September 2023: Immersive installation at Bandai Spirits in Tokyo
NGC / Bandai Spirits
Director / Technical director / Developer

  • Interactive content design
  • Sensing system development
  • Sound design
  • Floor lighting system development

  • This immersive experience was installed at the entrance of BANDAI SPIRITS headquarters in Tokyo. The setup consists of two 6.5m-long LED screens on both sides of a corridor.

    Depending on the season, different contents are shown. Optical sensors allow these real-time interactive contents to respond to people's movements.
    April 2023: Skull mesh reconstruction (medical field)
    Undisclosed client
    Consultant / Software Engineer

    This project focused on developing a specialized software solution for reconstructing skull meshes in the medical field. Besides the physical limitations of the scanner (only a limited area of the skull can be captured in each scan), the software aligned and merged the multiple partial scans. This proved challenging at times, particularly because of the patient's head movements during the scans.

    'Path of Noise (r, theta, phi)' received the Festival Platform Award Geo-Cosmos category at the Japan Media Arts Festival.
    In this artwork, particles are moving along the surface of a sphere and are tracing curves along their passage. The movement of the particles is a symbolization of the randomness of one's life and its chaotic path.
    The content is generative, in other words, different patterns and colors appear for each iteration.

    A quite challenging aspect of this project was using a sphere-shaped screen (6-meter-diameter). Because there is no border, there is neither a beginning nor an end. The particles can move in all directions and loop around the sphere.

    Although it is generative content, I also wanted to tell a story. The artwork is composed of several parts in which I tried to put different moods. Recent years have been difficult for many people around the world. I wanted to express some hope and bring some comfort into the heart of the viewers. That's the reason for using cherry blossoms.
    March 2021: Installation of a 22 multi-screen solution at 19M Chanel in Paris
    Dalbin Studio / Parallel Architecture

    Though the system was initially conceived in order to play multiple video contents synchronized over multiple computers, a very special requirement for this installation was on the contrary the videos to be played randomly and avoid any impression of looping.
    Janvier 2021: House of Progress Audi Omotesando
    Gradation / MontBlanc Pictures
    Technical Director

  • Technical direction
  • Design of the content production workflow and the templates
  • Calibration

  • This project proved to be quite challenging, primarily due to the subtle contours shaping the car's design. Achieving perfect alignment of the projection with the car was crucial to ensure visual consistency and coherence.

    In addition to overseeing the technical aspects of the projection mapping, I was also in charge of establishing a workflow for the content team to develop their materials, as well as handling the calibration of the projection.
    December 2020: Talk at Motion Plus Design World / Japanese Edition
    Motion Plus Design

    A Story About Face And Body Projection Mapping

    During this speech, I talk about the experiences and inspirations that led me to my work on face projection mapping and body projection mapping.

    October 2020: Generative art - Vector field virtual sculpture

    At the occasion of the moving of their headquarters to Toyosu, the company NGC commissioned me for a variation of one of my content.

    Displayed on 4 curved screens, the content evolves and changes perpetually. Colors and shapes, as well as camera work are generated randomly in real-time.
    May 2020: Parted - Body Tracking and Projection Mapping (Personal project)
    Daisuke Hashimoto / Paul Lacroix / Yae Doi / Mari Katayama
    Creative Technologist

  • Technical direction
  • Creation of a system (hardware & software) able to smoothly track the performer body and accurately project video animations fitting the body shape

  • After several years experimenting on body projection mapping, this collaboration between Daisuke Hashimoto, Yae Doi and me represents a new step in the field of body projection mapping. The video is starring the Japanese artist Mari Katayama.

    Besides the cutting-edge technical aspect, we tried to create a peculiar visual, strongly inspired by the Japanese painter Ito Jakuchu. We also question the relation between identity and technology, as well as the perception of beauty and taboo within our societies.
    May 2019: Markerless Face Projection Mapping on Bilal Hassani at Eurovision 2019
    French Delegation for the Eurovision / Takeru Shima (CG)
    Technical Director / Technology Developper

  • Technical direction
  • Customization of the markerless face projection system for live conditions

  • Eurovision Song Contest is a huge broadcasted live event followed by 200 million viewers. Part of the French delegation, I was in charge of the Face Projection Mapping. The system had to be installed on stage in only 40 seconds, so all calibrations and tests had to be completed before. I customized and optimized the system in order to increase its robustness for such a live event. The video is a little bit dark as the lighting technician forgot to switch on the backlights during the face projection, but the face tracking and projection mapping itself went well.

    April 2019: The Lady in the Wood (Personal project)
    Paul Lacroix / Ryosuke Makita / Yae Doi
    Director / Technology developper

  • Direction, content creation
  • System development

  • Before this project, most of my facial projection mapping videos were shot in studio or at least in a location with easy access to electricity and light. The Lady in the Wood is an experiment aiming to evaluate the feasibility and robustness of using markerless face detection system in an uncontrolled environment. The video was shot in a small forest near Mont Fuji.
