How to leave a trail in OpenGL?

Good afternoon. I would like to know how to leave a trail behind a moving point (GL_POINTS). Something similar to the picture. Thanks for the help!5cd87dba694bf155903786.png

instead of erasing the screen before each new frame, you need to make it darker (draw a translucent dark rectangle on top).

Draw 10 points with different levels of transparency.
