WebI've studied what other techniques exist for anti-aliasing with OpenGL, and found things like FSAA, FXAA, SMAA, GBAA, GPAA etc. Apart from my lack of knowledge in area of shaders, all these techniques look like a huge overkill for such a basic task like drawing colored 2D polygons.

WebWith antialiasing enabled, non-integer line widths are possible, and pixels on the boundaries are typically drawn at less than full intensity. As with point sizes, a particular OpenGL implementation might limit the width of nonantialiased lines to its maximum antialiased line width, rounded to the nearest integer value.

WebThen we redraw discontinuity edges (such as silhouettes and material boundaries) as antialiased lines. For example, Figure 22-8a shows a single triangle drawn without antialiasing. Figure 22-8b shows its edges drawn as prefiltered antialiased lines. By drawing these lines on top of the original geometry, we obtain the result in Figure 22-8c.
