I am drawing a series of connected lines that make up the outline of a shape.
When I render the shape with depth testing on, I get undesirable results (see attached file 1).
I have used very thick lines to illustrate this better, but each line segment of the curve when layed out in order seems to have a border that 'masks' the preceding line segment.
With depth testing off this doesn't happen (see attached file 2).
Anyone any ideas how to overcome this?
