我们提出了一个可视化工具，专门针对光子地图去噪方法的开发和优化。我们的工具允许通过使用平行坐标、特定领域的脚本、颜色映射和点图来快速测试假设和算法。通过刷动、调整参数和焦点加上下文进行交互，并产生交互式视觉反馈和调试信息。我们演示了使用该工具来探索高维光子映射数据，促进发现可用于分离复杂焦散照明的新参数空间。然后，我们将展示如何使用这些新的参数化来改进光子弛豫框架中已有的噪声去除方法。
We present a visualization tool aimed specifically at the development and optimization of photon map denoising methods. Our tool allows the rapid testing of hypotheses and algorithms through the use of parallel coordinates, domain‐specific scripting, colour mapping and point plots. Interaction is carried out by brushing, adjusting parameters and focus‐plus‐context and yields interactive visual feedback and debugging information. We demonstrate the use of the tool to explore high‐dimensional photon map data, facilitating the discovery of novel parameter spaces which can be used to dissociate complex caustic illumination. We then show how these new parametrizations may be used to improve upon pre‐existing noise removal methods in the context of the photon relaxation framework.
