int	face_target
	decimation stops when number of triangle is less than face_target; default 0
double	error_tolerance
	decimation can stop if the error is bigger than the given tolerance; default: HUGE (very large, so it is not stopping because of this)
int	will_use_plane_constraint
	will use plane constraint; default 1 (true)
int	will_use_vertex_constraint
	will use vertex constraint; default : 0 (false)
int	will_preserve_boundaries
	to preserve boundary edges; default 0 (false)
int	will_preserve_mesh_quality
	cost of creating inverted elements is artificially increased, so it should not happen; default: false
int	will_constrain_boundaries
	triggered by -B option; it will add an additional cost when boundary edges are collapsed used in conjunction with the boundary constraint weight: default false

	see the will_constrain_boundaries option
int	will_weight_by_area
	used if areas are planar ; default 0 (no)

Detailed Description

Place holder for decimation options.

Options for decimation can be passed with the test driver.

-o <file> Output final model to given file, using moab output conventions
-s <count> Set the target number of faces.
-i <timings> Intervals for timing reports.
-e <thresh> Set the maximum error tolerance.
-t <t> Set pair selection tolerance.
-Q[pv] Select what constraint quadrics to use [default=p].
-On Optimal placement policy. 0=endpoints, 1=endormid, 2=line, 3=optimal [default]
-B <weight> Use boundary preservation planes with given weight.
-b preserve boundary (do not use with -B option)
-m Preserve mesh quality.
-a Enable area weighting.
-p Height fields positivity. Used for height fields, assume
-k maintain Euler characteristic of the model (topology unchanged) triangles are originally positively oriented.
-d Use delayed deletion, as opposed to merging
-c keep costs in a (sparse!!!!) tag
-l log file
-L output level in the log file
