I've been doing some work for the past few weeks on a generative/generic 2D geometry library (leaving open the possibility for 3D in the future). The idea is for all the algorithms to be generative taking coordinate, point, segment, polyline/gon types as template parameters (or deducing where presented as nested typedefs) and specialized traits types for accessing type traits and methods ( things like access_traits<point_type>::get_x( point ) .).
So far the library has allowed me to work with the same algorithms in native floating type and exact types like gmp's mpq_class. It's just a first rough draft of ideas, and I would really like some input from the community to see if I'm on the right track for something that boost would be interested in having.
This all looks interesting stuff of course. And the use of templates is adventurous. I trust it does not mean that the need for both compile and runtime speed won't lead some to reject the library outright. I presume one could also use it with other arbitrary (but inexact) precision libraries? Past discussions on geometry have not produced a consensus on design/spec :-(( So you may prefer to ignore that and simply present your version. There is the little matter of some documentation ;-) Paul PS I see you have neatly 're-solved' the floating point comparison problems, and present them in a more generally useful form that in Boost.Test. I find the function names a step too long, but I feel that they would be most useful as a independent module. --- Paul A Bristow Prizet Farmhouse, Kendal, Cumbria UK LA8 8AB +44 1539561830 & SMS, Mobile +44 7714 330204 & SMS pbristow@hetp.u-net.com
