Class PjSurface

java.lang.Object

jv.object.PsObject

jv.project.PjProject

vgp.surface.common.PjSurface

All Implemented Interfaces:

java.io.Serializable, java.lang.Cloneable, PsTimeListenerIf, PsUpdateIf, PvPickListenerIf

public class PjSurface
extends PjProject

Parameterized surfaces given by Java functions, or interactively, by function expressions. If the functions of a surface are specified in calc_f method and, later, interactively edited, then the interactive expressions are further used. This is important for evaluation of higher order differentials since they are only approximated using finite differences in the later case.

Applet parameters "SurfaceName", "SurfaceParams" and "SurfaceColors" can be defined:

SurfaceName: project will load a surface with name "PgSurface_"+SurfaceName

SurfaceParams: Uppercase means show, lowercase means don't show, not defined means standard, i.e. vLEb.

    v:  vertices
    l:  edges (lines)
    e:  elements
    b:  boundary
 

SurfaceColors:

    w:  white
    r:  red
    g:  green
    b:  blue
    c:  cyan
    m:  magenta
    y:  yellow
    k:  black

Method Detail

init

public void init()

Description copied from class: PjProject

Initialize and reset project, stops the running animation if any. Does not reset any registered display nor geometry. They must be reset individually in each subclass.

Overrides:

init in class PjProject

start

public void start()

Description copied from class: PjProject

Method is invoked during loading of a project in JavaView.

If a project has an animation object, then the animation panel is shown when the project's this start() method is invoked during loading of the project. Use setAnimation(PsAnimation) to register an animation.

If auto fit is enabled then scenery is scaled to fit in each display.

Overrides:

start in class PjProject

See Also:

PvViewerIf.start(), PjProject.isEnabledAutoFit()

setSurfaceNames

public void setSurfaceNames(java.lang.String surfaces,
                            java.lang.String params,
                            java.lang.String colors)

Assign name of a single surface, or of several surface names separated by semi-colon.

loadSurfaces

public boolean loadSurfaces(java.lang.String surfaces,
                            java.lang.String params,
                            java.lang.String colors)

Assign name of a single surface, or of several surface names separated by semi-colon. The surface is immediately loaded.

pickInitial

public void pickInitial(PvPickEvent pos)

Pick events are used by some scenes to modify individual geometries of a scene. Currently this method uses the x,y and z component of the pick position to set surface parameters with same names if the parameters exist.

Specified by:

pickInitial in interface PvPickListenerIf

Overrides:

pickInitial in class PjProject

Parameters:

pos - Pick event issued by the display

See Also:

PvPickListenerIf

update

public boolean update(java.lang.Object event)

Update the class whenever a child has changed. Method is usually invoked from the children.

Specified by:

update in interface PsUpdateIf

Overrides:

update in class PsObject

Parameters:

event - carries a lot of information

Returns:

true if event has been handled, otherwise false

PsObject.setParent(PsUpdateIf), PsObject.getFather(), PsObject.addUpdateListener(PsUpdateIf)
