Hi:
I am a learner of OSG.Something puzzled me when I tried to set camera's
pitch,yaw,roll by osg::Quat.What I want to do is placing the camera at
(10.0f,10.0f,0.0f),then rotate 30 degrees by x axis.
After I execute the following code,I found that the camera is not at
what I want to place to,and the camera's pitch is not correct too.I do not
know what is wrong.
osg::Vec3 pos(10.0f,10.0f,0.0f);
osg::Matrix matrix;
matrix.setRotate(osg::Quat( osg::DegreesToRadians(30.0f),osg::X_AXIS,
0.0f,osg::Z_AXIS,
0.0f,osg::Y_AXIS));
matrix.setTrans(pos);
camera()->setViewMatrix(matrix);
