Hi @ all,

i am at the moment implementing for debug-purposes the hugo elias algorithm under openframeworks. However, this hasn't much to do with the real question.



He is creating buffer1, buffer2

buffer1 = new int[width * height];
buffer2 = new int[width * height];

without initializing them later as follows:

tdlu = buffer1[i-1] + buffer1[i+1] + buffer1[i - width] + buffer1[i + width];
buffer2 = ( tdlu / 2 - buffer2);

buffer2 -= (buffer2 >> 5); //(int)(buffer2*damping);

if its not properly when i initialize buffer1,buffer2 with 0 or random values expect random numbers between the int limit

buffer2 = ofRandom(-2147483648, 2147483647);

It would be cool if someone knows this ;)

thank you very much
