SCENE DATA SYNCHRONIZATION IN SORT-FIRST RENDERING SYSTEM FOR LARGE DYNAMIC SCENES

In this paper we built a cluster-based sort-first rendering system. Unlike previous sort-first rendering systems for static scenes, ours can cope with large dynamic scenes with massive data. A set of strategies are designed and implemented to give solutions for scene data synchronization in our system. The experimental results show that our system maintains favorable data consistency for dynamic scenes and is highly scalable with solid improvement of rendering performance. Using 16 computing nodes, our system can achieve interactive visualization result in the test physical simulation scene which contains 10,000 moving rigid-body models and building models with massive geometric and texture data.
