Java Game APIs & Engines / Xith3D Forums / Rendering TransformGroups?

I'm looking to use 2D Text on my HUD, and have searched the board for others' solutions. DText2D by Goliat looks like the most promising one, but I can't get the text to render. How would I get a DText2D object to show up, being that it extends TransformGroup?

The foreground node is working fine, I just need to sync the coordinates up with the screen. Setting a Transform3D ortho is giving me bad results. If i have a 1024x768 screen, doing a trans.ortho(0,1024,0,768,0,1) stretches the y-axis (to make up for the difference, I guess). Other than this problem, it doesn't seem necessary to do the double-rendering job that the thread you suggested is proposing.

I am attempting to render some textured Quads in the front of the canvas. I was able to do this using plain JOGL with the following: 1

How would I go about doing this with Xith? I've been trying variations of the following: 1

| BranchGroup hud = new BranchGroup();
Transform3D t = new Transform3D();
t.ortho(0,1024,0,768,0,1);
hud.setTransformGroup(new TransformGroup(t));
Point3f [] coords = new Point3f[] {
new Point3f(0,0,-1f),
new Point3f(0,128,-1f),
new Point3f(128,128,-1f),
new Point3f(128,0,-1f)
};
QuadArray qA = new QuadArray(coords.length,GeometryArray.COORDINATES | GeometryArray.TEXTURE_COORDINATE_2);
qA.setCoordinates(0,coords);
Appearance a = new Appearance();
a.setColoringAttributes(new ColoringAttributes(new Color3f(1,1,1),ColoringAttributes.SHADE_FLAT));
Shape3D s = new Shape3D(qA,a);
hud.addChild(s); |
The quad renders at a clearly incorrect size. I have a feeling that it has something to do with the distance of the quad from the camera (-1f, in this case) as the original used Vertex2f, and had no Z component. Any suggestions? |
