Sparse Cache Updates for Scalable Distributed Effect-Based Rendering

Abstract summary

This system shares shading work across people viewing the same virtual environment from different perspectives. Surface-based caches allow rendering tasks to be distributed across several GPUs while reusing computed lighting. Instead of sending complete frames between devices, the system transfers selected cache updates, reducing communication as the number of viewers grows.
