Package org.jzy3d.plot3d.text.renderers

Class TextBillboardRenderer

java.lang.Object

org.jzy3d.plot3d.text.AbstractTextRenderer

org.jzy3d.plot3d.text.renderers.TextBillboardRenderer

All Implemented Interfaces:

ITextRenderer

@Deprecated
public class TextBillboardRenderer
extends AbstractTextRenderer
implements ITextRenderer

Deprecated.

Use instead TextRenderer. A TextBillboardRenderer allows writing 2d text always facing the Camera of a 3d Scene.
TextBillboard provides the pixel definition of all characters of the ASCII alphabet. A default bitmap (plain rectangle) is provided for unrecognized characters (those that do not have an ASCII code). The bitmap library is static, and thus no overhead is generated by the use of several instances of TextBillboard. It is however not necessary to have an instance of TextBillboard for each drawn string.

 
 String s          = new String("2d text in 3d Scene");
 TextBillboard txt = new TextBillboard();
 BoundingBox3d box;
 
 txt.drawText(gl, s, Coord3d.ORIGIN, Halign.LEFT, Valign.GROUND, Color.BLACK);
 box = txt.drawText(gl, glu, cam, s, Coord3d.ORIGIN, Halign.LEFT, Valign.GROUND, Color.BLACK);
 
 

Layout constants As demonstrated in the previous example, the TextBillboardRenderer handles vertical and horizontal layout of text according to the given text coordinate.
