Quote from: Matt on January 28, 2014, 06:41:32 amI prepared this one just now. Most of the documentation we have is in the Wiki: http://planetside.co.uk/wiki/index.php?title=Main_PageI'll transfer this information over to the Wiki.MattBrilliant...I think I finally get it...thanks Matt...
Quote from: Matt on January 28, 2014, 06:14:23 amBTW, the scale ratio between octaves (known as 'lacunarity') in the Power Fractal is 1.92, so to calculate the number of octaves I use log to the base 1.92, so it would be something like:log( leadinScale / smallestScale ) / log(1.92)Matt
Quote from: Matt on January 28, 2014, 06:04:00 amHi eps,The lead-in octaves have the same amplitude as the feature scale octave. While the "roughness" parameter controls the damping of octaves below the feature scale all the way down to the smallest scale, it does not affect the octaves above the feature scale.Matt
Quote from: Tangled-Universe on January 28, 2014, 11:20:59 amThanks for sharing this nice picture Matt, I immediately have some ideas and perhaps possible improvements or even solutions for cloud things I'm working on for many years.
QuoteCurious, if I calculate it manually I always end up with 1 octave less. How come, where's the extra octave coming from?
QuoteLacunarity is perhaps interesting to manipulate, are you considering unlocking it in the interface? Will the shader/code allow for it anyway?
