Slic3r::Layer::Layer	(	size_t	id,
		PrintObject *	object,
		coordf_t	height,
		coordf_t	print_z,
		coordf_t	slice_z
	)

protected

Constructor.

Initialises upper_layer, lower_layer to NULL Initialises slicing_errors to false

Slic3r::Layer::~Layer ( )

protectedvirtual

Destructor.

Removes references to self and clears regions.

Member Function Documentation

◆ add_region()

LayerRegion * Slic3r::Layer::add_region ( PrintRegion * print_region )

Adds a PrintRegion.

Creates a LayerRegion from a PrintRegion and adds it to this->regions.

◆ any_bottom_region_slice_contains()

template<class T >

template bool Slic3r::Layer::any_bottom_region_slice_contains< Polyline > ( const T & item ) const

Template which iterates over all of the LayerRegion for containing on the bottom the argument.

Uses LayerRegion->slices.any_bottom_contains(item)

◆ any_internal_region_slice_contains()

template<class T >

template bool Slic3r::Layer::any_internal_region_slice_contains< Polyline > ( const T & item ) const

Template which iterates over all of the LayerRegion for internally containing the argument.

Uses LayerRegion->slices.any_internal_contains(item)

◆ clear_regions()

void Slic3r::Layer::clear_regions ( )

protected

Deletes all regions.

Deletes all regions using this->delete_region()

◆ delete_region()

void Slic3r::Layer::delete_region ( int idx )

protected

Deletes a specific region.

Deletes an individual region.

◆ detect_surfaces_type()

void Slic3r::Layer::detect_surfaces_type ( )

Determines the type of surface (top/bottombridge/bottom/internal) each region is.

Analyzes slices of a region (SurfaceCollection slices). Each region slice (instance of Surface) is analyzed, whether it is supported or whether it is the top surface. Initially all slices are of type S_TYPE_INTERNAL. Slices are compared against the top / bottom slices and regions and classified to the following groups: S_TYPE_TOP - Part of a region, which is not covered by any upper layer. This surface will be filled with a top solid infill. S_TYPE_BOTTOMBRIDGE - Part of a region, which is not fully supported, but it hangs in the air, or it hangs losely on a support or a raft. S_TYPE_BOTTOM - Part of a region, which is not supported by the same region, but it is supported either by another region, or by a soluble interface layer. S_TYPE_INTERNAL - Part of a region, which is supported by the same region type. If a part of a region is of S_TYPE_BOTTOM and S_TYPE_TOP, the S_TYPE_BOTTOM wins.

◆ get_region() [1/2]

LayerRegion* Slic3r::Layer::get_region ( size_t idx )

inline

Gets a region at a specific id.

◆ get_region() [2/2]

const LayerRegion* Slic3r::Layer::get_region ( size_t idx ) const

inline

Gets a region at a specific id as const.

◆ id()

size_t Slic3r::Layer::id ( ) const

ID number.

Getter for this->_id.

◆ is_support()

virtual bool Slic3r::Layer::is_support ( ) const

inlinevirtual

polymorphic id

Reimplemented in Slic3r::SupportLayer.

◆ make_fills()

void Slic3r::Layer::make_fills ( )

Makes fills for all the LayerRegion.

Iterates over all of the LayerRegion and invokes LayerRegion->make_fill() Asserts that the fills created are not NULL

◆ make_perimeters()

void Slic3r::Layer::make_perimeters ( )

Creates the perimeters cummulatively for all layer regions sharing the same parameters influencing the perimeters.

The perimeter paths and the thin fills (ExtrusionEntityCollection) are assigned to the first compatible layer region. The resulting fill surface is split back among the originating regions.

inline

Getter for _object.

◆ object() [2/2]

const PrintObject* Slic3r::Layer::object ( ) const

inline

◆ process_external_surfaces()

void Slic3r::Layer::process_external_surfaces ( )

Returns the number of regions.

Getter for this->regions.size()

◆ set_id()

void Slic3r::Layer::set_id ( size_t id )
