qhalf- halfspace intersection about a point. Qhull 2015.2 2016/01/18 input (stdin): [dim, 1, interior point], dim+1, n, coefficients+offset comments start with a non-numeric character options (qhalf.htm): Hn,n - specify coordinates of interior point Qt - triangulated output QJ - joggled input instead of merged facets Tv - verify result: structure, convexity, and redundancy . - concise list of all options - - one-line description of all options -V - version output options (subset): s - summary of results (default) Fp - intersection coordinates Fv - non-redundant halfspaces incident to each intersection Fx - non-redundant halfspaces o - OFF file format (dual convex hull) G - Geomview output (dual convex hull) m - Mathematica output (dual convex hull) QVn - print intersections for halfspace n, -n if not TO file - output results to file, may be enclosed in single quotes examples: rbox d | qconvex FQ n | qhalf s H0,0,0 Fp rbox c | qconvex FQ FV n | qhalf s i rbox c | qconvex FQ FV n | qhalf s o
