Class Avatar

java.lang.Object

eu.svjatoslav.sixth.e3d.gui.Avatar

All Implemented Interfaces:

ViewRenderListener

public class Avatar
extends Object
implements ViewRenderListener

The avatar is a user-controlled object in the 3D world. It is a point in space that can be moved around by the user. It has orientation in space, and it can also be rotated around.

Method Details

beforeRender

public boolean beforeRender(ViewPanel viewPanel,
 int millisecondsSinceLastFrame)

Description copied from interface: ViewRenderListener

Notifies that it is about time (to keep constant framerate) to render next frame and allows listener to do any related processing that it needs to.

Each ViewRenderListener will be notified exactly once before every frame is rendered.

ViewRenderListener can determine if frame repaint is actually needed from its perspective. Frame will be rendered only if at least one listener says yes. This mechanism allows to save computing power and energy by skipping frame rendering when possible.

Specified by:

beforeRender in interface ViewRenderListener

Returns:

true if underlying view shall be re-rendered. If at least one of the view update listeners returns true, view is re-rendered.
