All Implemented Interfaces:

AbstractUpdateManager.Window

public class Screen

extends java.lang.Object

implements AbstractUpdateManager.Window

An aggregate which defines a user-visible window and its contents. The View+Controller part of MVC.

Field Summary

Binder	binder The input handler (controller).
static boolean	dbg
protected float	latestFract
protected float	latestLod
protected VobScene	next
protected VobScene	prev
static java.lang.String	rcsid
Shower	shower The view.
GraphicsAPI.Window	window The window system -level window.

Constructor Summary

Screen(GraphicsAPI.Window window, Binder binder, Shower shower)

Method Summary

boolean	animUseful()
void	changeStartState(float fract) After this renderAnim(0, ...) would do the same as renderAnim(fract, ...) did before the call, if the end state wasn't destroyed (which it is).
void	endAnimation() Same as changeStartState(1), except that the end state doesn't exist afterwards.
boolean	generateEndState(int millis, float lod) Creates an end state, and returns true iff the time given for generation was sufficient for the given level of detail.
VobScene	getVobSceneForEvents()
boolean	hasEndState() Whether the endstate has been generated.
void	printScreen()
void	renderAnim(float fract, float lod, boolean showFinal) Render state between start and end (interpolation), with the specified level of detail.
void	renderStill(float lod) Renders and display current view state on screen

Method Detail

printScreen

public void printScreen()

hasEndState

public boolean hasEndState()

Description copied from interface: AbstractUpdateManager.Window

Whether the endstate has been generated.

Specified by:

hasEndState in interface AbstractUpdateManager.Window

animUseful

public boolean animUseful()

Specified by:

animUseful in interface AbstractUpdateManager.Window

changeStartState

public void changeStartState(float fract)

Description copied from interface: AbstractUpdateManager.Window

After this renderAnim(0, ...) would do the same as renderAnim(fract, ...) did before the call, if the end state wasn't destroyed (which it is). Used when the end state changes during animation, so that the animation continues from the state it reached, instead of jumping. If the end state doesn't exist, may crash.

Specified by:

changeStartState in interface AbstractUpdateManager.Window

endAnimation

public void endAnimation()

Description copied from interface: AbstractUpdateManager.Window

Same as changeStartState(1), except that the end state doesn't exist afterwards. If there is no end state, must be a no-op.

Specified by:

endAnimation in interface AbstractUpdateManager.Window

generateEndState

public boolean generateEndState(int millis,
                                float lod)

Description copied from interface: AbstractUpdateManager.Window

Creates an end state, and returns true iff the time given for generation was sufficient for the given level of detail. If false is returned, lower level of detail would have produced a better result.

Specified by:

generateEndState in interface AbstractUpdateManager.Window

renderStill

public void renderStill(float lod)

Renders and display current view state on screen

Specified by:

renderStill in interface AbstractUpdateManager.Window

renderAnim

public void renderAnim(float fract,
                       float lod,
                       boolean showFinal)

Description copied from interface: AbstractUpdateManager.Window

Render state between start and end (interpolation), with the specified level of detail. fract is in [0, 1], and so is lod. 0.5 should be assumed to be the default lod. If the end state doesn't exist, may crash.

Specified by:

renderAnim in interface AbstractUpdateManager.Window

Parameters:

showFinal - Whether to show (unanimated) the parts of the final view that are not animated. This can be used to make the effect of going slightly too far - coming back faster, not making the user wait for the very end of the animation to see everything.

getVobSceneForEvents

public VobScene getVobSceneForEvents()
