Constructor & Destructor Documentation

◆ WBresenhamDBL()

WBresenhamDBL::WBresenhamDBL	(	std::shared_ptr< WGridRegular3D >	grid,
		bool	antialiased = `true`
	)

Initializes new raster algo.

Parameters

grid	The grid which defines the voxels which should be marked.
antialiased	If true then all voxels of a line are supported with anti-aliasing voxels around

Definition at line 33 of file WBresenhamDBL.cpp.

◆ ~WBresenhamDBL()

WBresenhamDBL::~WBresenhamDBL ( )

virtual

Finishes this raster algo.

Definition at line 38 of file WBresenhamDBL.cpp.

Member Function Documentation

◆ rasterSegment()

void WBresenhamDBL::rasterSegment	(	const WPosition &	start,
		const WPosition &	stop
	)

protectedvirtual

Scans a line segment for voxels which are hit.

Warning: Not every voxel which is hit by the segment will be marked but at least so many voxels so that the segment is represented by those voxels.

Note: This algorithm may be slow since using double operations.

Parameters

start	Start point of the line segment
stop	End point of the line segment

Reimplemented from WBresenham.

Definition at line 42 of file WBresenhamDBL.cpp.
