Hi all,
I have created a slave camera. It should represent a rear mirror on a
vehicle.
It uses the master camera's scene data.
Its projectionMatrix offset is osg::Matrixd::scale(-1.0, 1.0, 1.0), so
that its view is mirrored.
But by using this offset projection matrix, every polygon's back face is
rendered instead of their front face.
I can modify the stateset of the master camera, such that double sided
rendering is enabled:
viewer->getCamera()->getOrCreateStateSet()->setMode(GL_CULL_FACE,
osg::StateAttribute::OVERRIDE | osg::StateAttribute::OFF);
However, this results in rendering double sided polygons for all my
cameras.
Trying to modify the stateset of a slave camera does not seems to affect
the scene:
viewer->getSlave(0)._camera->getOrCreateStateSet()->setMode(GL_CULL_FACE,
osg::StateAttribute::OVERRIDE | osg::StateAttribute::OFF);
So my question is:
Is it possible to use two cameras, where one is mirrored, that share the
same scene?
