Anti aliased curved line

Hey guys, I was really bothered that there is no simple way to draw aa lines with LICE, so I started working on it... I will post schematics when it is done. Currently you can draw line by feeding it y coordinates, but you can't change it's thickness. Making ticker curved line is harder than you think. So far I have one solution, but it is not too CPU friendly...

I happened to stumble upon this a while ago, which might interest you: Not a proper solution, but hey, if it works...

I finally have some solution. This is a workaround for curved line until I figure how to draw anti aliased trapezoids, but I think that is good enough for use. I am not sure how it will perform on mac, but on smaller thickness (less than 10) it should be ok. BTW, anti aliased tick line is coming.. ;D Here is the code: Code:

Nice, but alternative with circles? Code:

Cool, thanks for sharing!

FWIW: I have just quickly timed my "optimised" version against the original, and mine seems ever so slighty faster (~1.5%); probably not worth the trouble. I guess most time is spent inside LICE_FLine(), which seems already pretty optimal.

Thanks Tale. Well only way to do this efficiently is to figure out how to draw anti aliased trapezoids (triangles). Then I expect it will be up to 8x times faster... I am working on it, but I don't have much free time to do it. I was thinking to use FillPolygon to fill the line and to draw anti aliased 1 px line on to of it to make it anti aliased, but FillPolygon is producing some strange results and it can be used only if you want non AA line.

You can see it in the code...
