Graphics / New to SFML, need help with World to Screen

That would work for this example I suppose. I'm tracing the orbits of stellar bodies as well however, and for that I need to be able to draw the lines exactly where they were. Drawing small circles or lines between their positions every frame with SFML is incredibly inefficient so I'd like to go the native route and write directly to a RenderImage with OpenGL, but for that I need to have the perspective just right so that the image lines up with what the user is actually observing so that the paths of their orbits are in sync with the stars themselves. Which is why I was looking for World to Screen function so that I could lessen the math a little bit...
I'll figure something out either way I'm sure :wink:
