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? -jim [1] http://hackage.haskell.org/package/GlomeVec [2] http://hackage.haskell.org/package/IcoGrid [3] http://www.haskell.org/haskellwiki/IcoGrid
