Irrlicht Engine

ok, it has nothing to do with the viewport or other 2D objects. When I load the meshes right away and set the shadow immediatly it works. But when I optionally set the shadow it doesn't work.

ShadowVol = (pScreenOb->EdSScr[0].EdEl[1].pElNode)->addShadowVolumeSceneNode();

This is called when I ...

Hi, I have a problem with shadows. When I use a very simple environment with no viewport and no 2D Elements the function addShadowVolumeSceneNode works. But as I set an viewport and have a 2D Window in the background of my meshes the shadow doesn't work. I have no idea why. Normally the shadow ...

I tried it with just getPosition but for me there is no difference... Well I have some more tests too...

Thanks Thulsa, although you are doing that also for your own project you are helping me a lot.
Are trying the same source code than I am?

Anyway I tried your example above and that is my result:

in the projection view the bbnode is drifting from near to far and vice versa. That means, that when ...

Ok now I got it. Well it is definitly the orthographic view. But there are a lot of huge differences between using the normal projection matrix and the orthographic matrix.

1. difference:
in the projection view, when I just don't set the orthographic view with that: camera->setProjectionMatrix ...

Hi Thulsa Doom, thank your for helping me!!

I inserted your code from above and I have a billbordscene node as the background now, but how should I see now, where the line points to? Sorry for beeing so blind and unknowing!

That was actually a great idea.... but it didn't work. I transform the line with the orthographic matrix but the result was worse. The camera is already transformed as I set this line:

camera->setProjectionMatrix(MyMatrix);

But I guess I have to transform something like that, but I can't think of ...

You get this with the OnEvent function. Read a little bit about it, it is not difficult.

(event.EventType == irr::EET_MOUSE_INPUT_EVENT)

:?
May be some code will help? try this yourself. I used saigumis tutorial orthogonal again.

Hi,
same old annoying issue. But I am getting closer and for that I need your help again.
I still need a drag and drop function for meshes in an orthographic projection. That means I still need a correct collision detection. As I posted in the bug forum the function ...

for me a better solution in DirectX9 would help alot because that is what I am using

mm765 is right, it is not implemented for OPENGL yet but it is for Direct3D.

If you hack something together for your own transparancy and it actually works, I would really appreciate if you post the code here, because like I said I tried it too but can't get it to work right. May be you like to ...

I had the same problem and I couldn't solve it. There is a difference if you use darker or brighter backgrounds. I think (but it is too long ago) with a darker background, you can see the object. on white background you can't. But in both ways it was not the kind of transparancy I expected. That is ...

I tried to set other alpha values and the "transparency" of the object seems to change as it should. Is the alpha value bigger than 100 it gets more and more red like the original texture. Is the value smaller than 100 it turns more and more like the background color. But when I set another object ...

Please... Any ideas?
