(...) Interesting, but complicated IMO :-) Shaders offer a much easier implementation, and (I suspect) a faster one. Geometry-shaders for preference, but the algorithm can be implemented using vertex-shaders or even ARB vertex-programs to support (...) (14 years ago, 16-Jun-10, to lugnet.cad.dev, FTX)

(...) So finally this brings us to a technique that combines the predictive abilities of the conditional lines with the runtime advantages of the stencil and BFC algorithms. Think of the conditional line as a pair of triangles with a shared edge (...) (14 years ago, 16-Jun-10, to lugnet.cad.dev, FTX)

(...) And another thing... The BFC technique actually has an advantage over conditional lines because it works on the entire scene after it's been assembled.
