[ REQ 5165]: qhull problem
Hello, I have a problem with the qhull algorithm. Even for extremely small examples in dimension 2, and with parameters which remove the problems with collinear points, it produces an errormessage. A typical run: rbox 5 D2 | qhull C-0 Qcm -f qhull internal error (matchnewfacets): 3 neighbors did not match up hash 0 f4 v4 v0 neighbors: 2 -1 hash 1 f5 v4 v1 neighbors: 3 -2 While executing: rbox 5 D2 | qhull C-0 Qcm -f Last point added to hull was p4. At error exit: Convex hull of 5 points in 2-d: Number of vertices: 4 Number of facets: 4 Statistics: Number of points processed: 4 Number of hyperplanes created: 6 Number of distance tests for qhull: 10 Number of merged facets: 0 Number of distance tests for merging: 17 CPU seconds to compute hull (after input): 0 precision problems 1 flipped facets Do you have any idea what I do wrong? Thanks in advance, Andreas Fabri
