SDL::OpenGL(3) User Contributed Perl Documentation SDL::OpenGL(3)NAMESDL::OpenGL - a perl extension
DESCRIPTIONSDL::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);
