GNOCHI: Generative Neural mOdel for Close Human‐Human Interactions

Computer Graphics Forum, EarlyView.
Abstract Creating realistic 3D human‐human interactions in virtual environments is challenging due to the high degrees of freedom in human body and the need for physically accurate poses that do not collide with each other. Traditional methods for humanhuman interaction are based on motion tracking or 3D body reconstruction, but lack generative ...
