Real-time rendering

Definition

Real-time rendering is the process of generating and displaying images quickly enough to allow interaction, often at a minimum of 30 frames per second. This technology is crucial in creating immersive experiences, enabling artists and developers to blend live action with digital effects seamlessly, and providing immediate feedback during performance capture or animation.
