The source code runs in 2-d, 3-d, 4-d, and 10 higher dimensions. Qhull implements the Quickhull algorithm 11 for computing the convex hull. It handles roundoff errors 12 from floating point arithmetic. It computes volumes, surface 13 areas, and approximations to the convex hull. 14 15 http://www.qhull.org 16 17comment "qhull needs a toolchain w/ C++, gcc >= 4.4" 18 depends on !BR2_INSTALL_LIBSTDCPP || \ 19 !BR2_TOOLCHAIN_GCC_AT_LEAST_4_4 20
