Detailed Description

class to modify the position and scale to construct better illustration mode.

Todo:: add a constructor to automatically define the shift and the scale according a given associated SCell.

Examples: io/boards/dgtalBoard3D-2-ks.cpp, and io/viewers/viewer3D-4bis-illustrationMode.cpp.

Constructor & Destructor Documentation

◆ TransformedPrism() [1/2]

DGtal::TransformedPrism::TransformedPrism	(	const DGtal::Z3i::SCell &	aSurfel,
		double	aShift,
		double	aSizeFactor = `1.0`
	)

inline

Constructor.

Parameters

aSurfel	a DGtal::Z3i::SCell ( KhalimskySpaceND< 3, Integer > SCell ) .
aShift	the shift distance (positive or negative).
aSizeFactor	use to change the Prism size (1.0 initial size).

◆ TransformedPrism() [2/2]

DGtal::TransformedPrism::TransformedPrism	(	const DGtal::Z3i::SCell &	aSurfel,
		const DGtal::Z3i::SCell &	aVoxel,
		double	aShift = `0.05`,
		double	aSizeFactor = `0.75`
	)

inline

Constructor.

Parameters

aSurfel	a DGtal::Z3i::SCell ( KhalimskySpaceND< 3, Integer > SCell ) .
aVoxel	a DGtal::Z3i::SCell represent the voxel for which the surfel is associated. It permits to determine automatically the shift parameter (the surfel is automatically shifted towards this voxel).
aShift	the shift distance (positive or negative (default 0.05)).
aSizeFactor	use to change the Prism size (default 0.75).
