[osg-users] osg_ProjectionMatrix

[Robert Osfield]

Hi Nikolai,

osg_ProjectionMatrix is the OSG version of the now deprecated GL's
gl_ProjectionMatrix.

It's value is set by the osg::Camera's setProjectionMarix() method, and is
the 4x4 matrix that transforms eye coordinates to clip space.

Robert.
