Rendering to moderngl fbo

[Yves33]

Hi all,

could someone point me to how to render an animation to a modernGL texture/FBO?
(documentation? tutorial? any minimal code?)
or is it just not possible?

thanks

class CustomScene(Scene):
    def construct(self):
        circle = Circle(radius=3, color=BLUE)
        self.add(circle)
        
class WindowEvents(mglw.WindowConfig):
    gl_version = (3, 3)

    def __init__(self, **kwargs):
        super().__init__(**kwargs)
        self.wnd.ctx.error
        self.fbo=self.ctx.framebuffer(color_attachments=self.ctx.texture(1200,720,3))
        ## first issue here!
        ## create scene but without creating a new opengl context, rather reusing existing one
	self.scene=CustomScene(render_target=self.fbo)
    
    def on_render():
	self.fbo.use()
	## render the scene
	self.scene.step()
	self.scene.render()
	## use imgui to render texture
		

if __name__ == "__main__":
    mglw.run_window_config(WindowEvents)
