NAME

Graphics::GVG::OpenGLRenderer - Take a GVG file and turn it into Perl/OpenGL code

DESCRIPTION

ATTRIBUTES

circle_segments / ellipse_segments

In OpenGL, circles aren't really circles. They're polygons with a large number of sides, which blur together enough to look like a circle.

These attributes control how many sides those polygons will have. A circle or ellipse that appears larger on the screen will need to be rendered with a larger number of sides to maintain the illusion.

The default is 40 for both.

METHODS

make_drawer_obj

my $opengl = $renderer->make_drawer_obj( $ast );

Given an Graphics::GVG::AST object, generates a new Perl object that, when you call its draw() method, will output the GVG description to OpenGL.

The package will be uniquely created under Graphics::GVG::OpenGLRenderer.

make_code

my $pack_code = $renderer->make_code( $ast );

Given an Graphics::GVG::AST object, returns the code that can be used to create the same kind of Perl object made by make_drawer_obj().
