You are initializing the device on a different thread than the render loop. There are issues with that, OPENGL will then show a black screen. Try DirectX8 or 9 and it should work, or choose to run the control + irrlicht on the same thread.

       private void IrrlichtInit()
        {
            device = new IrrlichtDevice(DriverType.DIRECT3D9,
                new Dimension2D(pictureBox1.Width, pictureBox.Height), 16,
                false, false, false, true, pictureBox.Handle);

            driver = device.VideoDriver;
            tex = device.VideoDriver.GetTexture(@"C:\irrlicht-1.0\engine\Data\color.tga"); 

            while (device.Run())
            {
                device.VideoDriver.BeginScene(true, true, new Irrlicht.Video.Color(128, 128, 0, 255));

                // driver.Draw2DImage(tex, new Position2D(10, 10));
                // device.SceneManager.DrawAll();

                device.VideoDriver.EndScene();
            } 

        }

In the constructor of your form after

Code: Select all

InitializeComponent();

Use

Code: Select all

CheckForIllegalCrossThreadCalls = false;

It's seems to be working even with OpenGL! BIG TKS!

Code: Select all

       private void IrrlichtInit()
        {
            device = new IrrlichtDevice(DriverType.OPENGL,
                new Dimension2D(pictureBox1.Width, pictureBox.Height), 16,
                false, false, false, true, pictureBox.Handle);

            driver = device.VideoDriver;
            tex = device.VideoDriver.GetTexture(@"C:\irrlicht-1.0\engine\Data\color.tga"); 

            while (device.Run())
            {
                device.VideoDriver.BeginScene(true, true, new Irrlicht.Video.Color(128, 128, 0, 255));

                driver.Draw2DImage(tex, new Position2D(10, 10));
                device.SceneManager.DrawAll();

                device.VideoDriver.EndScene();
            } 
        }

If you are running Irrlicht in another thread, you don't need to send the control across, you just need to send the control's height/width and the handle.

It is possible to use addCameraSceneNodeMaya() or addCameraSceneNodeFPS() in a WinForm? (If yes how?)

Code: Select all

cam = device.SceneManager.AddCameraSceneNodeMaya(null, -250, 100, 100, -1);

Sure, they work as intended, but they do take over your control device. If you want to use a Window dialog or such with it, then you'd have to set the ActiveCamera's HasControl (sorry, don't have the exact method right now as my dev PC is not fully functional right now) property to false. Then when you leave the dialog you can set it back to true.

Here is the online documentation. I can't find anything in the ICameraSceneNode class.

help help!

In the scenemanager object there is an ActiveCamera property which has an InputReceiverEnabled property. Set the InputReceiverEnabled to false when you want to regain input control from Irrlicht and set it to true when you want Irrlicht to take over again.

Found! Tks I will try it later.
