Virtuaalikamera refers to a virtual camera, a software-based tool that simulates a physical camera within a digital environment. This technology allows users to capture and manipulate imagery that does not originate from a real-world camera lens. Instead, it generates video feeds from software applications or game engines.

Virtual cameras are widely used in various fields. In video conferencing and streaming, they enable users to share their screen content, pre-recorded videos, or custom graphics as if they were a direct camera input. This is achieved by capturing the output of a program and routing it to other applications that expect a webcam feed. For example, a user might use a virtual camera to display a presentation from a slideshow application or a gameplay stream.

In the realm of 3D graphics and animation, virtual cameras are fundamental. They define the viewpoint from which a scene is rendered, controlling perspective, focal length, and camera movement. This allows animators and visual effects artists to create dynamic and compelling shots without needing physical cameras. The "camera" can be moved, rotated, and manipulated programmatically within the 3D space.

The implementation of a virtual camera typically involves creating a software driver that acts as a bridge. This driver captures frames from a source application and presents them as a video stream to other applications, such as OBS Studio, Zoom, or video editing software. This abstraction layer provides flexibility and control over digital visual content creation.
