Although an important component of natural scenes, the representation of skyscapes is often relatively simplistic. This can be largely attributed to the complexity of the thermodynamics underpinning cloud evolution and wind dynamics, which make interactive simulation challenging. We address this problem by introducing a novel layered model that encompasses both terrain and atmosphere, and supports efficient meteorological simulations. The vertical and horizontal layer resolutions can be tuned independently, while maintaining crucial inter‐layer thermodynamics, such as convective circulation and land‐air transfers of heat and moisture. In addition, we introduce a cloud‐form taxonomy for clustering, classifying and upsampling simulation cells to enable visually plausible, finely‐sampled volumetric rendering.

Skyscapes的交互式中尺度模拟

虽然是自然场景的重要组成部分，但天空景观的表示通常相对简单。这在很大程度上可以归因于支撑云演化和风动力学的热力学的复杂性，这使得交互式模拟具有挑战性。我们通过引入包含地形和大气的新型分层模型来解决这个问题，并支持高效的气象模拟。垂直和水平层分辨率可以独立调整，同时保持关键的层间热力学，例如对流环流和陆地空气热量和水分的传递。此外，我们引入了一种云形式分类法，用于对模拟单元进行聚类、分类和上采样，以实现视觉上合理的、精细采样的体积渲染。
