Constructor & Destructor Documentation

Disc() [1/2]

ml::Disc::Disc

(

)

Constructor. Default state is center at (0,0,0), normal (1,0,0) and radius 0.

Member Function Documentation

fill() [1/2]

void ml::Disc::fill	(	const MedicalImageProperties &	pImg,
		SubImage &	destImg,
		double	fillVal ) const

Draw disc with value fillVal into subimage destImg.

The disc is transformed by transformation given by pImg. Only overlapping regions of extents of destImg and pImg are written.

fill() [2/2]

void ml::Disc::fill	(	const MedicalImageProperties &	pImg,
		VirtualVolume &	destImg,
		double	fillVal ) const

Draw disc with value fillVal into VirtualVolume destImg.

The disc is transformed by transformation given by pImg. Only overlapping regions of extents of destImg and pImg are written.

getBoundingBox() [1/2]

void ml::Disc::getBoundingBox	(	const Matrix4 &	transform,
		Vector3 &	boxMin,
		Vector3 &	boxMax ) const

Compute bounding box of disc in target coordinates; box is a homogeneous matrix specifying the transformation.

getBoundingBox() [2/2]

SubImageBox ml::Disc::getBoundingBox

(

const MedicalImageProperties &

pImg

)

const

Compute bounding box of disc in voxel coordinates.

pImg are MedicalImageProperties to specify a maximum extent of the filled region, the transformation matrix and voxel size.

getCenter()

const Vector3 & ml::Disc::getCenter ( ) const

inline

Get center.

Definition at line 57 of file mlDisc.h.

getNormal()

const Vector3 & ml::Disc::getNormal ( ) const

inline

Get normal.

Definition at line 60 of file mlDisc.h.

getPlane()

Plane ml::Disc::getPlane ( ) const

inline

Get Plane object in which disc is located.

Definition at line 74 of file mlDisc.h.

getRadius()

double ml::Disc::getRadius ( ) const

inline

Get radius.

Definition at line 63 of file mlDisc.h.

intersect()

bool ml::Disc::intersect ( const Line & l, Vector3 & cut ) const

inline

Intersects line l with disc plane, true if cut point exists, no radius check.

project()

bool ml::Disc::project ( const Vector3 & p, Vector3 & proj ) const

inline

Definition at line 47 of file mlDisc.h.

setNormal()

bool ml::Disc::setNormal

(

const Vector3 &

n

)

Set normal vector (performing normalization, (1,0,0) if zero).

Return true if normal vector is not zero

setRadius()

void ml::Disc::setRadius ( double r )

inline

Set radius.

Definition at line 54 of file mlDisc.h.

setValue()
