October 2020: Generative art - Vector field based virtual sculpture
NGC
At the occasion of the moving of their headquarters to Toyosu, the company NGC asked me to create a variation of one of my content so it can be placed in their lobby.

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.
