摘要

实时天空渲染在许多3D应用的可视化中起着重要的作用。如果不考虑云层的影响和大气的散射效应，很难模拟出真实的天空。在本文中，我们使用物理散射模型来模拟天空，并使用柏林噪声纹理来创建高度逼真的云。通过将照明模型与各种大气成分相结合，还可以产生不同的天空效果。

An Efficient Approach to Real-Time Sky Simulation

Real-time sky rendering plays a great role on visualization in many 3D applications. It is difficult to simulate a realistic sky without considering the effect of clouds and the scattering effect of the atmosphere. In this paper, we use a physical scattering model to simulate the sky, and a Perlin noise texture to create highly realistic clouds. Different effects of the sky are also generated by combining the lighting model with various atmospheric constituents.
