Large-Scale Distributed Virtual World Systems
Explore the technical challenges and innovative solutions for building scalable and efficient large-scale distributed virtual world systems, featuring advanced techniques for aggregation, simplification, and coordination.
- Large-scale Distributed Virtual World Systems: The talk highlights the challenges of building a virtual world system, emphasizing the need for scalable and efficient solutions.
- Aggregation Across Large Servers: The concept of aggregation is crucial in simplifying complex geometry and reducing the number of objects to render.
- Instance-Aware Simplification: Instance-aware simplification helps reduce the complexity of instances by simplifying their geometry.
- Coordination Segmentation: Coordination segmentation services coordinate the movement of objects across servers, ensuring consistency and reducing lag.
- Region-Based Partitioning: Region-based partitioning divides the virtual world into regions, allowing for efficient query processing and management.
- Fair Queuing: Fair queuing ensures that all objects receive equal processing time, preventing bottlenecks and ensuring a smooth experience.
- Discretization: Discretization involves breaking down geometry into smaller, manageable pieces to improve performance.
- Object Segmentation Service: The object segmentation service takes care of object decomposition, making it easier to manage complex geometry.
- Quadric Simplification: Quadric simplification reduces the complexity of objects by simplifying their geometry.
- Pinto: Pinto is a system that answers geometry queries by maintaining a spatial index.
- Geometric Query: Geometric queries involve asking for specific information about objects in the virtual world, such as visibility or proximity.
- World Time: World time refers to the serialization of objects across servers, ensuring consistent updates.
- Positioning and Rotation: Positioning and rotation are crucial aspects of object interaction, as they enable precise movements.
- Texture Aliasing: Texture aliasing involves reducing texture size to improve performance and reduce lag.
- Scripting Language: A scripting language allows for the creation of custom logic and behavior in objects.
- Object Host: The object host is the entity responsible for maintaining and updating objects in the virtual world.
- Space Server: Space servers manage the geometry of objects and handle query processing, ensuring efficient rendering.
- Data Structure: A data structure called the bounding volume hierarchy (BVH) is used to simplify and accelerate query processing.
- Physics Interaction: Physics interaction involves simulating real-world physics in the virtual world, such as collisions and dynamics.
- Content Distribution Network: A content distribution network (CDN) distributes and caches content to reduce latency and improve performance.
