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.

Overrides:

initCams in class VCircle

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.

Overrides:

addCamera in class VCircle

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)

orientTo

public void orientTo(double angle)

Set the glyph's absolute orientation.

Overrides:

orientTo in class VCircle

Parameters:

angle - in [0:2Pi[

fillsView

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.

Overrides:

fillsView in class VCircle

coordInside

public boolean coordInside(int jpx,
                           int jpy,

                           double cvx,
                           double cvy)

Description copied from class: Glyph

Detect whether the given point is inside this glyph or not.

Overrides:

Parameters:

jpx - provide projected JPanel coordinates of the associated view, not virtual space coordinates

jpy - provide projected JPanel coordinates of the associated view, not virtual space coordinates

c - camera through which the glyph is observed (only a few types of Glyph actually require this information: SICircle, SIRectangle, VText)

cvx - virtual space coordinates

cvy - virtual space coordinates
