Real-time shader-based shadow and occlusion rendering in AR

We present novel methods designed to elevate the realism of augmented reality (AR) applications focusing specifically on optical see-through devices. Our work integrates shadow rendering methods for multiple light sources and dynamic occlusion culling techniques. By creating custom surface shaders we can manage multiple light sources in real-time, augmenting depth perception and spatial coherence. Furthermore, the dynamic occlusion culling system handles occluded objects, ensuring a more convincing and seamless user experience. Several cases and methods are presented with their re-sults for various lighting and spatial conditions, promising a more enhanced and immersive user experience in various AR domains.
