\"\"<\/p>\n

Converted Diamond Square Algorithm<\/a> \/ random midpoint displacement fractal from Processing (original by “Justin Seyster”) to Unity C#.
\n*See also related forum topic<\/a>.<\/p>\n

Release#1:<\/strong>
\n– Color32 array with SetPixels32() (instead of plotting each pixel at a time..)
\n– Replaced “\/2” with “*0.5f” (supposed to be bit better??)<\/p>\n

Ideas:<\/strong>
\n– Try to make some terrain height maps? Or just directly displace vertices from the function..?
\n– Does it work in 3D?
\n– Use it for drawing clouds? Minecraft map?
\n– What if you adjust parameters each frame, how it looks animated?
\n– Use as a shader? Someone has made one here<\/a>, who would convert to unity..?
\n– Mix colors with previous layer..?
\n– LookUpTables?<\/p>\n

Webplayer:<\/strong>
\nnothing to see..it just generates a texture as in screenshot..<\/p>\n

Image#3<\/strong>: deep profiler report (should try to put the colors in array..instead of using single setpixels..also could try using ints? and replace divisions with multipliers?)<\/p>\n

Small update: using array & setpixels<\/strong>, bit faster..<\/p>\n
