NAME

       SDL::OpenGL - a perl extension

DESCRIPTION

       SDL::OpenGL is a perl module which when used by your application exports the gl* and glu* functions into your application's primary
       namespace.  Most of the functions described in the OpenGL 1.3 specification are currently supported in this fashion.  As the implementation
       of the OpenGL bindings that comes with SDL_perl is largely type agnositic, there is no need to decline the function names in the fashion
       that is done in the C API. For example, glVertex3d is simply glVertex, and perl just does the right thing with regards to types.

CAVEATS

       The following methods work different in Perl than in C:

       glCallLists
		 glCallLists(@array_of_numbers);

	 Unlike the C function, which get's passed a count, a type and a list of numbers, the Perl equivalent only takes a list of numbers.

	 Note that this is slow, since it needs to allocate memory and construct a list of numbers from the given scalars. For a faster version
	 see glCallListsString.

       The following methods exist in addition to the normal OpenGL specification:

       glCallListsString
		 glCallListsString($string);

	 Works like glCallLists(), except that it needs only one parameter, a scalar holding a string. The string is interpreted as a set of
	 bytes, and each of these will be passed to glCallLists as GL_BYTE. This is faster than glCallLists, so you might want to pack your data
	 like this:

		 my $lists = pack("C", @array_of_numbers);

	 And later use it like this:

		 glCallListsString($lists);
