Hi,
My scene graph looks like the image attached below:
Here, I want to rotate the geode1 along the axis normal of one of the vertices
of geometry that attached to the geode2. Imagine that the normal at the
vertex(0.0,0.0,0.0) of geode2 is (0.0,-1.0,0.0). i.e facing outwards from the
screen.
I have done something like this:
osg::Matrix localToWorld =
osg::computeLocalToWorld(geode2>getParentalNodePaths()[0] );
osg::Matrixd mat1,mat2;
mat1.makeTranslate(osg::Vec3d(0.0,0.0,0.0) * localToWorld);
osg::Vec3 vec(osg::Vec3(0.0,-1.0,0.0) * localToWorld);
vec.normalize();
mat2.makeRotate(osg::DegreesToRadians(45.f),vec);
trans->setMatrix( mat1 * mat2);
But the rotation is happening in a weird way.
Please let me know what could be the issue ?
Thank you!
Cheers,
