WebNote that since all the noise is calculated in the fragment shader, we are fill rate limited, so it will be slower at higher resolutions, or when the camera is closer to the planet. Take care to reduce overdraw. Let's change our n variable to use 6 octaves of fractal noise with frequency 0.1 and persistence 0.8: WebBasically he has a parameter on his noise function that blends between billow and ridge noise (-1 for billow, 0 for base noise, 1 for ridge). Then you use a separate layer of noise to control that tuning parameter. Depending on how you generate the outer noise you can control how quickly, often and extremely your lower noise layer warps between ...
