PFN Digital Asset Generation System:「リアル」「バーチャル」の概念を越えた先にある未来 (“A future in which the concepts of “real” and “virtual” have been transcended”)

This video, released Saturday, March 13, 2021, features an animated short produced by our studio, which accompanies the third digital single from virtual singer HACHI, 20. Main character design was based on characters created by the PFN-developed automated character generation system Crypko™. The smartphone and other background accessories were also created based on digital elements from PFN’s high-precision 3D model generation technology.

As part of our mission “to do what no other has done, in unparalleled quality, for all the world to see and enjoy”, we have sought to proactively implement the leading edge of technology for high-end video creation, and will continue striving to stay at the forefront of animation business development.
