Plus

You'll need the most recent version of the ArtGraph software to reproduce 'Plus'. This is because it uses the new "autobase off" feature. With older versions you may get black spots where the landscape dips below the predicted lowest point. In equations that use the random function, predicting a low (but not too low) point is awkward and time consuming: autobase was the simple solution.

(abs(x)-sin(abs(x)))^rnd(7)+(abs(y)-sin(abs(y)))^rnd(7)=0

scanjump is 0.05

linearity is 16

colour data is 186 219 238 188 175 247 231 095 174 111 189 235 103 227 126

x-axis -11 to 11 : y-axis -10 to 10 

autobase off - set at 35831604
