Switching virtual sources, often abbreviated as SVS, refers to a technique used in computer graphics and physics simulations to efficiently render or interact with virtual objects. Instead of calculating the full properties or interactions of every virtual object in a scene, SVS dynamically determines which objects are relevant to the current viewpoint or simulation. Only these relevant objects are then fully processed, while others are either simplified, ignored, or represented by less computationally intensive approximations. This selective processing dramatically reduces the computational load, allowing for more complex scenes or faster rendering speeds.

The core principle of SVS lies in the concept of "virtual sources." These virtual sources represent the origin of visual or physical effects. By identifying which virtual sources are actively contributing to the current view or simulation state, the system can focus its resources. For example, in rendering, if a virtual light source is far from the camera and its light is unlikely to illuminate any visible surfaces, SVS might choose to exclude it from the illumination calculations. Similarly, in physics simulations, if a group of virtual particles are far from a collision or interaction point, their individual movements might be approximated by a collective behavior rather than precise individual tracking. This approach is crucial for real-time applications like video games and virtual reality.
