fractalshades's Issues
Stability issue for large images
It appears PR #112 (needed for compatibility with WINDOWS) has also introduced instability and crash when rendering large image esp. with supersampling. From first investigations, the solution seems to be: close all numpy memaps right after access, even in "r+" mode.
As a data point, rendering a 3200 x 3200 image with 5x5 supersampling crashes on my machine.
Unable to run in Mac M1
So, I am having an issue running the project on M1 Mac.
The error is as follows:
#warning "Using deprecated NumPy API, disable it with " \
^
src/fractalshades/mpmath_utils/FP_loop.c:790:10: fatal error: 'gmp.h' file not found
#include "gmp.h"
^~~~~~~
1 warning and 1 error generated.
error: command '/usr/bin/clang' failed with exit code 1
[end of output]
note: This error originates from a subprocess, and is likely not a problem with pip.
ERROR: Failed building wheel for fractalshades
Failed to build fractalshades
ERROR: Could not build wheels for fractalshades, which is required to install pyproject.toml-based projects
I tried to look into the issue and found a similar solution for missing gmp.h here at OpenZeppelin/nile#22
However, the error still persists. I tried all the solutions mentioned, but am having issues running them.
Allow rendering larger image
A PIL.Image.DecompressionBombError is raised when the image size exceed a limit (as a data point, this is the case for a 40000 x 40000 image). Allow rendering images of larger size, or implement anti-aliasing for large images.
Investigate failing test_db on OS Windows
These failures might be a red herring, to be investigated.

projection.Expmap
Hi,
Tx for great program
Can you write more about :
- "rotates_df : If True, the derivative will be scaled but also rotated according to the mapping."
- screen pixels are defined in [0.5, 0.5]x[-0.5, 0.5]
- the xy_ratio will be udjusted ...
- h_{moy}
TIA
Newer version of python/numpy/gmpy breaks the software utterly
Pls update dependency asap and fix compatibility issue.
gmpy2.15 built release only supports python version <3.12 atm
numba version >0.57 deprecated generated_jit used by fractalshades and will output the following warnings:
ImportError: cannot import name 'generated_jit' from 'numba'
Smooth coloring with high iterations
When you zoom into locations that contain a lot of iterations (> 10 millions), the coloring becomes inaccurate and no longer smooth.
This banding is a limitation due to float32 precision, which is the precision used internally during post processing
No result + no reaction of computer
I have installed Fractalshades 1.0.1 on my computer.
I have exported a Python script from the Fractalshades GUI (see attachment, Stopped.py) and disabled the Newton calculation, because the center of the fractal is already known. The reference orbit has a length of 500 million. After approx. 3h of computing time, the program closes unexpectedly without any result. See attachment, Stopped.png. After reopening the program, it said that the orbit was calculated and the calculation of the image would begin. But then my computer froze. After 3-5 minutes the program stopped, again.
I believe this is unintentional and would appreciate further investigation.
PS: The logfile’s name is misspelled, it has a typo: It says “factalshades” instead of “fractalshades”.
Request: Magnet Mandelbrot
Hi! I've long struggled to add the Magnet Mandelbrot in Kalles Fraktaler, so I figured the next best thing to do is to ask if it is possible to have both Types I and II Magnet Mandelbrot in Fractalshades?
These fractals deserve more love and exploration
Getting greyscale image for rendering in blender?
I see mention of using an output file as a DEM to use as input to blender, but there are no examples showing how to do this and
I can't see how to use Disp_layer to get a 32bit image file to use in blender.
I did try loading the stop_iter.arr file, but could not see how to map the long array to a 2d image
