Hi Jae,
I'm afraid I don't have time available to go parsing all user code.
If you are having problem then consider taking a step back and
checking out the order which you are doing the ops in.

Hi
currently I am having trouble with view matrix
following is the code:
else if( key == '4')
{
pos_matrix = nvViewer::getOSGViewer()->getViewMatrix();
osg_User_Pos = pos_matrix.getTrans();
pos_matrix.get(RotQua);
trans_matrix.makeTranslate(osg_User_Pos);
rot_matrix.makeRotate(RotQua);
offset_rot_mat.makeRotate(
osg::DegreesToRadians(10.0), osg::Vec3(0,-1,0),
osg::DegreesToRadians(0.0), osg::Vec3(1,0,0),
osg::DegreesToRadians(0.0), osg::Vec3(0,0,-1)
);
view_matrix = rot_matrix * trans_matrix;
//view_matrix = trans_matrix * rot_matrix;
view_matrix = view_matrix * offset_rot_mat;
if(pos_matrix == view_matrix)
{
printf ("Two matrix matches \n");
}
else
{
printf ("not matches \n");
}
nvViewer::getOSGViewer()->setViewByMatrix(Producer::Matrix(view_matrix.ptr()));
osg_User_Pos = pos_matrix.getTrans();
printf("pos x: %f y: %f z: %f \n",
osg_User_Pos[0],osg_User_Pos[1],osg_User_Pos[2]);
osg_User_Pos = view_matrix.getTrans();
printf("view x: %f y: %f z: %f \n",
osg_User_Pos[0],osg_User_Pos[1],osg_User_Pos[2]);
printf("rot %f %f %f %f \n",
RotQua[0],RotQua[1],RotQua[2],RotQua[3]);
view_matrix.get(RotQua);
printf("rot1 %f %f %f %f \n",
RotQua[0],RotQua[1],RotQua[2],RotQua[3]);
return 1;
}
by using event manager, every time button 4 is pressed an event occurs
The event would be rotating the view to left.
This works well but only problem is the position of the view seems change as
well.
as you can see i did printf at the bottom, and xyz value seems change.
could you please tell me where i am going wrong with this?
thanks in advance.
Jae
