Hi, Using boost geometry points, I have an algorithm using a 3D multi polygon. At the beginning the z axis is set at 0 and I use algo like correct and within. It forces me to copy all my multipolygons to the 2d space, do what I need and then reconvert back in 3D. I could as well start with in 2d,do what I need and later convert to 3d but still, it is a copy and a performance and memory loss. Could we have a mean to avoid that? By accepting 3d components in 2d functions, disabling one axis via a strategy? But preventing 2d components from accessing 3d functions because one slot of memory is missing. Thanks! -- _______________________________________________ Boost-users mailing list [email protected] https://lists.boost.org/mailman/listinfo.cgi/boost-users
