Yes, stochastic antialiasing (with Thresold = 0) work do the trick !!

But rendering time has increased considerably :

Method 1, Threshold 0.300, Depth 3, Jitter 1.00, Gamma 2.50 :
*1 minutes 51 seconds*

Method 3, Threshold 0.000, Depth 3, Jitter 1.00, Gamma 2.50 :
*48 minutes 19 seconds*

That is twenty-six times longer. As long as the image is good ;)
I update my web page.




@Bald Eagle : yes, Inigo Quilez web site is the site is really very
interesting but I have some trouble understanding a lot of things.



Thanks.
