void	enable_polyline_refinement (const double &tolerance=0.08)
	Enable refinement of polylines to create a better representation of curvilinear boundaries (e.g. in free-surface problems). See tutorial for interpretation of the optional argument which specifies the refinement tolerance. It defaults to 0.08 and the smaller the number the finer the surface representation. More...

void	set_polyline_refinement_tolerance (const double &tolerance)
	Set tolerance for refinement of polylines to create a better representation of curvilinear boundaries (e.g. in free-surface problems). See tutorial for interpretation of the refinement tolerance. (The smaller the number the finer the surface representation). If set to a negative value, we're switching off refinement – equivalent to calling disable_polyline_refinement() More...

double	polyline_refinement_tolerance ()
	Get tolerance for refinement of polylines to create a better representation of curvilinear boundaries (e.g. in free-surface problems). See tutorial for interpretation. If it's negative refinement is disabled. More...

void	disable_polyline_refinement ()
	Disable refinement of polylines. More...

void	enable_polyline_unrefinement (const double &tolerance=0.04)
	Enable unrefinement of polylines to avoid unnecessarily large numbers of elements on of curvilinear boundaries (e.g. in free-surface problems). See tutorial for interpretation of the optional argument which specifies the unrefinement tolerance. It defaults to 0.04 and the larger the number the more agressive we are when removing unnecessary vertices on gently curved polylines. More...

void	set_polyline_unrefinement_tolerance (const double &tolerance)
	Set tolerance for unrefinement of polylines to avoid unnecessarily large numbers of elements on of curvilinear boundaries (e.g. in free-surface problems). See tutorial for interpretation of the optional argument which specifies the unrefinement tolerance.
