Detailed Description

Utility class for functions that may be helpful when manipulating 3D volumes.

Member Function Documentation

static void com.fovia.hdrc.utils.hdrc3DHelpers.clipLineToPlane ( VECTOR3D  line[], PLANEEQF  plane  )

static

Clips the line to the plane. If the line is completely on the back side of the plane, the function will set the value of line[0] and line[1] to null.

Parameters

line	Array of length 2 that contains the two points for the line segment.
plane	The plane to clip to.

static VECTOR3D [] com.fovia.hdrc.utils.hdrc3DHelpers.clipLineToRectangle ( VECTOR3D  line[], VECTOR3D  rect[]  )

static

While it takes inand returns 3D vectors, this is a purely 2D function. Only X and Y are considered in calculations. null is returned if the line does not intersect with the rectangle. Note that this function will only work with axis-aligned rectangles. If you're rect isn't axis aligned, either write a new function or make it axis aligned via rotation.

Parameters

line	Two points on the line in question.
rect	Two points that define a rectangle. The ordering of the points should be top-left then bottom-right.

Returns

VECTOR3D[]

static boolean com.fovia.hdrc.utils.hdrc3DHelpers.cutPlaneAffectsVolume ( PLANEEQF  plane, VECTOR3D  vbp[], double  fudgeFactor  )

static

Cut plane use has a performance penalty if none of the volume is clipped. Use this function to verify that a cut plane is actually doing something.

Parameters

plane	The plane to test
vbp	Volume box points for the volume. See getVolumeBoxPoints().
fudgeFactor	Tolerance for determining if the cut plane is outside the volume. Greater values let cut planes closer to the volume be ignored

static VECTOR3D com.fovia.hdrc.utils.hdrc3DHelpers.getVolumeOffset ( VECTOR3D  firstSliceLoc, VECTOR3D  lastSliceLoc, VOLUME_DATA_PARAMS  vdp  )

static

See overload of this function getVolumeOffset(boolean,VECTOR3D,VECTOR3D,VOLUME_DATA_PARAMS). This version calls that version direction with bCenterOfSliceIsSliceLocation set to true.

Parameters

firstSliceLoc
lastSliceLoc
vdp

Returns

static VECTOR3D com.fovia.hdrc.utils.hdrc3DHelpers.getVolumeOffset ( boolean  bCenterOfSliceIsSliceLocation, VECTOR3D  firstSliceLoc, VECTOR3D  lastSliceLoc, VOLUME_DATA_PARAMS  vdp  )

static

Returns the offset of the volume center from the origin in the patient system of coordinates. Since all Fovia renderings set the center of the volume to be 0,0,0, adding this value to any point in Fovia's coordinates will return the coordinate as it should be in the DICOM spec. Subtracting this value from the point will reverse the action.

Parameters

bCenterOfSliceIsSliceLocation	If true, the slice location indicates the center of the slice. If false, the upper-left of the image is the location (DICOM standard).
firstSliceLoc	DICOM Image Location tag for the first slice in the volume
lastSliceLoc	DICOM Image Location tag for the last slice in the volume
vdp

Parameters

pt1	First point on the line
pt2	Second point on the line
