标题： Real-Time Rendering of Dynamic Line Sets using Voxel Ray Tracing

摘要： 实时渲染动态线集在许多可视化任务中都很重要，包括非定常流可视化和从磁共振成像中交互式白质重建。高质量的全局光照和透明度对于传达密集线集的空间结构很重要，但在交互速率下仍然难以实现。我们提出了一种高效的基于体素的光线追踪框架，用于渲染具有环境遮挡和真实透明度的大规模动态线集。该框架引入了一个体素化算法，支持对体素锥追踪和光线追踪的加速结构进行高效构建。为了进一步降低每帧的预处理成本，我们开发了一种基于体素的剔除方法，将加速结构构建限制在相机可见的体素上。这些贡献共同实现了具有物理准确透明度的大规模动态线集的高质量实时渲染。结果表明，当渲染（半）不透明动态线集时，我们的方法在质量和性能方面优于现有技术。 显示英文摘要

摘要： Real-time rendering of dynamic line sets is relevant in many visualization tasks, including unsteady flow visualization and interactive white matter reconstruction from Magnetic Resonance Imaging. High-quality global illumination and transparency are important for conveying the spatial structure of dense line sets, yet remain difficult to achieve at interactive rates. We propose an efficient voxel-based ray-tracing framework for rendering large dynamic line sets with ambient occlusion and ground-truth transparency. The framework introduces a voxelization algorithm that supports efficient construction of acceleration structures for both voxel cone tracing and ray tracing. To further reduce per-frame preprocessing cost, we developed a voxel-based culling method that restricts acceleration structure construction to camera-visible voxels. Together, these contributions enable high-quality, real-time rendering of large-scale dynamic line sets with physically accurate transparency. The results show that our method outperforms the state of the art in quality and performance when rendering (semi-)opaque dynamic line sets.
