rcBuildContours()

bool rcBuildContours	(	rcContext *	ctx,
		rcCompactHeightfield &	chf,
		const rcReal	maxError,
		const int	maxEdgeLen,
		rcContourSet &	cset,
		const int	buildFlags
	)

The raw contours will match the region outlines exactly. The maxError and maxEdgeLen parameters control how closely the simplified contours will match the raw contours.

Simplified contours are generated such that the vertices for portals between areas match up. (They are considered mandatory vertices.)

Setting maxEdgeLength to zero will disable the edge length feature.

See the rcConfig documentation for more information on the configuration parameters.
