Figure 1: 3PP-R allows the user to interact in 3rd-Person Perspective (3PP) using natural movements, including body rotation without losing sight of the avatar. A virtual display such as a 3D miniature world model hovers in air in front of the user, showing a 3rd-person avatar. When the user turns, the display orbits around the user but does not rotate except for the avatar. From the user's perspective, the display appears fxed in the feld of vision, and the world rotates around the avatar.

Cutscenes form an integral part of many video games, but their creation is costly, time-consuming, and requires skills that many game developers lack. While AI has been leveraged to semi-automate cutscene production, the results typically lack the internal consistency and uniformity in style that is characteristic of professional human directors. We overcome this shortcoming with Cine-AI, an open-source procedural cinematography toolset capable of generating in-game cutscenes in the style of eminent human directors. Implemented in the popular game engine Unity, Cine-AI features a novel timeline and storyboard interface for design-time manipulation, combined with runtime cinematography automation. Via two user studies, each employing quantitative and qualitative measures, we demonstrate that Cine-AI generates cutscenes that people correctly associate with a target director, while providing above-average usability. Our director imitation dataset is publicly available, and can be extended by users and film enthusiasts.
