Xiangyan Tournesol – Technical Analysis (1/3)

First exhibition: March 2020, CO-EXISTENCE.S, GALERIE COMMUNE, Tourcoing, France[more]

Intro:
Xiangyan Tournesol is an interactive art installation created by contemporary artist Xiangyan. As technical support, Mingcong was mainly responsible for the complex technical implementation of the work. When different numbers of viewers approach from different directions, stop to watch, and explain the sunflower, the works will show different reactions. This article will introduce the work from three key technical perspectives.

  • Holographic Display Technology

It should be noted that the holographic display technology here refers to the hologram illusion based on light reflection, which is similar to Pepper’s ghost. This technology is currently mostly used in studio lifts or theater performances. We installed a transparent plate made of 4 pieces of acrylic material on the top of the work to form a pyramid-like shape. This shape is widely used for lightweight hologram illusion. And a monitor was placed under this inverted pyramid so that the acrylic sheet above could reflect what was on the screen below.

The difficulty here is how to construct a reasonable 4-view video and render it in real time. To achieve this, we asked artists to model and animate in 3D software and use Unity as the real-time rendering engine. According to the appropriate artistic effect, calculate the appropriate picture output method. The final result is a three-dimensional sunflower.
