Hi Markus,

You can do this all within the Producer config file.  There are
specific shear and rotate options available, both in the .cfg format
and the Preducer::Camera and Producer::CameraConfig.

One thing to note is that Don calls the projection matrix the lens.

Dear list,

   I need to shere/rotate the projective plane.  I need this in order to
correct the left and right channels of a three channel view where the
side channels are rotated by about 70°, something like this:
      __
     /  \

My understanding of OpenGL is, that I can rotate the projection matrix
but how is this done with Producer.  Producer::Camera only provides a
getProjectionMatrix() but no setProjectionMatrix().

Am I on the right way?  And if not, could someone please point me to a
resource on this topic?

Thank you

Markus
