Do you ever use scaled long double?
Not yet, it is just a placeholder in the
Scale bits combo box. It is not needed at the zoom levels currently available in MM.
And how do you go beyond long double, do you use your version of "fixedfloat"?
Yes, I call it ASFloat (arbitrary scale float). It consists of a double as the mantissa and an int as the exponent, just like your fixedfloat type. Neither that is needed at modest zoom levels, but it still can be selected manually. (You also have to turn off
Use lower scale data types.)
800 million iterations, do you store on files?
No, the reference orbit is stored in RAM. The key is to only store the part needed after applying SA. For example if the iteration limit is set to 200M and 175M iterations can be skipped by SA, only the 25M remaining values have to be stored. That requires 25M * 8 bytes (for doubles) * 3 (re, im, abs parts) = 600 MB of RAM.
I have plugged in a mouse in my laptop because I finally wanted to implement the "standard" zooming defined by Fractal Extreme.
However I find it hard let the program break the animation and render to continue zooming before previous render is complete, without never crash.
I tried your program and it crashed and now it is in a state where it, after restart, crash as soon as I try to zoom further.
See the attached logs
Thanks. Could you also attach the last location you successfully rendered?
