You guys are the best!

I'm creating the object from scratch, so moved the object in object space and got a pivot in the object's center.

Excellent!

I see. How are these extra polygons positioned?

Why is this "workaround" necessary Egon?

Edit: My billboard's rotation pivot is not at origin but at 0;0 (unchanged), which I understand is not correct (http://www.jpct.net/forum2/index.php/topic,1253.msg8488.html#msg8488)?

Of course, you're right..

I want a billboard at the bulls eye, but it should appear in the middle when rotating. Its like the attachment point is wrong.

Take a look at the left texture below. The gray background is not this texture, but another texture on another object behind it.



The "a" has an outline which is painted using antialiasing (which is shown on the right image, which has no alpha values).

It seems to me that the alpha-channel is used, but not the values. Is this supported?

Edit: Using render with 4xAA

Exceptions or not. No error is shown in the console when changing resolution in gl mode (VideoMode supported). I've read Paradroidz does this. Do you have a link thats not broken?

(I remember to re-add the canvas to the pane.)

How is this done?

I want to use the opengl renderer, but if acquiring of the opengl render fails I should use the software renderer (see code).

If once used opengl, and then requiring to initialize the render again and fails, then the software renderer is not probably initialized. What do I miss? This reinitialization works fine on software renderer only.

try {
    // Set up open gl
    buffer = new FrameBuffer(width, height, glOversampling);
    buffer.disableRenderer(IRenderer.RENDERER_SOFTWARE);
    cGLScene = (AWTGLCanvas)buffer.enableGLCanvasRenderer();
} catch (Exception _) {
    // Use software-renderer
    buffer = new FrameBuffer(width, height, swOversampling);
    buffer.enableRenderer(IRenderer.RENDERER_SOFTWARE);
}

I've just updated the jar with the beta posted above, but with no effect.

// Scale on parent
mc.getOriginRoom().setScale(scale);

// Scale inverted on billboards (which are children)
for (RoomObject3D ro3d: mc.getRooms()) {
    ro3d.getBillBoardObject3D().setScale(bbscale);
You got my scaling right. Whatever I scale the parent, its children* is scaled with its reciprocal value (which worked fine before). This should leave the size of the billboards unchanged for the viewer.

Here are some numbers i use. scale is used on parent while bbscale on the billboards. What I get are bigger billboards (even on first setScale (for keeping the culumative out of the picture)).

scale=1.05, bbscale=0.952381, diff=1.0
scale=1.1024998, bbscale=0.90702957, diff=0.99999994
scale=1.1576248, bbscale=0.8638377, diff=1.0
scale=1.2155061, bbscale=0.82270265, diff=1.0000001
scale=1.2762814, bbscale=0.78352636, diff=1.0000001
scale=1.3400954, bbscale=0.74621564, diff=1.0000001
scale=1.4071001, bbscale=0.7106816, diff=1.0000001

*) Its childrens children actually.

Using the jar you just posting is not scaling the bill boards, when scaling its parent.
