The gruff package
Mandelbrot Set fractal explorer using the ruff library.
Requires GTK, OpenGL, and GLSL fragment shader support; lots of RAM and multiple CPU cores recommended. If you want to explore very deep zooms, you'll need hmpfr which currently requires GHC to be compiled with integer-simple instead of the default integer-gmp. To install without MPFR support, use cabal install gruff -f-mpfr.
This version is a bugfix release. Changes since gruff-0.2:
Supersampling bugs are fixed (no more undocumented quantization leading to inconsistent appearance at different zoom levels).
Race condition bugs in cache management are fixed (no more incompletely rendered images).
Internal changes/refactoring to make future additions easier.
Features in this version include:
Interactive fractal browser display (left click to zoom in, right click to zoom out, middle-click to center).
Session persistance (stored in ~/.gruff/state.gruff - states can also be loaded from and saved to other files).
Tile cache (by default in ~/.gruff/cache - symlink it somewhere with a few GB of space if you plan on exploring a lot).
High-level feature finding using angled internal addresses (enter an address, for example 1 2 3 1/3 10, and hit return, then click the adjacent Go button).
Feature finding using period location (navigate to approximate location of the desired feature, click the Scan button).
Angled internal address calculation using reverse ray trace (navigate to approximate feature location, click the Scan+ button).
Uses MPFR where available for higher precision, allowing deeper zooms and locating high period nucleii.
Limited amount of customizable colouring (colours for interior, border, and exterior points).
Supersampling for more detailed images (useful range is 1 to 16).
Future features might include image saving, external ray and feature information overlays, more feature finding and identification algorithms, scripting support for rendering animations, ...
