Method of Rendering Clouds Based on Simplex Noise
WANG Shuai, JI Yu-bo
Three-dimensional clouds for rendering natural scenes are essential. 3D Simplex noise technology is a new kind of noise generation method which is improved by 3D Perlin noise. 3D Simplex noise technology was used to generate 3D noise gray-scale images. Through the noisy image sharpening and color conversion, the 3D Simplex noise images were converted to blue sky and white clouds images, and finally with time function of the GLSL shading language, the fluttering clouds were achieved. The experiment results show that the 3D Simplex noise is low computational complexity to generate realistic images of the cloud and the generated realistic images of the cloud are effective.
