opengl – How to draw circles with proper anti-aliasing?
Following the example given in the first code snippet of pyglet’s official documentation about shapes I clearly get a jagged edge to the circle, it is clearly not anti-aliased in any successful way on my system at least. Here’s my code and a screenshot:
import pyglet from pyglet import shapes window = pyglet.window.Window(fullscreen=True) batch = pyglet.graphics.Batch() circle = shapes.Circle(700, 150, 100, color=(50, 225, 30), batch=batch) @window.event def on_draw(): window.clear() batch.draw() pyglet.app.run()
So I am wondering whether it is so that pyglet does not directly cater for anti-aliasing with arcs, circles and lines.
And, how would you approach getting smooth circle/arc edges and smooth lines, using pyglet ― would you recommend a particular intervening (python) library for drawing smoothly-edged shapes? would you call OpenGL from pyglet’s own OpenGL bindings to smoothly accomplish it?
