Do you have any recommendation for a free 3D charting library in Flex. To be more precise, I only need to draw surface (for now). Basically, I just need a chart that displays three axes (one should be timeline, and two should be linear axises) and the surface.

From what I have seen so far, two most popular free Flesh 3D libraries are Papervision3D and Away3D. Also, I've found one IBM library - ILOG Elixir that looks really nice, but it's proprietary (although, I haven't seen any surface examples for Elixir neither).

From what I have seen, Papervision3D and Away3D should do much more then 3D charting, but I haven't seen any examples on how to draw surfaces in any of them (except this line chart in 3D: http://www.insideria.com/2008/06/3d-charts-using-papervision3d.html).

So, if anyone has a link to a documentation or some examples that would be great. Also, I'm interested to hear your opinion and recommendations on this topic.

Thanks.

check out Defraga

Its an open source declarative graphics framework. It may not have the 3d Charting options but its pretty useful in developing Rich user interfaces.

It looks interesting. Although, as you've pointed out, it doesn't have support for 3D charting.

true..you can always make your own 3d charts using these frameworks else you have to pay for the license :)

Yeah, if nothing else helps I'll implement component myself. But I was kind of hoping that somebody has already done something similar, since this is something that's like a general problem (I presume that a lot of developers had a similar problem before).
