Hello,
how do I do in a simple OpenGL signal rocket (e.g. http://img.nauticexpo.com/images_ne/photo-m2/boats-parachute-signal-rockets-214947.jpg)?
Does not have to look totally realistic,
should be implemented quickly.
I do know that there are different types of light in OpenGL,
But I do not know how the rays make visible.
Thank you
