[Haskell-cafe] ANN: GlomeVec, IcoGrid

[Jim Snow]

I just uploaded two packages to hackage.

The first package [1] is the vector library used by my haskell 
ray-tracer, Glome, which has been neglected of late.  It's one of the 
first things I ever wrote in Haskell, so some of the code looks a little 
strange to me now, but it works pretty well for a wide variety of 
computational geometry tasks.  I also included a perlin noise 
implementation.

I released GlomeVec so that I would have a reasonable vector library to 
work off of for my other project, which is the IcoGrid library [2].  
IcoGrid (Icosahedron Grid) is a library for dealing with grids of 
hexagons and pentagons wrapped around a sphere.  Individual grid cells 
are identified by an integer, and the library can find all the neighbors 
of a given cell, it can find all the places where three cells intersect 
at a point, and it can also tell you where in 3-D space the center of 
the cell is.  (The cells are positioned on the surface of a sphere with 
unit 1.)  The one very useful function I haven't implemented yet is, 
given an arbitrary point, find the cell that the point "belongs" in.

I posted a screenshot on the Haskell wiki [3] showing an OpenGL 
application I wrote that uses IcoGrid.  My initial goal was to write 
some sort of simple environmental simulator that can eventually be made 
into a game.  The grid turned out to be a pretty big project by itself, 
so I turned it into a stand-alone library.

Both libraries have haddock docs, but they aren't showing up on 
hackage.  Is there a trick to tell hackage it needs to generate docs, or 
do I just need to wait for a cron job to run?
