<br>
<br>About sending the camera's coordinates to screen text, I've found a solution elsewhere:
<br>
<br>
<br>Code:
<br>        Vec3f eye;
<br>        while ( !viewer.done() ) {
<br>                eye = viewer.getCamera()-><wbr>getInverseViewMatrix().<wbr>getTrans();
<br>                text1-><wbr>setText((L"Heading: " + to_wstring(eye.x())).c_str());
<br>                text2-><wbr>setText((L"Pitch: " +   to_wstring(eye.y())).c_str());
<br>                text3-><wbr>setText((L"Roll: " +    to_wstring(eye.z())).c_str())<wbr>;
<br>                viewer.frame()<wbr>;
<br>        }
<br>
<br>
<br>
<br>
<br>or
<br>
<br>
<br>Code:
<br>        Vec3f eye, center, up;
<br>        while ( !viewer.done() ) {
<br>                viewer.<wbr>getCamera()-><wbr>getViewMatrixAsLookAt( eye, center, up );
<br>                text1-><wbr>setText((L"Heading: " + to_wstring(eye.x())).c_str());
<br>                text2-><wbr>setText((L"Pitch: " +   to_wstring(eye.y())).c_str());
<br>                text3-><wbr>setText((L"Roll: " +    to_wstring(eye.z())).c_str())<wbr>;
<br>                viewer.frame()<wbr>;
<br>        }
<br>
<br>
<br>
<br>
<br>Now the numbers change as I move the scene around using TrackballManipulator. However, the keys don't change any number when I use FirstPersonManipulator. I tried to look at the source code for examples:
<br>
<br>
<br>> grep -nrw . -e 'FirstPersonManipulator' --include=*.cpp
<br>
<br>
<br>but this only returns lines from osgGA/FirstPersonManipulator.<wbr>cpp
<br>
<br>How can I know how to use FirstPersonManipulator without a program that uses it?
