👉 The `ll:light_particles` in this context refers to the representation of light particles within a computational or simulation framework, likely in a physics engine or a related software application. These light particles are small, discrete entities used to simulate the behavior of light in a scene. They can model various aspects of light, such as photons, which are the fundamental particles that make up visible light. Each light particle typically has properties like position, velocity, color (represented by a spectrum or color model), and intensity. By tracking and interacting these particles, simulations can accurately render effects like reflection, refraction, and shadows, creating realistic lighting conditions in virtual environments. This approach allows for efficient computation of complex lighting phenomena, enabling detailed and dynamic visual experiences in movies, video games, and other visual media.
