Member Function Documentation

cut()

template<Axis A>

void Slic3r::TriangleMeshSlicer< A >::cut	(	float	z,
		TriangleMesh *	upper,
		TriangleMesh *	lower
	)		const

Splits the current mesh into two parts.

Parameters

[in]	z	Coordinate plane to cut along.
[out]	upper	TriangleMesh object to add the mesh > z. NULL suppresses saving this.
[out]	lower	TriangleMesh object to save the mesh < z. NULL suppresses saving this.

slice() [1/3]

template<Axis A>

void Slic3r::TriangleMeshSlicer< A >::slice	(	const std::vector< float > &	z,
		std::vector< Polygons > *	layers
	)		const

This method gets called with a list of unscaled Z coordinates and outputs a vector pointer having the same number of items as the original list. Each item is a vector of polygons created by slicing our mesh at the given heights.

This method should basically combine the behavior of the existing Perl methods defined in lib/Slic3r/TriangleMesh.pm:

• analyze(): this creates the 'facets_edges' and the 'edges_facets' tables (we don't need the 'edges' table)
• slice_facet(): this has to be done for each facet. It generates intersection lines with each plane identified by the Z list. The get_layer_range() binary search used to identify the Z range of the facet is already ported to C++ (see Object.xsp)

• make_loops(): this has to be done for each layer. It creates polygons from the lines generated by the previous step.

  At the end, we free the tables generated by analyze() as we don't need them anymore.

  NOTE: this method accepts a vector of floats because the mesh coordinate type is float.

slice() [2/3]

slice_facet()

template<Axis A>

void Slic3r::TriangleMeshSlicer< A >::slice_facet	(	float	slice_z,
		const stl_facet &	facet,
		const int &	facet_idx,
		const float &	min_z,
		const float &	max_z,
		std::vector< IntersectionLine > *	lines,
		boost::mutex *	lines_mutex = NULL
	)		const
