Hi,
I tried to add the text using the same piece of code at the place where i used to add straight lines.
The piece of code is exactly same as urs.
Shape3D tmpShape3D = new Shape3D();
PolygonAttributes tmpPolygonAttributes = new PolygonAttributes();
Appearance tmpAppearance = null;
Transform3D tmpTransform3D = null;
tmpShape3D = new Text2D("Hi ABCDEFGHIJKLMNOPQRSTUVWXYZ", new Color3f (Color.red), "Arial", 30, Font.BOLD);
tmpAppearance = tmpShape3D.getAppearance();
tmpPolygonAttributes.setCullFace(PolygonAttributes.CULL_NONE);
tmpAppearance.setPolygonAttributes(tmpPolygonAttributes);
tmpTransform3D = new Transform3D();
tmpTransform3D.setScale(0.5f);
tmpTransform3D.setTranslation(new Vector3f(1.0f, 1.0f, 0.0f));
TransformGroup tmpSingleComment = new TransformGroup(tmpTransform3D);
tmpSingleComment.setCapability(TransformGroup.ALLOW_CHILDREN_READ);
tmpSingleComment.addChild(tmpShape3D);
bgRed = new BranchGroup();
bgRed.addChild(tmpSingleComment);
bgRed.setCapability(BranchGroup.ALLOW_DETACH);
bgRed.setCapability(BranchGroup.ALLOW_CHILDREN_WRITE);
bgRed.setCapability(BranchGroup.ALLOW_CHILDREN_READ);
bgRed.setCapability(BranchGroup.ALLOW_CHILDREN_EXTEND);
transsceneWF.addChild(bgRed);
Here every time i have to create a new BranchGroup (bgRed) for each Text i add. Earlier in this place i was adding my lines objects depending upon there start and end possition.This was just to test.Also it does not thro any error or exception while adding text nodes.
But i am not able to see any text. can u telll whats wrong in this.....
