I am drawing lines in OpenGL on an app that will zoom way in and out on the surface. I would like the lines to always be visible.
Currently, when the line widths are small, at certain angles, the lines don't render. Specifically, I have a case where diagonal lines show but a horizontal one does not. The line width is way less than a pixel, but there is nothing else in the area of the pixels that are not being colored. Is there a way to force sub-pixel elements to cause the enclosing pixel (otherwise empty - nothing drawn there) to render the color of the sub-pixel element? What is the rendering algorithm that causes the sub-pixel line to render when at an angle but not when horizontal (and hence, at the same position in every pixel)? Can I change it? Is there any way to do this other than changing the line width based on the scaling I am doing to the underlying model as I display it on the surface?
