学手法制作的投影装置被一个由凹透镜组成的结构分裂为630个小投影器。每个镜面及其衬垫结构皆经由计算生成，共同组合为一个整体，在空中投放出一个单块的影像。通过对16,000,000个像素点分别进行精确校准，这些光柱得以穿透薄雾绘制出图像。40段音频被用以构建出一个声场，使投影现象更加具体凝固地深入观众的内心世界。

In this edition, 8 architectural video projectors are split into 630 sub-projectors using a structure of concave mirrors designed by artificial nature. Each mirror and its backing structure are computationally generated to create a group that collaborates to form the single image in the air. By accurately calibrating each of the 16,000,000 pixels individually, light beams can be merged in the haze to draw in the air. 40 channels of audio are then used to build a sound field that helps to solidify the projected phenomena in the audience’s mind.

光屏第三版本由光州的亚洲文化中心委托设计，其制作工艺通过Kimchi and Chips为空间校准设备创建的开源图形工具Rulr得以实现。

The third edition of Light Barrier was commissioned by the Asia Culture Center in Gwangju. The technology is enabled by Rulr, an open source graphical toolkit for calibrating spatial devices, created by Kimchi and Chips.
