Hi.
I’ve got a program where I have a triangle that takes up half the screen. When I resize the window, the triangle also changes size. Can anyone tell me how to make sure the triangle stays the same size no matter what?
Thanks.

I assume you setup your projection matrix with:
void gluOrtho2D(
GLdouble left,
GLdouble right,
GLdouble bottom,
GLdouble top
);
I assume you are giving it always the same values.
You must pass your window’s size instead:
gluOrtho2D(0, widht, height, 0);
