SEGMENTS

typedef std::vector< POLYSEGMENT > SEGMENTS

Definition at line 61 of file polygon_2d.h.

SEGMENTS_WIDTH_NORMALS

typedef std::vector< SEGMENT_WITH_NORMALS > SEGMENTS_WIDTH_NORMALS

List used to test ray2d intersections.

It will be a subset of an original polygon. The normals will be passed already interpolated.

ConvertPolygonToBlocks()

void ConvertPolygonToBlocks	(	const SHAPE_POLY_SET &	aMainPath,
		CONTAINER_2D_BASE &	aDstContainer,
		float	aBiuTo3dUnitsScale,
		float	aDivFactor,
		const BOARD_ITEM &	aBoardItem,
		int	aPolyIndex
	)

Use a polygon in the format of the ClipperLib::Path and process it and create multiple 2d objects (POLYGON_2D and DUMMY_BLOCK_2D) that can be used to represent this polygon area.

Parameters

aMainPath	the polygon are that was converted from the pcb board
aDstContainer	the destination container to put the created sub blocks
aBiuTo3dUnitsScale	the rendering target 3d scale
aDivFactor	a division factor (in 3Dunits) to divide the polygon plane, 0.0f will use the internal polygon segm statistics
