Public Member Functions
	Slice (AnatomicalPlane plane=AnatomicalPlane::Axial)
	Default constructor, optionally defining a standard plane.

	Slice (const Corners &corners, const vec3 &direction)
	Create a slice from its four corners and its direction.
vec3	corner (int which) const
	Return one of the corners of the slice.
int	axisClosest () const
	Returns the unit axis to which the normal of this slice is closest.
bool	intersect (const Slice &other, vec3 &point1, vec3 &point2, bool finite=false) const

Member Enumeration Documentation

AnatomicalPlane

enum class AnatomicalPlane

strong

Enumeration of standard anatomical planes for slice-based visualization.

Enumerator
Undefined	unspecified plane.
Axial	horizontal/transverse plane dividing the body into cranial and caudal portions.
Sagittal	lateral/longitudinal plane dividing the body into left and right.
Coronal	frontal/vertical plane dividing the body into posterior and anterior portions.

Corner

enum Corner

Readable names for defining the four corners of a slice.

Enumerator
BottomLeft	Corner at (-sx, -sy)
BottomRight	Corner at ( sx, -sy)
TopRight	Corner at ( sx, sy)
TopLeft	Corner at (-sx, sy)

Constructor & Destructor Documentation

Slice()

Slice ( const Corners & corners )

explicit

Create a slice from its four corners.

The direction is determined from the cross product of the x-axis (left-to-right) and the y-axis (top-to-bottom).

Member Function Documentation

corner()

vec3 corner

(

int

which

)

const

Return one of the corners of the slice.

Parameters

which

Index of the corner to return (cf. Slice::Corner enumeration)

intersect()

bool intersect	(	const Slice &	other,
		vec3 &	point1,
		vec3 &	point2,
		bool	finite = false ) const

Returns true if an intersection with another slice exists, providing the points then.

If the parameter finite is set to true, the method returns false in case the limited slice extent does not overlap. Output points are returned in all cases though.
