Very long Mandelbrot zoom

ah, i see, although still horribly low resolution, are you sure those blobs are not because to few iterations ?  inside these blobs you would need more iterations to complete the image...

I'm not sure I understand, can't you use my java app?

I can use it, but there are bugs (it doesn't allow me to change the max iterations and coordinates, hangs often), and it lacks much functionality to be really useful. I think java also makes it slower than it could be by default, because it runs in a browser. Considering how fast it is already, this has much more potential than what we can do right now.

I had a look at them in the java application and I'm pretty sure it's not a lack of iterations. The max iterations is at 200000 while the green thing is just over 90000.

If you change the max iterations, then select 'refresh' from the menu bar it should work ok.
Do you have any reproduction steps to make it hang?

It hangs often when it finishes a render. This seems to happen mostly when I go close to the mandelbrot set (or a small mandelbrot set). The progress bar indicates that the render is done, but then the program hangs. With deep zooms, the program lags a lot but it still responds after waiting 10 seconds or so. The only way for me to go anywhere deep is to use the library.

At the moment it hangs so much that I can't even try your method to change the max iterations.

Did you try the low memory version? I suspect that the high memory version is exposing some stability problems in browsers. The high memory version seems to completely crash Chrome, but the low memory one seems to work ok. The two versions are exactly the same apart from the start up parameters.

I've made this for you

The blobs are caused by the points drifting too far away from the reference point, causing them to lose accuracy, which makes them indistinguishable from one another, and they come out the same colour.

right, there must have been some limit, dude, nice nice nice, this will improve fractal rendering very much!
thank you for sharing it with us, now i (or we?) just need to understand how to apply it to a rendering process, is your programm open source?
