controlling a SceneGraphComponent with keyboard

[andre.s7]

Hello!

I'd like to rotate a SceneGraphComponent using the Arrow-Keys of the keyboard. In the tutorial I've only found help for creating a Tool from AbstractTool that handles Mouse input.

Can someone put me on the right track? :)

Thanks!

Maybe this helps...

Hello,

I wrote a small application which uses a stand-alone-viewer, just like in your tutorial ViewerFromScratch, but is there any way to use keyboard-input for the avatar-navigation (like WASD-keys for navigation with fixed y-axis)? I'm not able to find any hint on this topic but it works fine in the applications, that uses the vr-viewer...

thx for your help!

edit:
I was able to add a keylistener in my viewer-class, like this:

Code: Select all

Component comp = ((Component) this.getViewingComponent());
		comp.addKeyListener(new KeyAdapter() {
 				public void keyPressed(KeyEvent input)	{
					switch(input.getKeyCode())	{

					case KeyEvent.VK_W:

But, how do I edit the transformation-matrix of the transformation, that is bound to the camera, to move for example on x-axis?

edit:

I was able to handle translation about all 3 directions with this:

Code: Select all

m = camNode.getTransformation().getMatrix();
                       m[3]-=0.1;
                        camNode.getTransformation().setMatrix(m);

But, how can I handle rotation around z-axis? When I try like in the code above, it screws my perspective.
