Antialiased render

[tanffn]

I was thinking about creating a small game and for that I crated a small Vector based engine that uses SDL for the rendering ( :arrow: ).

For that I want to enrich sdlutils with more drawing functions, so far I’ve only been able to create an AA_line procedure (based on WuLine, no thickness), AA_Disc and AA_circle (both with thickness).
I still like to add:
AA_line with thickness
AA_Rect with thickness (border only and filled)
AA_Triangle with thickness (border only and filled)
AA_Bezier_Curve with thickness (opened/closed, border only and filled)

Now the problem is that my maths skills are not that good.. I have no problem implementing all types of basic shapes but it will be far from optimized..
So is there someone would like to join the effort?

I found this lib which looks great, translated from c++, barely readable..

Wow AggPas seems very comprehensive.

Thought its barely readable :cry: I wasn't able to follow the code..

Since it looks I’m the only one interested in those drawing functions I didn’t bothered uploading the code, thought I’ll ask Dom to include it to sdlutils.

The thick line function is problematic, it simply uses many AA_Line => performance and quality drop.
I still need to add polygon render function.

you can download the updated test app from here
Keys:
[*/] Rotate
[+-] Scale
[Arrows] to move the ant
[Key pad] to 'move the world'
[1..4 + mouse click] to control the curve
[5 + mouse click] to move the line

I think this is pretty cool set of functions and they look quite good.
If only they could be a faster.
