NAME

       PDL::Graphics::OpenGL::Perl::OpenGL - PDL TriD OpenGL interface using POGL

VERSION

       Version 0.01_10

SYNOPSIS

       This module provides the glue between the Perl OpenGL functions and the API defined by the
       internal PDL::Graphics::OpenGL one. It also supports any miscellaneous OpenGL or GUI
       related functionality to support PDL::Graphics::TriD refactoring.

       You should eventually be able to replace:

           use PDL::Graphics::OpenGL
       by
           use PDL::Graphics::OpenGL::Perl::OpenGL;

       This module also includes support for FreeGLUT and GLUT instead of X11+GLX as mechanism
       for creating windows and graphics contexts.

EXPORT

       See the documentation for the OpenGL module.  More details to follow as the refactored
       TriD module interface and build environment matures

FUNCTIONS

   TBD
   TBD
   new
       Returns a new OpenGL object.

         new($class,$options,[$window_type])

         Attributes are specified in the $options field; the 3d $window_type is optionsl. The attributes are:

       x,y - the position of the upper left corner of the window (0,0)
       width,height - the width and height of the window in pixels (500,500)
       parent - the parent under which the new window should be opened (root)
       mask - the user interface mask (StructureNotifyMask)
       attributes - attributes to pass to glXChooseVisual

       Allowed 3d window types, case insensitive, are:

       glut - use Perl OpenGL bindings and GLUT windows (no Tk)
       x11  - use Perl OpenGL (POGL) bindings with X11 (disabled)

   default GLUT callbacks
       These routines are set as the default GLUT callbacks for when GLUT windows are used for
       PDL/POGL.  Their only function at the moment is to drive a fake XEvent queue to feed the
       existing TriD GUI controls.  At some point, the X11 stuff will be deprecated and we can
       rewrite this more cleanly.

   default_options
       default options for object oriented methods

   XPending()
       OO interface to XPending

   XResizeWindow
       OO interface to XResizeWindow

         XResizeWindow(x,y)

   glpXNextEvent()
       OO interface to glpXNextEvent

   glpRasterFont()
       OO interface to the glpRasterFont function

   swap_buffers
       OO interface to swapping display buffers

   set_window
       OO interface to setting the display window (if appropriate)

   AUTOLOAD
       If the function is not prototyped in OO we assume there is no explicit mention of the
       three identifying parameters (Display, Window, Context) and try to load the OpenGL
       function.

   glXSwapBuffers
       OO interface to the glXSwapBuffers function
