By setting different offset values to each text I could set all the positions of the texts at the center origin point. So when I rotate the pitch ladders all text labels rotate aligned with the pitch ladders.<br>
<br>
Actually I did a similar HUD using NASA World Wind Java. There is a TextRenderer class in WWJ API and by that way a text can be rendered on GLCanvas. So when the matrix is rotated all drawings and texts rotates. That was actually more easy to implement.<br>
<br>
If anyone knows an easier way please let me know.<br>
<br>
Thank you!<br>
