Graphics / Re: Point not drawn in coordinates: (0,0)

I found the answer in
That the coordinate system in OpenGL is represented with the y-axis pointing up.
In SFML, the frustum was turned upside down,
So that the Y-axis is pointing down.
Because of this, everything that is on the X axis with y = 0 becomes invisible.

Graphics / Point not drawn in coordinates: (0,0)

« on: October 25, 2021, 09:17:30 am »

There is a code like this:

        sf::VertexArray ap (sf::Points,1);
                        ap[0].color    = sf::Color::Green;
                        ap[0].position = sf::Vector2f (0,0);

                        window.draw(ap);
 

Why is the green point not drawn in coordinates: (0,0)
