Hi all!
I'm still working on my shadow technique for OpenGL 3 shaders.
I only partially manage setting the matrix for the light camera creating
the shadowMap.
What I do:
osg::Vec3lightPositionVS=mainCamera->getViewMatrix()*lightPosition;
osg::Vec3eye;
osg::Vec3center;
osg::Vec3up;
mainCamera->getViewMatrixAsLookAt(eye,center,up,view->getDistance());
shadowDepthCamera->setViewMatrixAsLookAt(center,center+lightPositionVS,up);
That works quite fine except it doesn't honor the manipulations which are
usually done by the model matrix (scaling / translation).
So I guess I should do something like that:
osg::Vec3lightPositionVS=???->getModelMatrix() *
mainCamera->getViewMatrix()*lightPosition;
I have references to the view and to the mainCamera.
I found out that the model matrix is held by the cameraManipulator.
Unfortunately I couldn't find and way to get the manipulator from the
references I have.
Any other things I have to care about?
Or is there any other approach in setting up the shadowDepthCamera?
Any idea?
Thanks
