org.jzy3d.plot3d.text.overlay.TextOverlay

All Implemented Interfaces:

Renderer2d

Direct Known Subclasses:

SwingTextOverlay

public class TextOverlay
extends Object
implements Renderer2d

Highly experimental text renderer. The TextOverlay allows computing the 2d position of a text in the window, according to its required position in the 3d environment (using appenText method). As a 2nd pass, it might be rendered into a java Graphics context. The interesting thing, compared to the currently used TextBitmapRenderer, is that the user may select any java Font, whereas the TextBitmapRenderer only relies on Helvetica font provided by opengl. Actually no need to urgently correct these following todo: due to the problems related to post/pre rendering (blinking), this text Renderer is not used. An alternative would be to render the java text could be renderer into a Java Image that could in turn be rendered by opengl. // TODO: Verify alignement constants // TODO: Complete text renderer: select font, size, zoom // TODO: there may be a bug of non-rendering without resizing at init -> check that // TODO: the 1<->N relation TextRenderer<->Canvas won't work because TextRenderer has only one target Component.
