off_query - list element data

Usage

Usage: off_query [options] query [input_file]

Read a file in OFF format and list element data for specified elements.
Added elements of the query type are also added to the query list.
Added elements are referred to by xN, where N is the order the element
was added (starting with 0). Query is a list of letters, the first is the
query element type V, F, or E followed by the values to print
   V - Vertex:
       c - coordinates             d - distance from centre
       f - face index numbs        F - face angles
       a - solid angle             n - neighbours
       o - order                   g - vertex figure
       K - colour
   E - Edge:
       v - vertex index nums       d - distance from centre
       f - face index nums         D - direction
       a - diheral angle           l - length
       c - central angle           C - centroid
       K - colour
   F - Face:
       v - vertex index nums       d - distance from centre
       n - neighbours              A - area
       N - normal                  C - centroid
       a - angles                  l - lengths
       s - number of sides         p - max nonplanar distance
       P - perimeter               K - colour

Options
  -h,--help this help message (run 'off_util -H help' for general help)
  --version version information
  -c <cent> centre of shape in form 'X,Y,Z', 0 to use origin, C to use
            centroid (default 0)
  -I <idxs> list of elements by index number given as index ranges
            separated by commas, range can be one number or two
            numbers separated by a hyphen (default range numbers: 0 and
            largest index, default argument: any added elements else '-')
  -v <crds> add vertex, coordinates in form 'X,Y,Z'
  -f <vnos> add face, a list of vertex index numbers separated by commas
  -e <vnos> add edges, a list of vertex index numbers separated by commas
            and taken in pairs
  -k        keep orientation, don't try to orient the faces
  -E <type> edges for query, e - explicit edges, i - implicit edges
            a - explicit and implicit (default)
  -o <file> write output to file (default: write to standard output)
  -d <dgts> number of significant digits (default 17) or if negative
            then the number of digits after the decimal point

Examples

off_query -I - VF -d 6 cubo

off_query -I 5-10,50-60,100 El -d 6 geo_4_1

off_trans -s e icosahedron | off_query -e 0,11 El

off_trans -s e icosahedron | off_query -f 0,1,11 Fa

off_trans -s e icosahedron | off_query -v 1.0,0.0,0.0 -f 0,x0,11 Fa
