[osg-users] Change Perspective to Orthogonal View

[Robert Osfield]

Hi Rômulo,

You can simply via the Camera::setProjectionMatrixAsOrtho(...) method.
Have a look at the include/osg/Camera header.  Also have a look at
gluOrtho docs online to understand the parameters used and mean as the
OSG uses a 1:1 mapping in terminology and implementation.

Robert.
