.. c:struct:: A3DGraphCameraData

   A complete description of a view point within a three-dimensional space (``A3DGraphCamera``\ ). 
   
   
      2.0
   
   
   
   A camera can be described as a virtual device within a three-dimensional space where properties allow a viewing application to generate a view point. A graphics application can use camera information to translate a graphics scene from world space to view, then projection space before submitting it to the next steps of its rendering pipeline.
