flow()

Flow Slic3r::LayerRegion::flow	(	FlowRole	role,
		bool	bridge = false,
		double	width = -1
	)		const

Flow object which provides methods to predict material spacing.

Creates a new Flow object with the arguments and the variables of this LayerRegion.

infill_area_threshold()

double Slic3r::LayerRegion::infill_area_threshold

(

)

const

Gets the smallest fillable area.

Gets smallest area by squaring the Flow's scaled spacing.

layer() [1/2]

Layer* Slic3r::LayerRegion::layer ( )

layer() [2/2]

const Layer* Slic3r::LayerRegion::layer ( ) const

make_fill()

void Slic3r::LayerRegion::make_fill

(

)

Generate infills for a LayerRegion.

The LayerRegion at this point of time may contain surfaces of various types (internal/bridge/top/bottom/solid). The infills are generated on the groups of surfaces with a compatible type. Fills an array of ExtrusionPathCollection objects containing the infills generated now and the thin fills generated by generate_perimeters().

make_perimeters()

void Slic3r::LayerRegion::make_perimeters	(	const SurfaceCollection &	slices,
		SurfaceCollection *	fill_surfaces
	)

Generates and stores the perimeters and thin fills.

Creates a new PerimeterGenerator object Which will return the perimeters by its construction

merge_slices()

void Slic3r::LayerRegion::merge_slices

(

)

Merges this->slices.

Merges this->slices with union_ex, and then repopulates this->slices.surfaces.

prepare_fill_surfaces()

void Slic3r::LayerRegion::prepare_fill_surfaces

(

)

Preprocesses fill surfaces.

If no solid layers are requested, turns top/bottom surfaces to internal Turns too small internal regions into solid regions according to the user setting

process_external_surfaces()

void Slic3r::LayerRegion::process_external_surfaces

(

)

Processes external surfaces for bridges and top/bottom surfaces.

Processes bridges with holes which are internal features. Detects same-orientation bridges and merges them. Processes and groups top and bottom surfaces This function reads layer->slices and lower_layer->slices and writes this->bridged and this->fill_surfaces, so it's thread-safe.

region() [1/2]

PrintRegion* Slic3r::LayerRegion::region ( )

inline

region() [2/2]

const PrintRegion* Slic3r::LayerRegion::region ( ) const
