This is a simple GTK+ program that lets you zoom in on the Mandelbrot set.
You will need gtkmm and either GNU C++ or Clang.
apt install libgtkmm-2.4-dev autoconf-archive
./autogen.sh
./configure
make check
sudo make install
If you want to compile with Clang :
./configure CC=clang CXX=clang++ CCAS=gcc
See man mandy for documentation.
You can select at runtime the arithmetic type used to compute the images.
double gives you about 53 bits of precision.
It is usually directly supported by CPU hardware, so very fast.
simd is the same data type as double but uses vector instructions
if available, giving a 2x or 4x acceleration depending on platform.
long double is very platform dependent. On x86 it gives you 64 bits of precision. On Arm it is more precise but also quite slow, due to lack of hardware support.
fixed64 gives you 56 bits of precision after the point. The x86 implementation
is well optimized.
fixed128 gives you 96 bits of precision after the point. The x86 implementation
is well optimized.
fixed256 gives you 192 bits of precision after the point. The x86 and Arm
implementations are somewhat optimized.
