论文摘要
签名的距离字段（SDF）是在计算机图形中广泛使用的表面表示形式，在渲染，碰撞检测和建模中具有应用。在游戏（例如游戏）中，高分辨率SDF通常是离线生产的，然后将其加载到应用程序中，仅代表刚性网格。这项工作开发了一种新颖的技术，将跳跃洪水和射线追踪结合在一起，实时产生近似的SDF。我们的方法可以产生相对准确的场景表示，以呈现柔和的阴影，同时保持交互式框架速率。我们将以前的工作扩展到有关设计和实施的详细信息以及该技术的视觉质量和性能评估。
Signed distance fields (SDFs) are a form of surface representation widely used in computer graphics, having applications in rendering, collision detection and modelling. In interactive media such as games, high-resolution SDFs are commonly produced offline and subsequently loaded into the application, representing rigid meshes only. This work develops a novel technique that combines jump flooding and ray tracing to generate approximate SDFs in real-time. Our approach can produce relatively accurate scene representation for rendering soft shadows while maintaining interactive frame rates. We extend our previous work with details on the design and implementation as well as visual quality and performance evaluation of the technique.
