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()
.
