Octree Structure

Octrees are hierarchical tree data structures that efficiently represent 3D data by recursively subdividing space into eight octants. Current research focuses on leveraging octrees for various applications, including 3D shape generation and reconstruction using diffusion models and neural networks, efficient scene representation for real-time rendering, and point cloud processing with state-space models and transformers. This adaptable structure offers significant advantages in memory efficiency, computational speed, and the ability to handle varying levels of detail, impacting fields like robotics, computer graphics, and cultural heritage preservation through improved 3D data management and processing.
