由计算机图形学生成的室外场景的合成图像通常包含天空作为背景。天空的出现在增强场景的真实感方面起着重要作用。在本文中，我们提出了一个直观和交互的合成天空图像的系统，该系统能够反映用户的意图。我们的系统由两个步骤组成。第一步是天空生成步骤。天空的亮度分布和颜色是使用我们直观的用户界面生成的。第二步是云合成步骤。我们已经准备了一个真实云层照片的数据库。我们的系统在数据库中搜索适合合成天空的云图。用户在搜索结果中选择云，并将它们合成到天空图像中。通过使用我们的系统，用户可以轻松地生成所需的天空图像。
Synthetic images of outdoor scenes generated by computer graphics usually contain the sky as background. The appearance of the sky plays an important role in enhancing the reality of scenes. In this paper, we propose an intuitive and interactive system for synthesizing sky images that can reflect the user's intention. Our system consists of two steps. The first step is a sky generation step. The luminance distribution and colors of the sky are generated using our intuitive user interface. The second step is a cloud composition step. We have prepared a database of photographs of real clouds. Our system searches the database for cloud photographs that are suitable for the synthesized sky. The user selects the clouds in the search results and they are composited into the sky image. By using our system, the user can easily generate desired sky images.
