iOS 2D Graphics library?

[xArtx]

Hi Guys,
Is there a 2D graphics library for iPhone development?
I'm after functionality to draw lines between screen coordinates, and set/clear pixels.

Pls overlook this if there's something like this in the stock SDK.
This is coming from someone who hasn't got their Mac yet!
I'm looking at doing something like this for iPhone:

Don't know why there isn't a vector based GPS app for hiking yet??
Cheers, Art.

I think Core Graphics / Quartz (which is available both in the Mac and iOS SDKs,) is exactly what you're looking for for drawing 2D points, lines, and other primitives...

You might also want to check out cocos2d.

P.S. Although by the looks of that YouTube video, you might want a 3D library.

Check out OpenGL but you're probably going to be faster off using existing map code.

Even the 3D stuff in the video was done with a 2D graphics library.
I just adjusted the Y coordinate to give the appearance of height for each contour.

I've done a bit of reading about Quartz, and it appears to be what I want
Thx
