In traditional 3D computer games, the user typically controls a character that moves around a virtual world. The virtual camera that films the action is often fixed relative to the character, providing a first-person perspective or a view from behind and above the character. As the character turns, the viewpoint turns as well. While effective, these camera angles represent only a small subset of the options available in cinematography.
To create a richer visual experience, we propose integrating more cinematographic principles into the design of virtual cameras. However, before we can fully explore these principles, it is crucial to understand the fundamentals of camera control in virtual environments. Therefore, this paper examines a range of techniques that address various challenges related to virtual camera control. Although our primary focus is on 3D computer games, the techniques discussed are also relevant to other virtual environments.
Camera Control Fundamentals
Fundamental techniques aim to position and orient the camera within the virtual world to generate still images. Some approaches enable the camera to provide moving shots, such as those used in virtual museum walkthroughs. More advanced methods focus on enabling the virtual camera to follow a moving subject, addressing common issues associated with this task. These foundational techniques are essential for developing more sophisticated camera control systems.
Cinematography-Informed Camera Control
Building on these fundamental methods, we explore approaches to camera control that draw from cinematography. These approaches not only enhance visual storytelling but also aim to evoke emotional responses from the user. By incorporating cinematographic techniques, we can create a more engaging and immersive experience for players.
The rest of this paper is structured as follows:
- Section 2: Introduces the principles of cinematography as they relate to camera control in virtual environments.
- Section 3: Discusses the fundamental techniques of camera control in virtual environments.
- Section 4: Outlines methods for controlling the virtual camera through cinematographic principles.
- Section 5: Provides a conclusion and outlines our future work.
By addressing these topics, we aim to present a comprehensive overview of camera control in 3D computer games and other virtual environments, highlighting the potential benefits of integrating cinematographic techniques.
