MaxScript——Point3的三维噪音函数

例子程序：

b_width = 320 b_height = 320 size = 10. z = 0. phase = 0.5 frequency = 10. fract_interval = 0.5 lacunarity = 2 octaves = 5 whichfunc = 2 b = bitmap b_width b_height for h = 0 to (b_height-1) do ( h_norm = (h as float/(b_height-1))*size row = for w=0 to (b_width-1) collect ( w_norm = (w as float/(b_width-1)) *size noise_val = case whichfunc of ( 1: noise3 [w_norm,h_norm,z] 2: noise4 [w_norm,h_norm,z] phase 3: turbulence [w_norm,h_norm,z] frequency 4: fractalNoise [w_norm,h_norm,z] fract_interval lacunarity octaves ) noise_val = 0.5 * (1.+noise_val) white*noise_val ) setpixels b [0,h] row ) display b

运行效果：
