Method Detail

initCams

public void initCams(int nbCam)

Description copied from class: Glyph

Initialize projected coordinates. Called internally when glyph is created in order to create the initial set of projected coordinates w.r.t the number of cameras in the virtual space.

Specified by:

initCams in class Glyph

Parameters:

nbCam - current number of cameras in the virtual space

See Also:

Glyph.addCamera(int verifIndex), Glyph.removeCamera(int index)

addCamera

public void addCamera(int verifIndex)

Description copied from class: Glyph

Create new projected coordinates. Called internally to create new projected coordinates to use with the new camera.

Specified by:

addCamera in class Glyph

Parameters:

verifIndex - camera index, just to be sure that the number of projected coordinates is consistent with the number of cameras.

See Also:

Glyph.initCams(int nbCam), Glyph.removeCamera(int index)

removeCamera

public void removeCamera(int index)

Description copied from class: Glyph

Dispose of projected coordinates. If a camera is removed from the virtual space to which this glyphs belongs, the corresponding projected coordinates should be deleted. the array of projected coordinates should not be modified however, because other cameras' index remain the same. The corresponding index in the array should just be set to null.

Specified by:

removeCamera in class Glyph

Glyph.initCams(int nbCam), Glyph.addCamera(int verifIndex)

public boolean fillsView(double w,
                         double h,
                         int camIndex)

Description copied from class: Glyph

Find out if this glyph completely fills a view. (In which case it is not necessary to repaint objects below it in the drawing stack). If implemented, this method should be very efficient, as it is used by an optional top-down clipping algorithm. Otherwise it might cost more time than it can potentially save. Until now it has only been implemented for non-reorientable rectangles and was activated only for treemap-like representations in which a lot of rectangles can potentially overlap each other.
