Turing Pattern renders classic `papillary lines' Turing pattern and a few
more patterns, some are metastable, some are completely unstable I simply
liked when I saw them.


Installation
------------

Requirements: Gimp 2.2.

Untar the tar file (well I guess you've got that far already), then in the
directory thus created type

      make install

to install the plug-in to the system-wide plug-in directory, or

      make install-user

to install it to your user plug-in directory.  You can uninstall it later by
`make uninstall' or `make uninstall-user', respectively. When something goes
wrong, try modify the Makefile or, if you are really desperate, the source.


Usage
-----

This plug-in installs itself in the Filters/Render/Pattern menu as
`Turing Pattern'.

Parameter description:

* Feature size

  Characteristic wavelength for Papillary lines mode (not available for
  other modes).

* Pattern type

  All patterns represent snapshots of numeric solution of a pair of coupled
  nonlinear differential equations

    ∂v
    --  +  μ  Δv  =  f(u, v)
    ∂t      v

    ∂w
    --  +  μ  Δw  =  f(u, v)
    ∂t      w

  where the function f and the parameters generally differ between modes and
  can be looked up in the source code.  Some snapshots represent
  a [meta]stable solution, others may be just snapshots.

  Papillary lines is the pattern I was originally trying to generate, the
  rest are simply patterns I noticed and liked when I was exploring the space
  of parameters of the differential equations, there is nothing special about
  them.
