I am trying to do a little drawing app that fades away with time.
For that I am connecting a series of points with ofLine and I add an ofCircle in the end to make the line smooth.
My problem is the following: When I call glBlendFunc() to modify the way the drawing fades the function ofCircle stops working (so the line is not smooth anymore).
Here are images for both cases:

Does anybody have an idea of why is this happening?
Thanks in advance!
