In my entire application I work with cartesian coordinates(2 dimensions ) and everything is just fine . But finaly I need to display some points on the screen and I think that I need to convert my points from cartesian to screen coordinates and I have no idee how to do that.
for exp in cartesina coordinates
X axis [-200,200]
Y axis [-200,200]
that meens that for the screen coordinates
X axis is in the interva [0,400]
Y axis is in the interval [0,400]
I need some help with this "conversion" because I really don`t know how to do it;
