28 : : * \brief Place holder for decimation options
29 : :
30 : : * Options for decimation can be passed with the test driver.
31 : : *
32 : : * - -o \<file\> Output final model to given file, using moab output conventions
33 : : * - -s \<count\> Set the target number of faces.
34 : : * - -i \<timings\> Intervals for timing reports.
35 : : * - -e \<thresh\> Set the maximum error tolerance.
36 : : * - -t \<t\> Set pair selection tolerance.
37 : : * - -Q[pv] Select what constraint quadrics to use [default=p].
38 : : * - -On Optimal placement policy.
39 : : * 0=endpoints, 1=endormid, 2=line, 3=optimal [default]
40 : : * - -B \<weight\> Use boundary preservation planes with given weight.
41 : : * - -b preserve boundary (do not use with -B option)
42 : : * - -m Preserve mesh quality.
43 : : * - -a Enable area weighting.
44 : : * - -p Height fields positivity. Used for height fields, assume
45 : : * - -k maintain Euler characteristic of the model (topology unchanged)
46 : : * triangles are originally positively oriented.
47 : : * - -d Use delayed deletion, as opposed to merging
48 : : * - -c keep costs in a (sparse!!!!) tag
49 : : * - -l log file
50 : : * - -L output level in the log file
