摘要:
近年来提出的云的真实感绘制算法大多采用纹理操作进行绘制,绘制算法复杂,渲染过程较长,对计算机硬件的要求高,不能完全满足飞行仿真的实时性要求。为解决上述问题,从光的单一散射出发,考虑云和大气粒子引起的光衰减率,采用阴影切片的方法分割体数据,在太阳照射方向上和视点观察方向上对切片数据进行分析,从而快速绘制出真实感三维云。仿真结果表示,生成的三维云效果真实,具有良好的实时性,能够满足飞行仿真及其他领域的要求
Abstract:
Many algorithms were presented to rendering 3D cloud, but most of them are difficult to compute, and cannot meet the demand of real-time rendering in flight simulation. An efficient rendering method is proposed for rendering of clouds. The method creates images of clouds processing photo realism by taking into account the single scattering of light. Considering the light attenuations in both the sun direction from the sun and the viewing direction,using a method called shadow-view slices(SVS) calculate the attenuations to rendering the cloud. The result indicates the method provides a better 3D cloud rendering, and it can meet the demands of flight simulation and other fields
