PDL::Graphics::TriD::GL(3pm)

Overview

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.

It defines an interface that subclasses will conform to, implementing support for GLFW, GLUT, X11+GLX, etc, as the mechanism for creating windows and graphics contexts.

Config

Defaults to using OpenGL::GLFW - override by setting the environment variable "POGL_WINDOW_TYPE" to "glut", "x11" , or the default is "glfw". This is implemented by "PDL::Graphics::TriD::Window::gdriver".

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:

glfw - use Perl OpenGL bindings and GLFW windows (no Tk)

glut - use Perl OpenGL bindings and GLUT windows (no Tk)

x11 - use Perl OpenGL (POGL) bindings with X11

default_options

default options for object oriented methods

swap_buffers

OO interface to swapping frame buffers

set_window

OO interface to setting the display window (if appropriate)

Support

PDL uses a mailing list support model. The Perldl mailing list is the best for questions, problems, and feature discussions with other PDL users and PDL developers.

Acknowledgements

TBD including PDL TriD developers and POGL developers...thanks to all.
